In simple terms, car modification can be divided into exterior modifications, interior modifications, power conversion, modification and manipulation of audio conversion. The results of a modified car represents the owner's taste as well as his views on driving. When human life into the e-age, car modification also added a new content: intelligence. However, in many conversion projects, the most exciting is the mechanical modifications, it is the owner of the car to be developed imagination and infinite potential perfect combination together. The main mechanical structure of an automobile can be broadly divided into: body, interior equipment, engine power, gearbox transmission, suspension, brakes and electronic control systems. This is the middle one if there are any changes made, the car itself will feel immediately affected and changed.
Appearance modification
Appearance of the body modification has been occupied a very important position, the general appearance of the modifications include stickers, body painting, logo, around the bar, surrounded by large, high-wing, opening engine cover, window visors, HID xenon headlights, front headlight decorative panels, front and rear perspective mirrors, lower body and so on.
Change the appearance of the body the fastest and most convenient way is to install aerodynamic package. The so-called aerodynamic package is commonly known as big bag, basically contains grille, side spoilers (side skirts), after scrambling plate surround and post-flow (tail), and sometimes we will see in the original insurance bars will install a lower spoiler, the general is called chin: if there is no insurance to replace the front and rear rod, just install the chin, it was also called packets. In addition to the installation of aerodynamic kit allows the vehicle more interesting to watch, as well as a more sporty, the most important thing is to have good performance improvement. Aerodynamic package installation does not make the vehicle run faster, strictly speaking, a good kit will usually reduce speed, be able to make the car more stable performance.
Power conversion
Like the human heart, as is the heart of the automobile engine, which is the most important part of the entire vehicle. And it is also the most troublesome modified its main modification is to increase its power output, conversion methods are: to increase the bore, increasing the compression ratio, Cadogan valve, naturally aspirated to turbo, etc., but must note that, modified engine is quite dangerous, a careless engine will be damaged, and even lead to serious security incidents.
Intake System
Engine work requires a lot of air, the air entering the engine through the air filter first, which is the most important part of the intake system, currently most original configuration are disposable paper filter. Modified products are made using special chemical fibers, its biggest advantage is in the air filter while the net flow of air into the combustion chamber, the flow rate increased by more than 30%, so that the fuel burn more fully, more efficient units, engine the performance of the natural well.
Ignition System
Engine ignition system is another element of the work, from spark plugs and ignition wire together constitute the original configuration are single set of harness, and passed on by the amount of voltage and current are not satisfactory.
FireWire high-voltage conversion with multiple sets of harness and high conductivity characteristics of the ignition coil can generate a lot of timely transfer to the spark plugs. Spark plug ignition system is the end of the group, using electrodes to ignite the oil and gas produced after mixing Mars, complete combustion, push the piston work. Original configuration and FireWire, are to reduce costs and make the minimum configuration. The owner if the replacement spark lines and spark plug, the car will throttle hard, start fast, sharp acceleration.
Exhaust System
Exhaust performance is directly related to engine performance merits. An increase in the intake, combustion intact, while the exhaust efficiency is also need to strengthen, high-performance exhaust pipe and muffler became the owner of the power to pursue the goal.
Handling modification brakes
In fact, the structural design of the brake system is relatively simple, but modified the workload is greater. Wants to enhance its braking performance, the fastest and most direct way is to change the high-performance brake pads. In addition, to upgrade the brake system can also change the brake fluid grade; facelift high-pressure brake hose or metal materials; addition is use larger brake times the force is to increase the auxiliary power brake pedal.
Chassis suspension
Related to the manipulation of the biggest driving factor is the car's chassis suspension system, the design of the original mass consumers generally accepted as the goal. Modified chassis suspension system can be divided into shock facelift, rod reinforced suspension structure, body rigidity strengthen other parts. Is the most influential person of the project is modified shock absorbers. Market shock absorbers types: Original enhanced, strengthened the original ride height adjustable, high professional sport, race-specific type. Owners should be based on their driving habits and needs to choose shock absorbers. CARPROG FULL V6.80
Tires
Tires are also very important, because a strong impetus good, sensitive brakes or, ultimately depends on the tire grip to achieve, and more professional career race car, dry pavement and rain should use different venues game the tires, off-road race is higher demands on the tires.
ECU system
Car at the factory when taking into account the car to sell to the world, to adapt to different environments and oil quality, so the program within the original ECU is the best compromise of a wide range of conditions, that is at least 30% -40 % of the energy is being sequestered (especially on security-famous European car). Especially on the ECU upgrade for trubo car can reach unexpected power lifting effect. CARPROG FULL V6.80
Chinese mainland for the automotive ECU tune into two basic ways: plug-in. Implantable. Plug-in is mainly for Japanese and Korean cars, the famous HKS. There implantable Germany Digi-Tec. The latter is the only continent registered legitimate ECU software upgrade. CARPROG FULL V6.80 with the arrival of China became the world's largest auto market, car modification has become a hot topic all car people. Faced with the numerous and brilliant modification world, advocating individuality you

The car suddenly stalled terrible it is important to identify the cause
Remember that period of time just to drive it? Remember it has repeatedly flameout? Remember the oil from the place it? Remember the clutch is always fast and flame lift it? Here follow me look at the car is turned off in the end is how it happened ...... Honda HDS HIM Diagnostic Tool With Double Board
Car flameout reasons:
1, the automatic transmission models will not easily appear flameout phenomenon, and models due to manual driving level is not high, may often stall phenomenon. But do not rule out the automatic transmission car flameout phenomenon does not occur, mainly due to the use of the fuel poor (many gas stations in order to reap huge profits selling impure oil) lead to engine deposits and stall. Honda HDS HIM Diagnostic Tool With Double Board
2 In addition, the reason for stalling the new car (automatic transmission) occurs mainly caused by driving skilled enough, another possibility is that the car engine or the oil problem, but for a new car, the possibility of a problem than the engine itself is small, because the passage of most of the problems. Honda HDS HIM Diagnostic Tool With Double Board
3, the last for the old models, the flame is not enough because in addition to driving skill, but it is not up to the quality of the oil using the engine flameout set of carbon as a result.
Automatic transmission car flameout troubleshooting methods:
Usually pay attention to places: For automatic transmission vehicles stalling phenomenon is caused by the fuel or the use of poor quality. First, the formal larger stations plus high-grade oil, for example, using 95 gasoline, although the price a lot more expensive, but you can protect your car longer life and the exercise of the power of good. But some owners freeloaders 92 plus oil, although the price a little lower, but problems may occur in the future. The second is to pass a large gas station!
Practice: left hand grasp the steering wheel to stabilize the direction (because there is no help, so be sure to firmly stabilize), right foot hard on the brakes to reduce the speed as much as possible, then quickly hit N AT stall speed, (note: the road to re-fight fire must be in the N range, can not be a D / R / P and other files, otherwise, the car or beat the fire, or the car will damage the gearbox), and then turn the key back a grid, and then re-ignition, then aT gear bit restored to normal driving D file. Honda HDS HIM Diagnostic Tool With Double Board
Manual car flameout troubleshooting methods:
1, for the novice, halfway flame is not a new topic, the main approach to rapid run-in after exclusion improve their driving skills.
2, the use of high-standard quality of qualified fuel.
3, a thorough cleaning of the oil line will include fuel injectors, throttle, fuel tank and so on. There may be you add the oil quality, but off, plastic fat too much, the oil passage blocked, the attack caused by poor oil.Honda HDS HIM Diagnostic Tool With Double Board
4, the cause of the failure to turn off idling vehicles under mainly due to too much dust in the air, the engine is running at idle speed motor with the throttle valve seat at the deposition has many dirt, when excessive accumulation of dirt, the engine will be idling too low, idle stability is poor, idling flameout occurs when traveling. To solve this problem is simple: just wash idle speed motor can be.
5, oil is smooth, it can easily lead halfway flameout.
6, long-term car park is not used. In fact, should not be parked for a long time. If parked a long time, before re-use should do a thorough maintenance, oil changes, filter, etc., and, where appropriate check fuel circuit. Your vehicle may cause long-term parking is because lubrication or circuit problem.

More efficient! Single twin-scroll turbocharger turbine principle to resolve
Nowadays turbocharged engine is very hot, with more power than the same displacement naturally aspirated engine, by many people of all ages. The turbocharger as a core part of its evolution is constantly upgraded, as nowadays some of the equipment to launch a single twin-scroll turbocharger turbine. Single turbo twin-scroll turbocharger and the general principles of what would be different? And how about the engine performance impact? Let us resolve it.
Single twin-scroll turbocharger turbine structure
Single turbo twin-scroll turbocharger with common structure similar turbocharger, exhaust gas can be simply understood as the entrance to a general increase in turbine exhaust passage, except that the turbine is driven by the exhaust gas of the two channels.
Exhaust gas turbocharger boost mode?
Exhaust gas turbocharger on the engine intake supercharger There are two main ways that the constant pressure and pulse supercharger boost. Is the constant-pressure turbocharger turbine inlet pressure of the exhaust duct is almost constant, even though the exhaust gas of each cylinder alternately, but the pulse voltage is superimposed and the effect of the exhaust pipe, the inlet pressure of the turbine is almost change.
Pressurized pulses, each cylinder is discharged through the exhaust gases and at different moments of the forming pulse, the pressure before the turbine is changed, the pressure wave in a pulse manner to drive a turbine. Impulse supercharging turbocharger can achieve fast response characteristic (especially at a lower speed), because this time the pulse of the strongest, whereas in the case of constant pressure supercharging turbo mode after the pressure difference is relatively small.
How to exhaust pulse generation?
We know that the working cylinder four-stroke engine, only the exhaust stroke exhaust gases, the pressure before the turbocharger the exhaust gas passage of the cylinder only when the exhaust stroke is the largest. In a multi-cylinder engine, the exhaust gas due to the different time of each cylinder, and therefore the exhaust gas passage before the turbocharger the exhaust gas pulses will produce corresponding. Such as single-cylinder engine, in theory, each crankshaft rotation 720 ° in there 180 ° for exhaust. The following figure with a very simplified way to display a pressure situation cylinder engine exhaust gas turbocharger ago.
In the four-cylinder engine, since the crankshaft rotates two turns after completion of the respective all-cylinder exhaust gas loop, so produced within the 720 ° of the crank angle of the four pressure waves, uniform distribution of the ignition interval of 180 ° crank angle intervals. In this process, the pressure wave superposed on each other when the cylinder pressure falls to a next cylinder pressure has been increased.
Superimposed effect will make the minimum pressure and maximum pressure difference significantly reduced, and therefore the pressure wave acting on impulse turbine also will be reduced, leading to the exhaust turbocharger boost pulse within reduced.
Single twin-scroll turbocharger turbine produces larger pulse supercharger
In a single twin-scroll turbine engine exhaust system, the exhaust duct is divided into two groups, such as the four-cylinder engine in the cylinder group 1 and 4, the cylinders 2 and 3 as a group, so that according to the ignition order, one channel the cycle interval of 360 ° crank angle, so even in the case of superimposed can produce a larger pulse supercharging, better utilization of the kinetic energy of the exhaust gas.
When the engine load is changed, the exhaust gas temperature and pressure changes can be quickly transmitted to the turbine, the turbine directly reflected by the compressor, so that a faster response of the turbocharger to changes in engine load, so that the engine can be improved better the acceleration characteristics and torque characteristics (low speed high torque can be generated).
Single twin-scroll turbo engine intake and exhaust design more efficient
The above mentioned four-cylinder engine cylinder 1 and the cylinder 4, the cylinder 2 and the cylinder 3 are integrated in one channel, why should the cylinder 4 and the cylinder 1 together with the set, rather than the set of cylinders and the cylinder 2 together with? In fact, there is another advantage to do so. Autoboss V30 Elite Scanner For Multi-brand Vehicles for sale
We know that the four-cylinder engine firing order is 1-3-4-2, the general turbocharger (single turbo single scroll) is an exhaust manifold of an exhaust pipe of all the cylinders together and to the exhaust pooled and then to push the turbine.
What's so wrong with that? When the work of a single cylinder, the resonant pulse generated by the exhaust gas will affect the efficiency of the exhaust gas of the other cylinder. When working as a cylinder, there is a period of time the cylinder intake valve and exhaust valves are in the open state (valve overlap). If the ignition interval between the adjacent two cylinder exhaust pipe connected when the valve overlap causes the exhaust gas back into the preceding cylinders. Before a cylinder intake air reduction, then the next cycle of the total power will drop.
And in a single twin-scroll turbine engine exhaust system, the two cylinders adjacent to the ignition twenty-two separate exhaust duct (1 and 4, a group, a group 2 and 3), so that when the cylinder 3 is completed when the exhaust acting , a cylinder is entering the intake stroke, due to a cylinder and 3-cylinder exhaust pipe is not connected, so the three-cylinder exhaust does not affect a cylinder intake effect (other empathy), so the two adjacent ignition cylinder intake and exhaust without interference effects of intake can increase the displacement of each cylinder, thus effectively improving engine efficiency.
Single twin-scroll turbo-charged engine characteristics
BMW N20 turbo engine uses a single twin-scroll turbocharger technology, 1250 at low speed can reach 350Nm of peak torque (high power version), and can be continued until the 4800 revolution, covering almost daily driving use to the speed range. Autoboss V30 Elite Scanner
Single turbo twin-scroll turbocharging system, the ignition timing according to engine exhaust pipes adjacent cylinder exhaust pipes were divided into two groups to promote the turbine work, have a stronger pulse supercharger and exhaust more fully. Compared to ordinary turbocharged engine, single twin-scroll turbo engine effectively relieve hysteresis at low speeds, making the engine's peak torque outbreak earlier, better fuel economy.

Antilock braking system (ABS) and working principle
In the automotive braking, if the wheels from locking slip, lateral adhesion between the wheels and the road will completely disappear. If only the front wheel (steering wheel) brake to lock the rear wheels slip while still rolling, the car will lose steering ability. If only the rear brake to lock the front wheels slip while still rolling, even by small lateral disturbance force, the car will also have a slip (drift) phenomenon. These are easily cause a serious accident. Therefore, you do not want the car when braking wheel brake to lock slip Autel MaxiCheck Airbag ABS SRS Light Service Reset Tool, but hope to edge trim wheel brake slip state.
By experiment that, car wheel slip rate at 15% to 20%, between the tire and the road surface friction coefficient has the largest. So in order to give full play to the ability of this potential adhesion between tire and road, currently on most vehicles are equipped with anti-lock braking system (AntilockBrakeSystem), referred to as ABS . our shop supply Autel MaxiCheck Airbag ABS SRS Light Service Reset Tool
ABS composition and working principle
Typically, ABS wheel speed sensor is the installation of the braking system on the basis of the ordinary, ABS electronic control unit, brake pressure regulating device and other components of the brake control circuit.
During braking, ABS electronic control unit (ECU) 3 continuously obtained from the wheel speed sensor 1 and the signal 5, and processed, to analyze whether there is a wheel is about to lock the slide drag.
If no trailer wheel slip is about to lock, the brake pressure regulating means 2 is not involved in the work, the brake master cylinder of the brake cylinders 7 and 9 in communication, the brake wheel cylinder pressure continues to increase, namely, ABS braking process the pressurized state.
If the electronic control unit determines that the individual wheels (assumed to be a left front wheel) is about to drag the locking slide, namely a brake pressure regulating means which issues a command to close the left front brake master cylinder and the wheel brake cylinder passages and the front left system wheel cylinder pressure no longer increases, namely ABS braking process of packing state.
If the electronic control unit determines that the locking of the left front wheel tends to drag the slider still state, namely it issues a command brake pressure regulating means, to open the left front wheel brake cylinder and the reservoir chamber or the accumulator (not shown) the channel, so that the left front wheel cylinder braking oil pressure decreases, namely, the pressure during ABS braking condition.
ABS hydraulic control assembly structure ,to buy Autel MaxiCheck Airbag ABS SRS Light Service Reset Tool visit our shop www.obd2works.com
ABS hydraulic control assembly is in the hydraulic unit on the basis of ordinary braking system designed after the installation of ABS brake pressure regulator formed.
Hydraulics ordinary braking system generally includes brake booster, brake master cylinder, double chamber, reservoir chamber, brake wheel cylinder and dual hydraulic lines and so on. In addition to the hydraulic braking system outside an ordinary member, ABS brake pressure regulator usually consists of an electric pump, the accumulator, the main control valve, the solenoid control valve and some control switches and other components. Essentially, ABS system is controlled by a hydraulic control valve solenoid on the valve body Cylinder quickly becomes larger or smaller, in order to achieve the anti-lock braking function.
(1) electric pump
The electric pump is a high pressure pump, which can be pressurized brake fluid in a short time (in the storage vessel) to 15 ~ 18MPa, and the entire hydraulic brake system provides a high pressure liquid. Electric pump can be started in the car to complete the work within one minute. Electric pump operates independently of the ABS computer, computer failure or wiring if there is a problem, the electric pump can still work.
(2) the accumulator
Diverse forms of energy storage structure. Autel MaxiCheck Airbag ABS SRS Light Service Reset Tool used more as a piston - spring-accumulator, the accumulator located between the solenoid valve and back to the pump, the wheel cylinder to the hydraulic fluid into the accumulator, thereby compressing the spring so that the hydraulic accumulator cavity volume change large to temporarily store the brake fluid.
(3) solenoid control valve
The electromagnetic control valve is an important component of the hydraulic actuator, it is done by the control of the ABS. ABS systems have one or two solenoid valve, which has a plurality of solenoid-controlled valve, the front and rear wheels, respectively, brake control. There are three commonly used three-way solenoid valves and two two-way valves and other forms.
(4) pressure control, pressure and level warning indicator switch
Pressure control switch (PCS) working independently of the ABS computer, monitoring the pressure of the lower chamber of the accumulator. Pressure Alarm Switch (PWS) and level indicator switch (FLI) function is, when the pressure drops to a certain value (14MPa or less) or when braking level drops to a certain extent, the fault indicator lights and ABS braking system fault indicator, while allowing the ABS anti-lock brake computer stops working.
By experiment that, car wheel slip rate at 15% to 20%, between the tire and the road surface friction coefficient has the largest. So in order to give full play to the ability of this potential adhesion between tire and road, currently on most vehicles are equipped with anti-lock braking system (AntilockBrakeSystem), referred to as ABS . our shop supply Autel MaxiCheck Airbag ABS SRS Light Service Reset Tool

If the electronic control unit determines that the individual wheels (assumed to be a left front wheel) is about to drag the locking slide, namely a brake pressure regulating means which issues a command to close the left front brake master cylinder and the wheel brake cylinder passages and the front left system wheel cylinder pressure no longer increases, namely ABS braking process of packing state.
If the electronic control unit determines that the locking of the left front wheel tends to drag the slider still state, namely it issues a command brake pressure regulating means, to open the left front wheel brake cylinder and the reservoir chamber or the accumulator (not shown) the channel, so that the left front wheel cylinder braking oil pressure decreases, namely, the pressure during ABS braking condition.

ABS hydraulic control assembly is in the hydraulic unit on the basis of ordinary braking system designed after the installation of ABS brake pressure regulator formed.
Hydraulics ordinary braking system generally includes brake booster, brake master cylinder, double chamber, reservoir chamber, brake wheel cylinder and dual hydraulic lines and so on. In addition to the hydraulic braking system outside an ordinary member, ABS brake pressure regulator usually consists of an electric pump, the accumulator, the main control valve, the solenoid control valve and some control switches and other components. Essentially, ABS system is controlled by a hydraulic control valve solenoid on the valve body Cylinder quickly becomes larger or smaller, in order to achieve the anti-lock braking function.
(1) electric pump
The electric pump is a high pressure pump, which can be pressurized brake fluid in a short time (in the storage vessel) to 15 ~ 18MPa, and the entire hydraulic brake system provides a high pressure liquid. Electric pump can be started in the car to complete the work within one minute. Electric pump operates independently of the ABS computer, computer failure or wiring if there is a problem, the electric pump can still work.
(2) the accumulator
Diverse forms of energy storage structure. Autel MaxiCheck Airbag ABS SRS Light Service Reset Tool used more as a piston - spring-accumulator, the accumulator located between the solenoid valve and back to the pump, the wheel cylinder to the hydraulic fluid into the accumulator, thereby compressing the spring so that the hydraulic accumulator cavity volume change large to temporarily store the brake fluid.
(3) solenoid control valve
The electromagnetic control valve is an important component of the hydraulic actuator, it is done by the control of the ABS. ABS systems have one or two solenoid valve, which has a plurality of solenoid-controlled valve, the front and rear wheels, respectively, brake control. There are three commonly used three-way solenoid valves and two two-way valves and other forms.
(4) pressure control, pressure and level warning indicator switch
Pressure control switch (PCS) working independently of the ABS computer, monitoring the pressure of the lower chamber of the accumulator. Pressure Alarm Switch (PWS) and level indicator switch (FLI) function is, when the pressure drops to a certain value (14MPa or less) or when braking level drops to a certain extent, the fault indicator lights and ABS braking system fault indicator, while allowing the ABS anti-lock brake computer stops working.

The new owners of the oil temperature maintenance are a lot of misunderstanding
In recent years, car owners gradually increased, cars require regular maintenance, but a limited number of qualified car repair center, often into maintenance errors, affect the performance of the vehicle.
Afraid of heights afraid of low engine temperature. Do everything possible to find the cause of high water temperature, low water temperature is considered normal. In fact, great harm automobile engine temperature is low, the mixture will not burn fully, power reduction, increase, and cause poor lubrication, can also cause excessive emissions.
Add oil more the better. Think of the engine plus oil rather more not less, plus less likely to burn bearing little relationship Cadogan point. In fact, the right engine oil Cadogan still cause harm, Tcs cdp diagnostic tool ramp-mounted engine and V-type engine is even worse. It is an increase of the crankshaft, connecting rod rolling resistance, but it increased oil splashed on the cylinder wall, resulting in increased carbon deposition chamber. So oil Cadogan, and will reduce engine power, increased wear, can cause excessive emissions.
Empty hub lubrication unreliable. That the inner hub filled with grease, can ensure the lubrication of wheel bearings, the bearings coated with only the empty hub lubricating greases not insurance, the hub must be in the middle of the gap filled with grease. In fact, doing so is not only a waste of grease, bearing the heat and the impact of harmful and no interest bearing lubrication. Breaker contact gap big points better than the small point. In fact, the contact gap is too large, contact closure time is short, the primary side of the ignition coil current is reduced, causing the high-voltage spark is weak, thus causing the engine difficult to start.
Do not loose fastening bolts rather tight. In fact, the various components of the bolt car, depending on the diameter, pitch and uses its size has a corresponding tightening torque specified value. Less than the required value of the bolts come loose, although bad, but blindly increasing the tightening torque fastening parts will be deformed and cause elongation of the screw thread deformation or fracture.
Open when the car maintenance check was assured. With the improvement of manufacturing standards, modern life has been greatly extended auto parts, casual dismantling will disrupt been running good with the state, greatly shorten the life of the part. In the automotive fault detection technology is improving without disassembly today, if part or assembly has not found significant failures are generally not dismantling.
Car break-in period is not important. In fact, the most important vehicle maintenance stage is car break-in period. During the run, the engine will produce some iron, iron if there is no immediate clean-up will cause internal engine wear and tear, as well as the piston will have abnormal wear and tear, so that later may have to eat the oil for the car or the phenomenon of incomplete combustion .

Automotive Digital Diagnostic Tools Ignition System Quick detectors
COP ignition system fast detector is a portable, handheld detector ignition system car diagnostic scanner. It can be simply and quickly detect COP ignition system (ignition coil and spark plug in-one) in the ignition coils and spark plugs are firing properly. Detector can trigger its work by the secondary coil of the ignition signal. When the signal is received, the detector can detect the COP ignition voltage (peak voltage or a voltage of combustion) and combustion time (spark duration) is normal. When the ignition voltage is normal, red strobe light-emitting diodes will flash. Arcing duration is normal, green strobe light-emitting diodes will flash. Red strobe flashing light-emitting diode continuous and regular and accompanied by a beep, indicating that the ignition voltage is normal. Does not reflect or to reflect the ongoing show ignition coil ignition voltage is not enough.
This product can easily detect the following faults:
1) spark plug gap is dirty or inappropriate
2) or the connection line is damaged or corroded
3) Coil car computer failure or malfunction
Green strobe flashing light-emitting diode continuous and regular shows that the burning time is normal. Or does not reflect persistent flashes to indicate that the burning time is not normal.
The measuring device can detect asked causes:
1) ignition coil short
2) there is resistance or open circuit failure in the primary or the secondary coil
3) coil failure
Without the use of detectors shutdown for about 2 minutes, the automatic shutdown. Off the first two strobe flashing LED lights, and the detector beeps emitted gradually reduced, how very human right, I believe that with such a compact and fully functional testing tool will bring it to a repair Great benefits.
