Is there any car power modification in China?

There are still a lot of car power modifications in China.

You can install a mechanical pressurization device, which is a more secure solution, and the annual inspection is worry-free, and you can add V jackzhai80 to communicate.

It is illegal to illegally modify the vehicle without permission.

The Road Traffic Safety Law clearly stipulates that no unit or individual shall engage in any of the following acts:

1) Assembling a motor vehicle or changing the registered structure, structure or characteristics of a motor vehicle without authorization;

2) Changing the motor vehicle model, engine number, frame number, or vehicle identification number;

3) Forging, altering, or using forged or altered motor vehicle registration certificates, license plates, driving licenses, inspection marks, or insurance marks;

4) The use of other motor vehicle registration certificates, license plates, driving licenses, inspection and training marks, insurance marks.

Engine Modification Ignition System Modification Intake Modification.

1. Engine modification.

The engine modification mentioned here is not a modification of a piston cylinder liner or the like, after all, it is illegal. In fact, the most effective way to improve the power is to upgrade the ECU program, which can change the ignition time, fuel injection time, speed limit, torque limit, etc. of the engine, so that the engine can throw off all the constraints and let itself fly.

For a specific example, you can refer to the tenth-generation Accord, the same engine, under different ECU programs, the power has been directly increased from 130kW to 143kW, and the torque has been increased from 10% on the basis of the original power. If it is a normal engine, a 20% increase in power is not a problem.

2. Ignition system modification.

The ignition system is an important part of the engine, and the ignition system includes the power supply, ignition trigger signal, ignition time control signal, high-voltage ignition coil, high-voltage electrical wire and spark plug. The quality of ignition performance and the time of ignition will affect the combustion efficiency of the fuel and indirectly affect the power of the engine.

Therefore, the modification of the ignition system is mainly to make up for the shortcomings of the ignition system of the original car, and the goal of the modification is to accurately ignite the time, improve the ignition intensity, prolong the ignition time, and reduce the voltage transmission loss. To achieve these goals, it is necessary to replace the high-voltage conductors with lower resistance, the spark plugs with higher ignition performance, and the ignition coils with faster voltage transformation.

3. Air intake modification.

Nowadays, many ** lines modify the exhaust pipe, it seems that the installation of a large-caliber and amazing exhaust pipe can improve the power of the engine, in fact, this is a misunderstanding, the modification of the exhaust pipe for the improvement of power can be said to be minimal. For some naturally aspirated engines with small displacement, modifying the air intake is actually a very effective way to increase the power intake, the purpose is to increase the air intake of the engine.

There are several ways to modify the air intake, replacing the high-performance intake manifold is a very effective way, most of the intake manifold of the original car is cast and turned to produce, the inner wall of the manifold is rough, the casting line is obvious, which directly affects the intake efficiency and smoothness of the airflow, the inner wall of the high-performance intake manifold is smoother, the intake efficiency is better, and there will be no loss. In addition through modifications.

The main modifications are engine modules, such as cylinders, combustion speed, fuel, etc., but such modifications are currently illegal at the national level and require a license to be obtained.

Hello: Automobile power modification can start from the following aspects.

1. Engine intake modification.

2. Engine exhaust modification.

3. Turbocharged modification.

4. Brush programs such as: 1st order 2nd order.

Turbo will do, Warren can quickly increase torque.

Words, I think you can put one.

At present, the method of increasing the compression ratio of cylinders in modified cars is to replace thinner cylinder gaskets to reduce the volume of the combustion chamber, so as to achieve the effect of increasing the compression ratio. In general, it is to improve the air pipe, change the air filter, and change the supercharger.

The first way to increase air intake is to replace a regular air cleaner with a high-flow air cleaner. Because the engine will produce various resistances in the process of operation, so that the actual amount of air inhaled into the combustion chamber of the engine does not reach the standard value, so changing the ordinary air filter element to a high-flow air filter element to reduce the intake resistance is the simplest and more common modification method.

The second way to increase the air intake of the engine is to modify the air intake pipe, by installing a supercharger in the air intake pipe, so that the air inhaled by the engine becomes similar to turbocharging, so as to increase the air intake of the engine.

The third type: because the combustion efficiency of the engine determines the explosive power of the mixture, and the explosive power of the mixture determines the power of the vehicle, so how to complete the combustion process of the mixture in the shortest time and produce the maximum explosive force is the key to improving the power of the vehicle. The easiest way to make the engine more explosive during combustion is to increase the compression ratio, just like Mazda's Skyactiv technology.

Automobile power modification generally does the following 4 items: 1. MAX ignition combustion aid: add an alarm "MAX ignition combustion aid" on the ignition coil, the principle of which is to use the current to excite the spark plug, so that the spark plug and gasoline are fully combusted, so as to reduce the formation of carbon, improve the power, and reduce fuel consumption!

Non-destructive installation does not hinder the annual review, the ignition is more rapid, the throttle response is sensitive, the acceleration is accelerated, the power is increased by at least 15 20%, the anti-carbon protection engine, a tank of oil can travel more than 50 70 kilometers;

2. Turbocharging is a technology that uses the exhaust gas generated by the operation of an internal combustion engine to drive an air compressor. Liquid Wisdom is similar to the function of a supercharger (mechanical supercharger), both of which increase the flow of air into an internal combustion engine or boiler, thereby increasing the efficiency of the machine. Turbochargers are commonly used in automobile engines to use the heat and flow of exhaust gases to increase the horsepower output of an internal combustion engine.

Under the premise of the same displacement, the power and torque of the engine can be greatly increased, about 40%, that is, it can be approximately equal to, the fuel burns more fully;

3. Brush ECU, the working state and power of the engine are controlled by the ECU, including ignition angle, fuel injection, fuel injection time, mixed gas concentration, etc., after correct adjustment, these data will be recombined, and the engine will look new;

4. The air cracked filter on the high-flow air filter engine is to filter the air required for the operation of the engine, and there is this device on the gasoline engine, and the air filter installed on the original car seems to be insufficient.

Millions of car purchase subsidies.

There is no doubt that the BRZ and 86 are very fun to drive, and it is worth mentioning that their starting prices are not very high, and they are easy to obtain, and there is a certain amount of ownership in the country. Due to its sporty and compact shape, if you don't want to give it a deep makeover, a replacement rear wing or a surround can greatly improve its appearance.

Although its boxer engine is only about 200 horsepower, it has a very good potential for improvement, and the tuning of the chassis can also bring a very good driving experience, whether it is straight acceleration or drifting. It is worth mentioning that in addition to the kits provided by their own tuning factories such as TRD and STI, there are many modification solutions with a high degree of completion created by many tuning factories in Japan, Europe and the United States.

Even if you're not happy with its boxer-opposed engine, you can replace it with a Ferrari V8 engine, which has been the case, and this powerful output of 86 is completely up to the task.

Look at how much the price is!

150,000 or less, 1, Honda Civic, 2, Mazda 3, 3, Volkswagen Polo, 4, Honda Fit, 5, Toyota C-HR

More than 150,000 can't afford to buy and haven't seen it.

Subaru Impreza, good foundation, strong power, dynamic and avant-garde appearance, spend another 200,000 to modify and strengthen, brush the second-order program Four or five hundred horsepower

Any car will do, as long as you have a mine at home.

Honda Civic, if you buy it back and don't modify it, you're embarrassed to drive it out.

Honda Civic, does not accept rebuttals.

There are four ways to modify them.

1. High-flow air filter. The air filter on the engine is to filter the air required for the operation of the simple motor, and there is this device on the gasoline engine. The keys to the car rider have the convention of modifying the air intake system.

The air filter for ordinary modification varies from model to model**, fluctuating between 350 yuan and 800 yuan. 10,000 km to 30,000 km needs to be cleaned or replaced, and maintenance and replacement are cheaper.

2. Modification of exhaust system. After the intake system is modified, the exhaust system also needs to be further modified. At present, it is popular to change the tail section of the exhaust pipe to a direct exhaust method.

From the back, you can see a thick exhaust vent, and you can feel that the vehicle seems to be very powerful. If you change both the front and middle sections of the exhaust system, you need a professional to do it. Because the exhaust is too smooth, it may affect the torque of the engine at low rpm; When changing the front and middle sections of the exhaust pipe, it is necessary to pay attention to the technical content and the actual test.

3. Changes in the ignition system of the engine. There is also a popular option for modifying the engine ignition high-voltage line and spark plug to a model dedicated to the modification. In order not to interfere with other vehicle electrical equipment, ordinary ignition high-voltage wires will artificially increase the line resistance when manufacturing.

The car audio and car computer will not affect their work due to high-voltage interference, so that daily driving has a sense of security. However, this design also consumes some of the high-pressure ignition energy.

4. Improvement of fuel pressure control valve. The popularity of multi-point EFI engines has brought convenience and benefits to modification. The fuel supercharger is a good configuration for the power increase of the EFI engine.

On the engine fuel supply system, there is a fixed non-adjustable device - the fuel pressure regulator. The OEM sets it at a pressure of more than 5 kg cm from the gasoline pump in the tank.
