How to exhaust the car brake system?

Relax the airing screw sleeve l/2-3/4 laps, and then step on the brake pedal 3-4 times continuously (note that the step should be fast and the relaxation should be slow). Fill the pipe with the brake fluid under the action of the main pump and drive out the air in it until the hose does not bubble. In this process, brake fluid should be continuously added to the main pump.

The method of exhausting the brake system is as follows: compressed air method: the air pump pressure is adjusted to about 300KPa (3 kg), use a special cover and air pipe to make a pressurization tool, plug it into the refueling port of the brake storage cylinder, and slowly pressurized the storage cylinder for 3 to 5 seconds;Slowly stop the air, rest for 1 to 2 minutes and pressurized again.

The exhaust principle of the brake pipe is from far to near, that is, the exhaust order is to first discharge the right rear brake wheel cylinder that is the farthest distance from the brake main cylinder, and then arrange the left rear, right front and left front brake cylinder respectively.

ABS pump needs to be exhausted. There are 5 cm long bubbles in the tube, and the brakes are basically ineffective.

Introduction to the composition and function of each component of the exhaust system

The automobile exhaust system is composed of exhaust pipe, catalytic purifier, silencer, tail pipe, etc. 1. The exhaust pipe is the exhaust pipe. Its chassis layout, the length of the pipe, the size of the pipe diameter and the size of the silencer will all affect the flow of the exhaust gas, so as to prevent the mutual interference of the airflow when the adjacent cylinders are discharged.

The automobile exhaust system is generally composed of exhaust manifold, exhaust pipe, catalytic converter, exhaust temperature sensor, silencer and exhaust tail pipe, etc. The automobile exhaust system mainly discharges the exhaust gas discharged from the engine work, while reducing the pollution and noise of the discharged exhaust gas.

Automotive exhaust system function introduction The function of the exhaust system is to collect the exhaust gas from each cylinder of the engine, reduce the exhaust noise, eliminate the flame and sparks in the exhaust gas, safely discharge the exhaust gas into the atmosphere, and control the harmful substances in the exhaust gas.

What are the exhaust systems of cars?

1. The automobile exhaust system is generally composed of exhaust manifold, exhaust pipe, catalytic converter, exhaust temperature sensor, silencer and tail pipe, etc.The automobile exhaust system mainly discharges the exhaust gas from the engine while reducing the pollution and noise of the exhaust gas. Automobile exhaust systems are mainly used for light vehicles, mini cars, buses, motorcycles and other motor vehicles.

2. Tail pipe: The last section connected to the silencer is the tail pipe, which is the last pipe of the exhaust system to lead the exhaust gas out of the car. There are two types of tail pipes: single exhaust and double exhaust. Generally, V-type engines or large-displacement engines adopt double exhaust, and small-displacement vehicles use single-exhaust.

3. The automobile exhaust system is mainly composed of exhaust manifold, exhaust pipe, catalytic purifier, exhaust temperature sensor, silencer, exhaust tail pipe, etc. The automobile exhaust system mainly discharges the exhaust gas discharged by the engine work, while reducing the pollution and noise of the discharged exhaust gas.

4. Automobile exhaust system refers to a system that collects and discharges exhaust gas, which is generally composed of exhaust manifold, exhaust pipe, catalytic converter, exhaust temperature sensor, automobile silencer and exhaust tailpipe, etc.

5. Single exhaust system: In the exhaust stroke of the inline engine, the exhaust gas in the cylinder passes through the exhaust valve and exhaust manifold, and then enters the exhaust pipe, catalytic converter and silencer from the exhaust manifold, and finally into the atmosphere through the exhaust pipe.

6.) Ternary catalytic converter (TWC), mainly installed on gasoline vehicles. 2) Crankcase forced ventilation system (PCV) 3) Exhaust gas recirculation system (EGR) 4) Secondary air injection, mainly used for gasoline vehicles 5) Particle catcher (DPF), mainly used for diesel vehicles.

What is the impact of changing the exhaust of the car on the car?

1. The modification of the exhaust pipe has a great impact on the car. The exhaust pipe of the car is specially designed, and the change has a great impact on the overall layout of the car. It is not recommended to change. Generally, some modification companies can operate it, but it may involve illegal modification, and the later maintenance and repair are also difficult and expensive, so it is not recommended to change.

2. Modification of exhaust has an impact on the car. If the diameter of the exhaust pipe is changed, it will affect the exhaust pressure of the car engine and change the engine power. If the modification is not professional, it may affect the life of the engine.

3. The modification of the exhaust pipe of the car will affect the power and fuel consumption of the car. If the modified exhaust is too smooth, the return pressure in the engine becomes smaller, and the power of the engine is lost after being discharged by the fully burned exhaust gas, the torque will inevitably be affected to a certain extent.

4. If the exhaust is changed, it will have an impact on the torque output of the car. When the exhaust system of the car is modified, there is actually a silencer in it, which is to reduce noise, because ordinary people's ears are very sensitive, just like when they are noisy when they get off the car, they may not be able to hear anything.

5. The modification is simple and does not affect the engine. Some car owners may increase a little psychological horsepower, which is similar to the leakage effect of the exhaust pipe. The truly high-end exhaust module can install an electronic control system in the car or automatically adjust the internal exhaust damper according to the engine speed.
