Automobile exhaust system refers to the system that collects and discharges exhaust gas. It is generally composed of exhaust manifold, exhaust pipe, catalytic converter, exhaust temperature sensor, automobile muffler and exhaust tail pipe. Some car owners often refit to a certain extent. What are the hazards of remote control exhaust valve? Can the remote exhaust valve be closed for a long time? This issue of like valve answers for you one by one!
1、 What are the hazards of remote control exhaust valve
The remote control exhaust valve will not hurt the car. Refitting the remote control valve is not harmful to the exhaust. The opening should not be in front of the oxygen sensor, but behind the sensor, otherwise the engine data will change. Automobile exhaust system refers to the system that collects and discharges exhaust gas. It is generally composed of exhaust manifold, exhaust pipe, catalytic converter, exhaust temperature sensor, automobile muffler and exhaust tail pipe. In the whole exhaust emission process, the exhaust manifold is encountered earlier. The exhaust manifold is to avoid the mutual interference of exhaust between cylinders and make the exhaust gas completely discharged out of the pipe as much as possible. The middle section of the exhaust pipe only needs to guide the exhaust gas from the exhaust manifold to the exhaust tailpipe.
Modification of remote control valve is harmless to exhaust. However, it should be noted that the opening should not be in front of the oxygen sensor, but behind the sensor, otherwise the engine data will change.
The specific situation needs to be analyzed. It depends on whether to change the remote control exhaust valve only to the tail end or the middle end and the whole section. If it is only the tail end, the power is the same as the original on the premise that the valve is fully open, but if the part is closed, it will affect the original power.
2、 Can the remote exhaust valve be closed for a long time
The long-term closure of automobile exhaust valve will have an impact on the exhaust valve, and the consequence is that the exhaust valve cannot be opened. It causes the pressure in the engine to rise and the work is unstable.
Opening and closing conditions of BMW exhaust valve (take BMW 5 series as an example): the exhaust of BMW is discharged from the left and closed from the right. The exhaust valve on the right can be opened by fixing it with a circle of iron wire, or it will open automatically when the speed reaches about 300.
The commonly used shut-off valve has no effect on the engine. The function of the exhaust valve is to stabilize the propulsion pressure of the turbocharging system to protect the engine and turbocharger. The exhaust valve is controlled by the transmission device of the exhaust valve, and the rotating device is controlled by the pressure of the intake manifold.
1. In the exhaust state, the pontoon pulls down one end of the lever due to gravity, and the lever is in an inclined state at this time;
2. There is a gap in the contact part between the lever and the exhaust hole, and the air is discharged from the exhaust hole through this gap;
3. With the discharge of air, the water level rises, the pontoon floats upward under the buoyancy of water, and the sealing end face on the lever gradually presses on the exhaust hole until the whole exhaust hole is completely blocked; The exhaust valve is now completely closed.
