Function of automobile exhaust valve
Is to recycle the automobile exhaust into the cylinder for combustion. Automobile exhaust valve, also known as oil-gas separator and oil-water separator. That is, when the combustion chamber of the cylinder is ignited to do work, gas will string into the crankcase from the side wall of the piston, and more and more gas will be discharged. In order to prevent the air pressure from being too high and polluting the air, this gas will be reused from the intake pipe. Some automobile air inlets are in front of the throttle, and some automobile air inlets are on the intake manifold behind the throttle.
A small amount of automobile exhaust reduces the temperature in the cylinder during combustion. Because NOX is generated under the condition of high temperature and oxygen enrichment, the generation of NOX is suppressed, thus reducing the NOX content in exhaust gas. The engine control computer controls the solenoid valve to open in time according to the engine speed, load, temperature, intake flow and exhaust temperature. The vacuum degree of the intake pipe enters the EGR valve vacuum membrane chamber through the solenoid valve, and the diaphragm rod opens the EGR valve. A small amount of exhaust gas enters the intake system through EGR valve, and enters the cylinder to participate in combustion after mixing with mixed gas.
