The main function of the waste gas valve is to regulate the exhaust gas circulation inside the engine and reduce the pollution of the exhaust gas to the environment. When the engine is working, the waste gas valve reintroduces part of the exhaust gas through the intake system to the combustion chamber for secondary combustion, thereby reducing the direct emission of exhaust gas into the atmosphere. The working principle of the waste gas valve includes the use of the engine intake air to produce the exhaust gas into the intake system, and then into the combustion chamber for secondary combustion
Installation and maintenance precautions :
Installation procedure : To replace the waste air valve cover, remove the plastic parts and plastic clips from the cylinder head near the air filter. Remove lightly with a small crowbar. When installing the cover, ensure that the cover is pressed down to ensure that it is properly installed
maintenance precautions : Regularly check the working status of the waste air valve, which can be preliminarily checked by observing whether the oil cap has suction and whether the engine jitter when pulling out the oil gauge. If the negative pressure is abnormal, you are advised to use a negative pressure meter for accurate detection. In addition, keep the engine inside clean, avoid the accumulation of carbon and sludge, can effectively extend the service life of waste gas valve
