How to deal with the oil from the valve cover to the throttle hose of Wuling truck 1.8 displacement?

Wuling truck 1.8 displacement hose string from the valve cover to the throttle valve is treated by opening the valve cover to check and clean the oil tank or replacing the gasket. The function of the valve is specially responsible for inputting air into the engine and discharging exhaust gas after combustion. From the engine structure, it is divided into intake valve and exhaust valve.

The function of the intake valve is to draw air into the engine and mix it with fuel for combustion; The function of the exhaust valve is to exhaust the exhaust gas after combustion and dissipate heat.

Weight reduction and consumption reduction of valve cover

Reducing vehicle self-weight is one of the important measures to improve fuel economy. For cars, the dead weight is reduced by 65,438+00%, and the fuel consumption can be reduced by 8% ~ 65,438+00%. For a truck, every decrease in its own weight of 1 000kg can reduce its fuel consumption by 6%~7% and increase its payload. Compared with metal valve cover, SMC valve cover reduces the weight by 25%~34%, making the engine lighter and more fuel efficient.

Reducing engine noise is the key to reduce engine noise. The engine valve cover is directly connected with the engine, which bears and transmits the vibration and noise from the engine. Therefore, improving the sound insulation and absorption effect of valve cover is an effective means to reduce noise pollution.

Compared with metal, plastic has better sound attenuation (the sound absorption coefficient of SMC is 0.2 1, and that of felt is 0.24) and damping.
