Where is the vvt valve of Wuling Hong Guang?

Wuling Hong Guang positive crankcase ventilation valve is close to the rear throttle valve in the engine compartment, between the compressor outlet and the condenser inlet.

The function of waste gas valve is to recycle automobile waste gas into the cylinder for combustion, and this small amount of waste gas 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 working principle of waste gas valve is high pressure gas (gaseous working medium and lubricating oil) from compressor.

After entering the waste gas valve, the guide vane of the waste gas valve flows spirally along the guide vane, and the lubricating oil is separated from the working gas under the action of centrifugal force and gravity, and leaves along the inner wall of the cylinder. The working gas is led out of the waste gas valve from the central pipe through the multi-air baffle. The separated lubricating oil is concentrated in the lower part of the oil separator, which can be discharged regularly or automatically returned to the crankcase of the compressor by using the ball valve.
