Mondeo waste gas valve is broken, will the idle speed become higher?

Mondeo waste gas valve is broken, and the idle speed will become higher. If the waste gas valve is broken, the idle speed will rise and fall, and the car body will feel wobbly. Some of them can't add oil, and the exhaust emission light will be on.

Waste gas valve is also called oil separator pressure control valve. Installed between the compressor outlet and the condenser inlet to improve the heat transfer effect of the condenser and evaporator through isolation.

Working principle of waste gas valve

Oil separator is more important for systems with poor mutual solubility between lubricating oil and working fluid.

The working principle of the waste gas valve is that the high-pressure gas, gaseous working medium and lubricating oil from the compressor enter the guide vane of the waste gas valve and flow spirally along the guide vane, and the lubricating oil is separated from the working medium 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 compressor crankcase by using the floating ball valve.
