What is the freezing of Chery qq accelerator?

1, the oil-water separator is blocked, so that the exhaust gas in the crankcase cannot be discharged.

2. The exhaust gas introduced into the air inlet through egr system or pcv system has a high temperature. When the high-temperature exhaust gas approaches the throttle valve with lower temperature, the gaseous water carried in the exhaust gas will condense into liquid water. Under the extremely cold winter conditions in the north, the air temperature entering the air inlet is very low. When the driver releases the accelerator pedal during driving, the flow rate of low-temperature air will become very fast when the throttle is only opened with a small gap. Under the dual action of low temperature and high flow rate of cold air, condensed water is likely to freeze instantly, forming a frozen throttle.
