Where is the Buick Regal waste gas valve?

The Buick Regal waste gas valve of Pacific Auto Network is installed between the compressor outlet and the condenser inlet. Waste gas valve, also known as oil-gas separator, improves the heat transfer effect in condenser and evaporator through separation. Waste gas valve is a very important component.

If the waste gas valve is damaged, the waste gas recirculation will be abnormal and the fault light will flash.

In addition, if the exhaust gas recirculation valve is improperly closed, part of exhaust gas will enter the air pipe through the exhaust gas recirculation valve when the engine is working, especially at idle speed, and the mixed gas in the engine will be reduced, and the exhaust gas entering the air pipe will combine with the mixed gas in the engine, which will affect the normal work of the engine.

When the engine is idling, it is likely to shake, which will lead to engine flameout in serious cases.

The poor quality of fuel used by the engine for a long time or the aging of the waste valve will lead to the damage of the waste valve.

If you want to check whether the waste gas valve is damaged, you can cut off the fire in a cylinder of the engine. If the engine speed suddenly rises, it means that the EGR valve is not closed correctly. If there is any problem, it should be repaired or replaced in time to avoid affecting the normal use of the car.
