Location of Buick Regal waste gas valve (what are the characteristics of the new Regal waste gas valve broken)

After the Regal waste gas valve is damaged, it will be difficult to start, the engine will shake, the idle speed will be unstable and the acceleration will be weak, which will affect the engine performance. The exhaust valve is very important for the system with poor miscibility between lubricating oil and working fluid. Once damaged, it will affect the performance of the engine, leading to engine oil burning and blue smoke from the exhaust pipe, which will affect the normal use of the car.

The exhaust valve, also known as oil-gas separator and pressure control valve, is installed between the compressor outlet and the condenser inlet to improve the heat transfer effect in the condenser and evaporator by separating oil and gas. The function of exhaust valve is to make automobile exhaust gas enter the cylinder for circular combustion, which reduces the combustion temperature of the cylinder and the NOX content in the exhaust gas. However, the exhaust valve will inevitably fail or be damaged after the car is used for a long time.

Damage characteristics of exhaust valve

1. After the waste gas valve is damaged, it will be impossible to control the waste gas circulation, and excessive waste gas will participate in the recovery, which will affect the concentration of mixed gas. The automobile may have problems such as starting difficulty, engine jitter, unstable idle speed and weak acceleration, which affect the engine performance;

2. The wastegate valve plays the role of oil-gas separation. During normal operation, only exhaust gas is inhaled, and engine oil is not inhaled. When the wastegate valve is damaged, it will lose its oil-gas separation function, and engine oil may be inhaled when inhaling, which will cause the engine oil to enter the combustion chamber, causing engine oil burning and blue smoke.
