What are the symptoms of the old Jetta waste gas valve broken?

If the exhaust valve of Pacific Auto Network is damaged, it will lose the function of oil-gas separation, and at the same time, it may inhale engine oil, which will make the engine oil enter the combustion chamber, leading to the phenomenon of blue smoke when burning oil. At the same time, after the automobile waste valve is damaged, it will be impossible to control the waste gas circulation, and too much waste gas will participate in the recirculation, which will affect the concentration of mixed gas. The car may have difficulties in starting, engine jitter, unstable idle speed and weak acceleration, thus affecting the performance of the engine.

Automobile waste gas valve, also known as oil-gas separator/pressure control valve, is installed between the compressor outlet and the condenser inlet, which improves the heat transfer effect in the condenser and evaporator through separation, which is very important for the system with poor mutual solubility of lubricating oil and working medium.

The function of the automobile exhaust valve is to make the automobile exhaust gas enter the cylinder for re-combustion, and this small amount of exhaust gas reduces the combustion temperature of the cylinder and the NOX content in the exhaust gas. However, the automobile has been used for a long time, and the waste gas valve will inevitably fail or be damaged. Once the automobile exhaust valve is damaged, it will affect the performance of the engine, causing the automobile to burn oil and the exhaust pipe to emit blue smoke, which will affect the normal use of the automobile.
