He told me that the purge valve is a part of the emissions control system in a car. It helps to reduce emissions by recycling vapors from the fuel tank. These vapors are then burned in the engine, which helps to reduce pollution.
How Does a Purge Valve Work?
The purge valve is located on the engine intake manifold. It is a small, plastic valve that opens and closes to allow vapors from the fuel tank to enter the engine.
When the engine is running, the vacuum in the intake manifold draws vapors from the fuel tank through the purge valve. These vapors are then mixed with air and burned in the engine.

If the purge valve fails, it can cause a number of problems. These problems can include:
- Increased emissions

If you suspect that your purge valve is failing, it is important to have it checked by a qualified mechanic.
