An exhaust valve in a car is a critical component of the engine's combustion system. It plays a crucial role in managing the flow of exhaust gases out of the engine cylinder. The exhaust valve is located in the cylinder head and is responsible for opening and closing at specific times during the engine's combustion cycle.

When the piston moves down in the cylinder during the exhaust stroke, the exhaust valve opens to allow the burned gases to escape from the combustion chamber. This process removes harmful byproducts produced during combustion, such as carbon monoxide and nitrogen oxides, ensuring that the engine operates efficiently and reduces emissions. After the exhaust stroke, the exhaust valve closes tightly to create a proper seal, preventing any fresh air and fuel mixture from escaping from the cylinder.
