A vent valve in a car plays a crucial role in maintaining the proper pressure within the fuel tank. It allows for the release of excess pressure that can build up due to temperature changes or fuel vaporization. When the fuel heats up, it expands, leading to increased pressure. The vent valve opens to equalize this pressure, preventing potential damage to the fuel tank and ensuring safe operation of the vehicle.

Additionally, the vent valve contributes to the vehicle's emission control system. By regulating the flow of fuel vapors, it minimizes the release of harmful gases into the atmosphere. This is especially important in modern vehicles that are designed to meet stringent environmental regulations. By ensuring that vapors are directed back into the fuel system rather than escaping into the air, the vent valve helps enhance fuel efficiency and reduces the overall environmental impact of the vehicle.
