Emissions Control Gas Vent Valve is a Necessary Part of Your Car

Each part of your automobile is controlled by a different part, yet they all work together to keep the vehicle operating efficiently. The automobile technology has made much advancement through the years. These advancements have improved the efficiency of the automobile while at the same time being less harmful to our environment. Years ago, when the automobile was first invented, it was such a step forward for the world that problems that it caused to our environment were not taken into consideration. Today, with the constant struggle to clean the atmosphere of harmful vapor and gases, vehicles and large machinery are being made with preventative measures, such as the emissions control gas vent valve.

Emissions control gas vent valve is just as the name states. It’s a valve that helps control the emissions of gas from escaping into the atmosphere. Whereas years ago you could drive behind a vehicle and see the fumes and gases coming out the tailpipe, vehicles are made with preventative parts such as the emissions control gas vent valve. The emissions gases are contained in the vapor canister and the emissions control gas vent valve is the valve on the vapor canister, which allows the pollution gases to be vented. Vapor canister may also be called emission gases canister. Emissions control gas vent valve is one of the parts that have been developed by the Evaporative Emission Control System.

Evaporative Emission Control System (EECS) was started to help stop gases and vapors from escaping from our fuel tanks and going into the atmosphere. Automobiles have fuel tank vapors in them at all times, even when the car is not running. However, if the car isn’t running, they’re not getting into our atmosphere polluting the environment. Thanks to the EECS, these vapors are stored in a charcoal canister, which is located in the left rear wheel well. The canister stores these gasoline vapors from the gas tank until they can be purged and safely burned by the engine. In some methods of purging, this process is taken care of by the emissions control gas vent valve.

The purge cycle of the charcoal canister can be operated by a throttle position or by the use of the emissions control gas vent valve. If the basic throttle position is used, the canister and a ported vacuum source are connected by a vacuum line. The minute the throttle is in an above idle position, the vapors are moved to the throttle body and fresh air is sucked into the canister bottom. The emissions control gas vent valve is kept in a throttle position by help from the vacuum valve. The vacuum in the throttle body opens the diaphragm valve and allows vapors and air to be sucked into the intake manifold. The more the throttle can be opened, the more air that can be purged. The charcoal canister valve can also have a purge cycle that’s controlled by the solenoid valve stored on the canister. This provides a quick exchange of vapors for fresh air.
