Chevy Trailblazer EGR Valve

The manufacturers of the Chevrolet Trailblazer have installed wonderful mechanisms to assure its client that when they acquire this type of vehicle, they are not contributing much to air pollution. With its well engineered exhaust system, including the catalytic converter, you are sure to abide by the rules and regulations implemented by certain concerned environmental agencies. If you are planning to own a car, but you are worried of whether the car you are going to choose will not meet the standards of these agencies, then you better start looking for vehicles with a high green rating. With this predicament, better go with a Chevrolet Trailblazer.

The Chevrolet Trailblazer is equipped with an EGR valve. A Chevrolet Trailblazer EGR valve is an apparatus that controls the main emissions in the gas recirculation system in the exhaust system. It is located at the intake manifold and unlocks a tiny passageway between the exhaust and the intake manifold to allow the flow of a certain amount of exhaust back to the engine. Through this, the combustion temperature will be minimized and the formation of nitrogen oxides is controlled. The application of vacuum to the control diaphragm opens the EGR valve. Back pressure of exhaust is also sometimes needed before the valve shall open.

Modern EGR valves are electronically operated. The Chevrolet Trailblazer EGR valve also has a mechanism to close itself while the engine is cold because it is not performing any work. It should only be opened when the engine is already warm and running. A disconnected or shut EGR valve means that higher NOX emissions and detonation will soon follow. It should always be in tip top shape because if it sticks in the open position even though it should be closed or vice versa, it will leak like a vacuum and thus could result to being idle and probable stalling.
