Description

What does an exhaust gas flap do?

This exhaust gas flap functions as a critical component of the engine braking system, working to regulate exhaust gas outflow. By restricting the flow of gases within the exhaust line, it increases in-cylinder back-pressure, which assists in slowing the vehicle down effectively and reducing the load on service brakes.
