Engine brake valve

What is an engine brake valve and what is its function?

An engine brake valve is a component of the truck engine braking system. The engine brake valve regulates the exhaust gas flow or compression pressure inside the engine, creating additional resistance that slows the vehicle down without relying solely on the wheel brakes. This reduces wear on the standard braking system and increases safety.

How does an engine brake valve work in a truck?

When the engine brake is activated, the engine brake valve closes or restricts the passage of exhaust gases. This creates back pressure in the engine, generating a braking effect. Control can be pneumatic or electronic, depending on the engine type.
