How to Use Exhaust Brake?

[DelilahMarie]

Exhaust brake usage method: When the accelerator pedal is at zero position and the fuel injector stops injecting fuel, the exhaust brake will automatically turn off if the accelerator pedal or clutch pedal is pressed. This prevents the engine from stalling when stopping and ensures the exhaust brake does not activate during fuel injection. The exhaust brake is widely used in large diesel vehicles. A regulating valve is installed on the engine exhaust pipe, and by closing this valve, the pressure during the exhaust stroke is increased, utilizing the generated negative pressure to obtain braking force. The regulating valve is usually driven by a control mechanism using compressed air or vacuum, and in most cases, it shares the same power source as the main brake. The exhaust brake is generally activated by a manual switch. To prevent the engine from stalling when stopping and to avoid exhaust brake activation during fuel injection, pressing the accelerator pedal or clutch pedal will automatically release the exhaust brake.
