What Happens If the Exhaust Brake Is Always On?

[RiverLee]

The exhaust brake of a car should not be left on continuously, and long-term use is not recommended. Prolonged use of the exhaust brake can cause significant damage to the engine and also has a considerable impact on the valves. Here is some knowledge about exhaust brakes: 1. The principle of exhaust braking: Exhaust braking transforms the engine, originally a power output device, into an air compressor, turning it into a power-consuming device. 2. The concept of exhaust braking: Exhaust braking involves installing a regulating valve on the engine's exhaust pipe. By closing this valve, the pressure formed by the exhaust is increased, and the resulting negative pressure is used to obtain braking force. The exhaust brake is generally activated by a manual switch. To prevent the engine from stalling when stopping and to avoid exhaust braking during fuel injection, the exhaust brake is automatically released when the accelerator pedal or clutch pedal is pressed.
