Modern medium duty diesel engines are all developed with engine brake as a standard feature. The main purpose of the engine brake in an automobile is to deliver high vehicle retardation, engine safety and longer foundation brake life. It allows the driver to possess complete control of the vehicle while driving downhill without the need for frequent usage of foundation brakes. This intern prevents the engine revs from exceeding the safe limit thereby protecting the engine. It also help reduce the fuel consumption by avoiding unnecessary braking and thereby necessitating to accelerate again. Typically the braking power in a diesel engine is generated by closing the exhaust system partially or completely. This would increase the back pressure in the exhaust circuit and thereby increase the piston work of the engine. This negative work is used for vehicle braking. This system is called as “Exhaust brake”.
