Abstract
A method and apparatus for braking a multicylinder diesel engine. Some compressed gases are released from each engine cylinder near top dead center of each compression stroke on each cycle of the engine by forcing open the exhaust valve with a slave piston assembly of a two-stage master and slave cylinder combination. The slave piston assembly is moved by a master piston assembly which operatively engages an engine component which moves prior to top dead center of each compression stroke. The ratio of the area of the master piston assembly to the slave piston assembly is then increased and the exhaust valve is then opened to a preset fully cracked open position during a second stage of the master and slave cylinder combination. Loading on the engine component is reduced during the first stage and the rate of opening the exhaust valve is increased during the second stage when the force required to further open the exhaust valve has been reduced.
