INFINITELY VARIABLE ENGINE COMPRESSION BREAKING CONTROL AND METHOD

摘要

A control for operating an engine (30) in a braking mode of operation includes an actuator (110) engageable with an engine exhaust valve (40). A braking magnitude is selected from a continuous range of braking magnitudes between minimum and maximum levels and turn-on and turn-off points for the actuator (110) are established from the selected braking magnitude. The actuator (110) is operated in accordance with the turn-on and turn-off points to cause the engine (30) to develop the selected braking magnitude.
