Abstract
A system and method for controlling combustion engine compression braking having the variable timing of the dwell period of at least one exhaust valve by an electronic control module within each one of the engine cylinders during a braking event as well as the variable timing of the commencement or onset of the braking event. The system and method thus facilitate the proper performance of the braking event as a function of engine speed and prevents interference or physical impact with the cam driving elements used for achieving the normal or regular exhaust valve event.
