Abstract
An on/off compression braking system is provided which when actuated controllably opens one inlet valve and one outlet valve in response to the actuation of the injector unit rocker arm and deactivates the exhaust valve rocker arm. This braking system thereby is useful on four cycle engines and is of a construction which eliminates elements of heretofore utilized compression braking systems and provides a four cycle engine with a two cycle compression braking system.
