Abstract
Hydro-mechanical brake timing means are provided to control the timing of an engine braking system of the gas compression type for an internal combustion engine wherein the engine braking system includes a hydro-mechanical mechanism which opens the exhaust valve near the top of the compression stroke of the engine so that the energy absorbed by the engine during the compression stroke is not returned to the engine during the expansion stroke. In accordance with the present invention, hydro-mechanical means are provided in the exhaust valve actuating mechanism whereby the clearance in that mechanism is reduced to a value which maximizes the retarding power developed by the engine whenever the engine brake is activated.
