Abstract
A method of engine compression release braking with avoidance of turbine overspeed is disclosed. Initially, an electronic control module determines whether a turbine overspeed condition is present. If an overspeed condition is present, then the blow down timing of an engine compression release braking event is advanced. The present invention is particularly applicable to preventing turbine overspeed for vehicles operating at higher altitudes while compression braking.
