A device for detecting engine brake.

摘要

A device for detecting engine brake, the device including a memory for storing the rotating speeds of the engine corresponding to the degrees of opening the throttle valve, a detector of the degree of opening the throttle, a detector of the actual rotating speeds of the engine, and a device of discerning that the engine is an engine brake state when the actual speeds of the engine corresponding to the actual degrees of opening the throttle exceed the speeds of the engine stored in the memory.
