ABSTRACT:
An apparatus for controlling fuel injection timing in a diesel engine includes a piston activated by supplied pressure proportional to engine speed to advance the injection timing of the fuel injection pump in accordance with engine operating speed. In accordance with the invention, the injection timing control apparatus is provided with an adjusting mechanism which responds to a supplied indication of engine temperature for advancing the injection timing when the engine is cold and retarding the injection timing when the engine is at normal operating temperature. In a preferred embodiment, the indication of engine temperature is fluid pressure which is controlled by a valve and acts on an adjusting member to increase the tension on the piston return spring when the engine is at operating temperature.
