Abstract
A fuel injection timing apparatus comprises a pair of weights which rotate synchronously with an engine, so that adjustment of the injection timing of a fuel injection pump is carried out by means of the movement of these weights against the biasing forces of springs. This apparatus further comprises stopper members disposed at positions corresponding to both opposed ends of the weights to be movable in the direction perpendicular to the direction of the movement of the weights, and temperature-sensitive driving devices for moving the stopper members in accordance with ambient temperatures, which are arranged to operate such that, when the engine is started, the stopper members are made to project between the pair of weights in accordance with the ambient temperatures to restrain the weights which tend to return to their initial positions by the biasing forces of the springs.
