ABSTRACT:
A fuel injection rate limiting device for diesel engine aimed at improving engine performance on starting as well as in operation under overload through impartation of an increased tenacity, wherein a limiter means is provided to check a governor lever to thereby limit the fuel injection rate under the full-load condition but at the same time the governor lever is allowed to continue shifting within reason and gradually against a torque spring in such direction as to increase the fuel injection rate so that the fuel injection rate is gradually increased as the engine speed (rpm.) falls under overload. Moreover, on starting of the engine, the governor lever is caused to shift extensively against the torque spring as well as the starting spring in the fuel injection rate increasing direction for improvement of the engine's starting performance. It is also aimed at enabling adjustment with a high precision of the extent of increase of fuel injection rate with engine running under overload as well as on starting and this object is accomplished by providing separate checking means for individual limiting of the retreating strokes of the torque spring and starting spring which are adjustable, again individually, by the respective adjusting screws.
