Abstract

A governor for injection pumps of diesel internal combustion engines in which the injection amount is controlled by the boost pressure. The governor is mounted directly on the crank casing of the internal combustion engine together with an electromagnet which is energized at startup. The governor and the electromagnet transmit thrust and motion to the control rod of the injection pump through the same lever system. The electromagnet is switched in such a way that it overrides the governor during the engine starting process. The lever system is constructed to produce a nonlinear transmission of the movement of the membrane to the control rod.
