Method of controlling international combustion engine

Abstract

Abstract PURPOSE: To control rack position of a fuel injection pump for setting the rotation of an internal combustion engine within a stable limit and the output torque within load torque by providing a circuit for generating rack displacement target value with the input of rotational frequency deviation of the internal combustion engine. CONSTITUTION: Deviation ΔN of rotational frequency of an internal combustion engine as difference between target rotational frequency Nr and output one N is converted into target value M of rack displacement by a circuit 11 for generating rack displacement target value. A rack drive means 12 is operated according to difference ΔY between the value M and rack displacement Y to control an injection pump 5. While the rack displacement target value M is set smaller than the stable limit of rotational property of the internal combustion engine by a control 10, the output torque of the engine is set smaller than the minimum value of torque reaction of load. Thus, power caused by inertial load of external force can be recovered. COPYRIGHT: (C)1982,JPO&Japio
