Abstract

PURPOSE: To maintain a stable revolving condition with high thermal efficiency at an idling time by controlling revolution of an engine at the fast idling and idling to be expected numbers of revolution with an engine temperature and an atmospheric temperature as functions.
CONSTITUTION: Numbers of revolution at the fast idling time and idling time are controlled to be an expected number of revolution of which functions are an engine temperature and an atmospheric temperature, and they are also controlled to feed fuel rate and air rate of which thermal efficiencies are at the maximum. For example, analog signals from a sensor 124 to detect suction air rate, a sensor 156 to detect temperature of engine cooling water, a pulse signal from a crank angle sensor 171, and others are input to a control circuit 170 with a microcomputer. Then, by an output from the control circuit 170 operated as explained above, a fuel injector 112 and an ignition coil 158 are driven.
