Abstract: PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine which enables the correction amount of the intake-air volume after the startup of an internal combustion engine to be set at a more appropriate value.
SOLUTION: When the internal combustion engine is running at idle after the startup, the correction amount of the intake-air volume is calculated based on the target value of the intake-air volume and the measurement value of the intake-air volume (steps S3, S7). Then the intake-air volume is controlled by the control device of the internal combustion engine based on the calculated correction amount. The intake-air volume is controlled by the control device of the internal combustion engine based on the control input of idle speed control containing the degree of opening of a throttle or the degree of opening of an idle speed control valve corresponding with the target value of the intake-air volume and on the control input of idle speed control at the time when the correction amount is calculated (a step S11).

Abstract: PROBLEM TO BE SOLVED: To stabilize the idle rotating state of an engine in an idling cruising when warmup operation is not completed. SOLUTION: When a vessel is allowed to cruise and a throttle is turned off, the opening of a secondary air valve is controlled based on a reference engine idling rotational speed which reduces at a specified reduction rate with an elapsed time after the engine is started until the warmup operation is completed. When an input engine idle rotational speed by an operator is larger than the reference engine idle rotational speed, the opening of the secondary air valve is controlled based on the input engine idling rotational speed. When the reference engine idling rotational speed becomes a specified engine idling rotational speed, the warmup operation is considered to be completed. When the engine is stopped or the engine rotational speed exceeds a specified value, the input engine idle rotational speed is reset. COPYRIGHT: (C)2005,JPO&NCIPI
