<P>PROBLEM TO BE SOLVED: To improve convergence to a target engine operation point, when the operation point of an engine changes in torque base control, by improving control responsiveness and control stability of suction air volume control, in a control device of the engine. <P>SOLUTION: This control device of the engine includes: a target ignition timing arithmetic operation means 6A for arithmetically operating the target ignition timing for calculating the air volume to be introduced into a cylinder 19 of the engine 10; a heat efficiency arithmetic operation means 7 for arithmetically operating heat efficiency of the engine 10 on the basis of the target ignition timing; and a target air volume arithmetic operation means 4 for arithmetically operating the target air volume, which is a target value of the air volume to be introduced into the cylinder 19, on the basis of the heat efficiency. The target ignition timing arithmetic operation means 6A arithmetically operates the target ignition timing in the current arithmetic operation period, on the basis of the target air volume arithmetically operated by the past arithmetic operation period in the target air volume arithmetic operation means 4. <P>COPYRIGHT: (C)2013,JPO&INPIT |
