<p><P>PROBLEM TO BE SOLVED: To provide an engine control device without generating uncomfortable feeling to the operator at the time of changing an ignition timing in a normal running state in an engine comprising an electronically-controlled throttle. <P>SOLUTION: The device comprises a throttle sensor 15 for sensing the throttle opening sensing value, a crank angle sensor 17 for sensing the number of rotations of a crankshaft 9, a memory 21 for storing an optimum ignition timing and an ordinary ignition timing set according to the throttle opening degree and the number of rotations, and an ECU 20 for producing a command value for the engine ignition timing and throttle opening degree. The ECU 20 makes the ignition timing command value closer to the target value with the optimum ignition timing corresponding to the throttle opening degree and number of rotations sensed at the starting of the regular operation state regarded as an ignition timing target value, and it makes the throttle opening degree command value smaller for maintaining the regular operation state by restraining the output rise due to change of the ignition timing. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
