PURPOSE:To smooth the rising of engine rotations by setting the ignition timing to a fixed spark advance angle during idling for a predetermined time when starting a car then by switching it to a basic ignition timing in accordance with the engine load and engine speed. CONSTITUTION:When the idle switch of a throttle sensor is made on, the idle judgment flag is made ''1'' at a step 101. When the idle switch is made off and the idle judgment flag is set at ''1'', a computer judges that a car is starting and proceeds to a step 104. At steps 106, 107, the ignition timing is set to a fixed spark advance angle thetaidle during idling for a predetermined time. Then at steps 106, 108, the ignition timing is set to a basic ignition timing thetaBSE. Thereby, the rising of engine rotations can be smoothed. |
