摘要:
In a spark ignition type internal combustion engine (11), automatic stoppage and automatic startup are executed under predetermined conditions, and a fuel cut is executed when an engine rotational speed exceeds a reference rotational speed that is higher than a target idle rotational speed (Ni) at the beginning of the automatic startup. An electronic control apparatus executes ignition timing variable control during startup of the internal combustion engine (11) such that an ignition timing of the internal combustion engine (11) is retarded when the engine rotational speed is increasing and advanced when the engine rotational speed is decreasing. Further, the electronic control apparatus prohibits the ignition timing variable control for a predetermined time following the beginning of startup of the internal combustion engine (11), and the predetermined time during which the ignition timing variable control is prohibited is set to be longer during automatic startup of the internal combustion engine than during manual startup.
摘要:
When the internal combustion engine (11) is stopped, the ECU (41) controls the load torque of the alternator (34) so that the engine rotational speed (NE) coincides with the target engine rotational speed. By so doing, the ECU (41) executes stop position control in which the internal combustion engine (11) is stopped so that the crank angle θ at the time of engine stop stops within the target crank angle range. While the stop position control is being executed, the ECU (41) calculates a required load torque necessary to make the engine rotational speed (NE) coincide with the target engine rotational speed (NEtg), and then compares the required load torque with the maximum load torque of the alternator (34) at the engine rotational speed (NE) at that time. Then, when the required load torque is larger than the maximum load torque, the ECU (41) ends the stop position control.

Air amount adding control, which adds air upstream of a throttle valve to air in an intake passage downstream of the throttle valve by opening the throttle valve is prohibited if the engine speed is higher than a predetermined speed when an engine (1) does not stop even after a predetermined period of time has passed even though there is an engine-stop command from a clutch pedal being released (i.e., operated OFF) (i.e., ceo-run mode: Mode 2) when the engine has finished warming up, and there is an engine-restart command from the clutch pedal being depressed (i.e., operated ON).

摘要:
A controller for a vehicle internal combustion engine (10) capable of being automatically stopped and restarted. When a restarting condition is satisfied after an automatic stopping condition is satisfied, the controller restarts the engine (10). When the engine (10) restarts, the controller executes fuel cutoff if the engine speed becomes higher than or equal to a fuel cutoff permission speed. The controller prohibits execution of the fuel cutoff when a manual transmission (32) is shifted to a gear other than neutral after the restarting condition is satisfied.
