    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： A controller of a vehicle internal combustion engine that is automatically stopped and restarted under a prescribed condition related to operation of the vehicle is disclosed. The engine includes an output shaft, a starter constantly meshed with the output shaft, and a throttle valve regulating the intake air amount supplied to the engine. After the engine has been subjected to an automatic stopping procedure, the controller restarts the engine when a restarting condition is met, and the controller uses the starter to restart the engine if the engine speed is in such a predetermined range that autonomous operation of the engine cannot be restored. The controller predicts, as a predicted air amount, the amount of air drawn into the cylinder of the engine after the restarting condition is met. The controller reduces an engine start fuel injection amount, which is calculated when the starter is used, in correspondence with the predicted air amount.

    摘要： A controller (40) of a vehicle internal combustion engine (10) that is automatically stopped and restarted under a prescribed condition related to operation of the vehicle is disclosed. The engine (10) includes an output shaft (11), a starter (20) constantly meshed with the output shaft (11), and a throttle valve (12) regulating the intake air amount supplied to the engine (10). After the engine (10) has been subjected to an automatic stopping procedure, the controller (40) restarts the engine (10) when a restarting condition is met, and the controller (40) uses the starter (20) to restart the engine (10) if the engine speed is in such a predetermined range that autonomous operation of the engine (10) cannot be restored. The controller (40) temporarily opens the throttle valve (12) on the condition that the engine speed at the time when the restarting condition is met is not zero and is in the predetermined range.

    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.

    摘要： An ECU 30 executes ignition timing retarding control for retarding ignition timing in relation to idling ignition timing at the start of an engine. Also, during the execution of the ignition timing retarding control, on condition that an engine speed NE becomes less than or equal to an idling target speed NEidle and the difference ΔNE of these values becomes greater than or equal to a predetermined value ΔNEstpx, the ECU 30 stops the ignition timing retarding control and executes an ignition timing advancing control for advancing the ignition timing. When a coolant temperature THW is higher than or equal to a predetermined temperature THW1, the ECU 30 stops fuel injection on condition that the engine speed NE becomes greater than or equal to a predetermined speed NEcut. Further, if the coolant temperature THW is higher than or equal to the predetermined temperature THW1, the ECU 30 sets the predetermined value ΔNEstpx for stopping the ignition timing retarding control to a larger value than in a case where the engine temperature THW is lower than the predetermined temperature THW1.
