    摘要: An engine starting system includes a throttle valve, an alternator, an engine speed sensor and an electronic control unit (ECU). The ECU functionally includes an automatic engine stop controller for automatically stopping the engine by interrupting fuel injection when predefined automatic engine stop conditions are satisfied, and an automatic engine restart controller for automatically restarting the engine when predefined engine restart conditions are satisfied. The automatic engine stop controller sets the quantity of intake air at a level higher than a minimum quantity of intake air necessary for keeping the engine running, decreases the amount of electric power generated by the alternator in an early part of automatic engine stop control operation, and decreases the quantity of intake air and causes the alternator to once decrease the amount of electric power generated thereby at a point in time when the engine speed drops down to a predetermined reference engine speed, and causes the alternator to later increase the amount of electric power generated thereby.

    摘要: A fuel injection control system for a direct injection-spark ignition type of engine forcibly turns off appliances as an external engine load while the engine operates in a stratified charge combustion mode after warming-up so as thereby to fix a quantity of intake air approximately constant and concurrently feedback controls a quantity of fuel injection according to an engine speed so as to bring the engine speed into a specified idling speed. An actual quantitative variation of fuel injection is learned on the basis of a feedback correction value of the quantity of fuel injection for each of predetermined fuel injection timings which are changed from a timing for minimum advance for best torque (MBT) so as to correspond to injection pulse widths within a region adopted for a micro-flow characteristic of the fuel injector.

    摘要: During an air-fuel ratio feedback control based on an oxygen concentration in exhaust gases which converges an air-fuel ratio toward a target ratio suitable for a satisfactory purifying efficiency of a catalyst, the air-fuel ratio is coercively deflected so as to make a fuel mixture richer and leaner alternatively. An extent of deflection of the air-fuel ratio is set larger before the catalyst has not yet been activated sufficiently.

    摘要: An engine starting system for a power train including an engine and an automatic transmission includes an engine stop/restart controller. The automatic transmission having special mode includes first and second planetary gear sets having respective sun gears, a turbine shaft, an output gear, a forward clutch and a 2-4 brake. The forward clutch sets the automatic transmission in a drive condition when engaged and in a neutral condition when disengaged. If the special mode is selected under conditions where the output gear is locked, the sun gear of the first planetary gear set is locked. During execution of automatic engine stop control operation, the engine stop/restart controller causes the automatic transmission to initiate a transfer to the special mode before fuel supply is interrupted and causes the forward clutch to completely engage at a specific point in time after the automatic transmission has completed the transfer to the special mode.
