    Abstract: In a fuel injection control system for an internal combustion engine, a fuel atomization device is provided to atomize fuel injected at the time of engine starting. The fuel atomization device may be a type which increases fuel pressure to a higher value at the time of engine starting than after the engine starting. Alternatively, the fuel atomization device may be a type which supplies assist air to the injected fuel. An intake valve is opened for a longer period at the time of engine starting than after the engine starting, so that more fuel may be supplied to an engine cylinder. A fuel leakage which may occur during engine stop is estimated, and the amount of fuel to be injected at the time of next engine starting after the engine stop is corrected by the estimated amount of fuel leakage. Fuel injection timing at the time of engine starting is retarded relative to that of post-engine starting. The amount of injected fuel adhered to an intake port and not supplied into an engine cylinder after the closing of the intake valve is estimated, and the amount of fuel to be injected next is corrected thereby.

    Abstract: In a fuel injection control for engines, a basic transient correction coefficient is calculated to be used for correcting a basic fuel injection amount calculated based on intake air pressure. This transient correction coefficient is itself corrected by a further correction coefficient which corresponds to a fuel injection timing variable so as to overlap with the opening of an intake valve. The basic fuel injection amount is then corrected by the corrected transient correction coefficient to determine a final fuel injection amount. Thus, air-fuel mixture is controlled to a desired air-fuel ratio even when the engine is in a transient condition, thereby improving drivability and exhaust emissions.

    Abstract: A control unit uses upper and lower limit guard values to limit a power generation quantity of a power generator and thereby to maintain the current combustion mode during power generation of the power generator. The control unit computes a remaining electric charge of a battery. When the remaining electric charge drops to a predetermined value or below, the control unit cancels a combustion mode maintaining operation, which maintains the current combustion mode, is cancelled, so that priority is given to the power generation of the power generator to recover the remaining electric charge of the battery. Also, when an electric power consumption in a vehicle is equal to or greater than a predetermined value, the combustion mode maintaining operation is cancelled, and the power generation quantity of the power generator is controlled in a manner that does not cause overdischarge of the battery.

    Abstract: Intake pressure is estimated for an engine load using an averaged accelerator depression position derived by smoothing sensed changes in accelerator depression position. Throttle valve opening angle is controlled based on the thus estimated intake pressure. A corresponding fuel injection value is calculated and supplied to the engine thus matching the estimated air and fuel amounts. Thus, deviation of the air-fuel mixture from a stoichiometric ratio can be reduced even with rapid and complicated accelerator operations.

    Abstract: A fuel injection control system for an engine enhances efficiency for charging suctioned air into a cylinder stabilizes a fuel combustion state. An engine intake pipe is provided with an air-assisted injector. Fuel injected by the injector flows into a combustion chamber within the cylinder via an intake valve. An ECU controls the injector drive so that injected fuel flows into the cylinder about 1/3 of the time at the beginning of the valve opening period. This arrangement allows a large amount of fuel supplied into the cylinder to be vaporized quickly and completely before the intake value is closed. At this time, because temperature of air drops due to heat of vaporization of the fuel, weight (density) of air suctioned into the cylinder per unit volume increases, thus enhancing the charging efficiency of suctioned air.

    Abstract: For regenerative generation at deceleration of a vehicle, a regenerative control apparatus for vehicles equipped with a lock-up clutch comprises a control unit for controlling rotary electric machine and the lock-up clutch. When the clutch is in a complete disengagement state or a slipping state at deceleration, the control unit controls the rotary electric machine to execute regenerative generation at a partial generation level lower than a regenerative generation level in a complete engagement state. When the clutch is in a complete engagement state at regenerative generation, the control unit controls the clutch so that the coupling state is transferred to a slipping state or a complete disengagement state when the number of revolutions having correlation to engine speed becomes lower than a predetermined threshold. Thus, recovering efficiency of the regenerative braking energy can be enhanced, while suppressing engine stall due to drastic increase of engine load torque.
