    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: An engine control system for an engine equipped with a swirl control valve which is operative in operation modes different in fuel injection form according to engine operating conditions judges based on a change in an engine operating condition whether a mode shift to one operation mode to another is demanded and controls the swirl control valve so as to attain a target opening for the one engine operation mode while keeping a specific mode shift waiting until the swirl valve opening reaches a limit value permissible in one engine operation mode into which the specific mode shift is made when the swirl control valve is judged to be out of the limit value.

    摘要: An engine control system for controlling operation of an engine of a type injecting fuel directly into a combustion chamber in different injection modes according to engine operating conditions has a map of engine control values with respect to specified engine operating conditions at intersection points of a grid pattern in which engine control values at extreme intersection points adjacent to a boundary between adjacent injection modes is discontinual. The engine control system calculates an engine control value for an engine operating condition by interpolation with the aid of engine control values at the intersection points and determines an engine control value for an engine operating condition at a point closer to the boundary than the extreme intersection point of one injection mode based on engine control values at intersection points of the one injection mode only.

    摘要: An engine control system for an automobile engine of, for example, the type which injects fuel directly into an combustion chamber (16) and executes a fuel-cut control under a specified engine operating condition establishes a stratified charge combustion mode and a homogeneous charge combustion mode selectively according to engine operating conditions following termination of the fuel-cut control and shuts off nearly completely an engine throttle valve (28) during execution of the fuel-cut control and opens the engine throttle valve (28) so as to variably control an amount of intake air passing through an intake passage (24) into the combustion chamber (16) before the stratified charge combustion mode is established following termination of the fuel-cut control.

    摘要: A control device for controlling a direct injection engine provided with an injector for injecting fuel directly into a combustion chamber in a cylinder thereof and a throttle valve is switchable between a stratified charge combustion mode and a uniform charge combustion mode. The control device predicts switching to the uniform charge combustion mode based on a change in the target load Piobj during engine acceleration in the stratified charge combustion mode, and corrects the target load Piobj so that the opening of the throttle valve approaches the opening suited for the uniform charge combustion mode prior to the switching to the uniform charge combustion mode when such combustion mode switching has been predicted. This control device prevents torque shock due to the combustion mode switching during engine acceleration without causing a deterioration in fuel economy or in vehicle acceleration performance.
