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： 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： 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 intake system for a multi-cylinder internal combustion engine having an intake manifold that is made up of a common intake passage and separate intake passages that branch off from the common intake passage and connect to intake ports of the engine cylinders. An upstream throttle valve is located in the common intake passage. Downstream throttle velves located in the separate branched intake passages near the intake ports. A controller controls intake air actually introduced into the cylinder by actuating the downstream throttle valves to throttle down, smaller than the upstream throttle valve in a light engine load range and by actuating the upstream throttle valve to throttle down smaller than the downstream throttle valves in a heavier engine load range.

摘要： In a control system for an in-cylinder direct injection engine, an actual port intake air density ganmap is calculated based on the intake air temperature thae and the atmospheric pressure atp, a reference port intake air density ganmap* corresponding to the current operating conditions of the engine is read out of a map and compared with the actual port intake air density ganmap, and a target fuel pressure or fuel injection timing is compensatorily modified based on the comparison result. This prevents fuel spray and the tumble from being thrown out of balance due to a change in intake air temperature or atmospheric pressure thereby providing suitable mixture stratification.

摘要： In a control system for an in-cylinder direct injection engine, during idling operation, the fuel injection timing is compensated to the advance side for each cylinder so that the rate of change in crank angular velocity becomes smaller than a preset criterion while the fuel injection pressure of an injector is gradually reduced from a reference target fuel pressure to a preset lower limit. If the rate of change in crank angular speed becomes smaller than the criterion as a result of the above compensation, the fuel injection timing is compensated to the retard side so that the rate of change in crank angular velocity becomes smaller while the fuel pressure is gradually increased to the preset upper limit. Consequently, the unbalance of fuel spray and tumble due to deviations of fuel spray penetration and the like can be eliminated thereby providing suitable mixture stratification.

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.
