摘要： An automobile engine (E) capable of changing over the operating area thereof between an operating area with all the cylinders being in action and one with a certain number of cylinders being at rest by stopping the operation of valve operation mechanisms for suction and exhaust in selected cylinders out of a plurality of cylinders, in particular, the engine comprising an engine revolution sensor (12), a boost pressure sensor (10), ignition driving devices (23, 24, 25), and a control device (15) for controlling a mechanism for stopping cylinders and the ignition driving devices, wherein an operating area with certain number of cylinders being at rest is determined from information on engine revolutions Ne and boost pressure Pb, and wherein a torque fluctuation of the engine occurring when the engine operating area is switched from an operating area with all the cylinders being in action to an operation area with a certain number of cylinders being at rest, and vice versa is offset by the retard amount processing of ignition timing or by idle-up so as to prevent the generation of torque shocks resulting from extraordinary change in output occurring when such switching is carried out to thereby prevent stall or improve drivability.

Date Nov. 21, 1996A fuel injection control apparatus for a cylinder-injection type internal combustion engine performs a switching of fuel injection control modes in accordance with the operating state of the internal combustion engine when the engine is operating in a steady state. When the internal combustion engine is operating in a transitional state, for example, when the engine is accelerating or decelerating, a fuel injection control mode suited for the transitional operating state is selected preferentially over the mode selection for a steady state by a fuel injection control mode switching means. Consequently, the fuel injection control apparatus permits desirable operation of the internal combustion engine, making it possible to greatly improve the drivability of a vehicle in which the engine is installed.

摘要： AN APPARATUS FOR CONTROLLING AN IGNITION OF A CYLINDER-INJECTION GASOLINE ENGINE (1) INCLUDES AN ELECTRONIC CONTROL UNIT (ECU) FOR CONTROLLING THE OPERATION OF AN IGNITION COIL. THE ECU ADVANCES THE IGNITION TIMING IN ACCORDANCE WITH THE THROTTLE OPENING (qTH) IN CONSIDERATION OF A DELAY IN INCREASE OF THE WALL TEMPERATURE (TCW) OF A COMBUSTION CHAMBER (5) WHEN THE ACCELERATION OF A VEHICLE IS DETECTED BY THE CHANGE OF THE THROTTLE OPENING (qTH). IN ORDER TO PREVENT KNOCKING OF THE ENGINE (1) ATTRIBUTABLE TO THE INCREASE OF THE WALL TEMPERATURE (TCW), THE ECU GRADUALLY DECREASES AN ADVANCE ANGLE FOR THE IGNITION TIMING TO 0 WITH THE PASSAGE OF CONTROL TIME. WHEN THE ENGINE (1) IS REACCELERATED DURING THE ADVANCE ANGLE CORRECTION, THE ECU NEWLY SETS AN ADVANCE ANGLE FOR THE IGNITION TIMING AND A CONTROL TIME, CORRESPONDING TO THE INCREASE OF THE WALL TEMPERATURE (TCW).

摘要： A control apparatus for a cylinder-injection engine includes an electronic control unit which calculates an average effective pressure according to throttle opening and engine rotation speed, calculates an intake air amount per intake stroke according to an intake air amount detected by an airflow sensor and engine rotation speed, and calculates a volumetric efficiency based on the calculated intake air amount. A fuel injection amount is calculated according to an intake air amount and a target air-fuel ratio calculated based on a target average effective pressure when a compression-stroke injection mode is selected, and according to the intake air amount and a target air-fuel ratio calculated based on the volumetric efficiency when an intake-stroke injection mode is selected, whereby a fuel injection control is made based on the target air-fuel ratio suited to the injection mode, while managing the target air-fuel ratio, thereby always ensuring a proper combustion control and a stabilized engine operating state. During the changeover of injection mode, the target air-fuel ratio, determined for an injection mode before the changeover, is changed, at a speed which changes stepwise, to that determined for an injection mode after the changeover, whereby an engine torque change caused by a sudden change in fuel injection amount is suppressed to a minimum, thereby reducing a torque shock.
