摘要： The present invention relates to an automotive vehicle engine having controls for switching between a whole cylinder working mode and a partial cylinder non-working mode by making a valve motion arrangement operated in the intake and exhaust process. The automotive vehicle engine comprises-a revolution sensor, a boost pressure sensor, an ignition driving apparatus and a controlling apparatus for controlling the cylinder suspending mechanism and the ignition driving apparatus. The partial cylinder non-working mode or the all cylinder working mode is determined on the basis of the revolution speed "Ne" and the boost pressure data "Pb". An ignition timing retard process and an idle speed shifting-up process are performed so as to control the torque variation of the engine caused at the time when the all cylinder working mode is switched to the partial cylinder non-working mode or when the partial cylinder non-working mode is switched to the all cylinder working mode, thereby preventing torque shock from occurring and thereby preventing the engine from stopping and enhancing drivability.

摘要： An apparatus for controlling an ignition timing of a cylinder-injection gasoline engine 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 in consideration of a delay in increase of the wall temperature of a combustion chamber when the acceleration of a vehicle is detected by the change of the throttle opening. In order to prevent knocking of the engine attributable to the increase of the wall temperature, the ECU gradually decreases an advance angle for the ignition timing to 0 with the passage of control time. When the engine 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.

摘要： There is provided a combustion chamber structure in an internal combustion engine in which, at a peripheral portion of a combustion chamber, a gap between a cylinder head lower face and a piston upper face is small in intake-to-intake and exhaust-to-exhaust zones and gradually increases toward an intake-to-exhaust zone. According to such design, the mixture in the peripheral portion of the combustion chamber can smoothly flow from the intake-to-intake and exhaust-to-exhaust zones to the intake-to-exhaust zone along the peripheral face of the cylinder. The flow of air-fuel mixture from the intake-to-intake zone collides at the center of the intake-to-exhaust zone with the flow of mixture from the exhaust-to-exhaust zone, and the combined flow goes over a conical tapered portion in the upper face of the piston and vigorously enters a central recessed portion thereof. Therefore, it is possible to satisfactorily mix an air-fuel mixture with a simplified configuration.

摘要： An engine control unit of a control apparatus for an in-cylinder injection internal combustion engine sets a fuel injection timing for a compression-stroke injection mode in accordance with a fuel injection quantity, and corrects the fuel injection timing according to an engine cooling water temperature. When the cooling water temperature is lower than a temperature observed when a warm-up operation is completed, the fuel injection timing for the compression-stroke injection mode is corrected for advance or retard on the basis of the engine characteristic proper, and fuel is injected at an appropriate time such that the fuel evaporation rate and the fuel stratification degree which permit the stabilized combustion of the fuel injected into the combustion chamber are attained, whereby the fuel is evaporated satisfactorily. Thus, the occurrence of misfire and the emission of harmful gas components can be restrained effectively during the warm-up operation in the compression-stroke injection mode.

摘要： Disclosed is an automobile engine which has different ranges for the partial cylinder operation mode depending upon whether or not the engine is idling. The partial cylinder operation mode is selectable in different operation ranges in response to operating status of an air-conditioner, a power steering switch or a throttle opening sensor. Thus, the engine can reliably assume the partial cylinder operation mode in a wide operation range without stall, thereby accomplishing fuel saving.

摘要： In a fuel blending ratio detecting method, a first blending ratio of the methanol in the fuel supplied to an internal combustion engine is detected by a blending ratio sensor; an air/fuel ratio feedback compensation coefficient computed on the basis of an output of an O.sub.2 sensor is used to compute a feedback learned value, and the current blending ratio compensation coefficient is multiplied by this value to compute the next blending ratio compensation coefficient so as to obtain a second blending ratio; the current blending ratio compensation coefficient is multiplied by a peak mean value of the computed feedback compensation coefficient to compute the next blending ratio compensation coefficient so as to obtain a third blending ratio; and the first, second or third blending ratio is selected according to the operating conditions of the internal combustion engine. Thus, the selected blending ratio is always used as the control blending ratio very close to the true ratio, so that the internal combustion engine can be accurately controlled.
