摘要： An engine 1 is stopped according to conditions when a vehicle has stopped, and the engine 1 is started by starting a motor/generator 2 when a request to restart the engine 1 which has stopped, is determined. Engine torque is absorbed by the motor/generator 2 so that that the starting torque according to an accelerator pedal depression after restart, is effectively the same torque for starting from the engine stop state as for starting from the engine idle state. In this way, the same starting performance is obtained when the vehicle starts from the engine stop state as when the vehicle starts from the engine idle rotation state.

摘要： In an internal combustion engine equipped with a pair of intake ports for each cylinder and capable of controlling a quantity of air entering the engine by controlling an intake valve open timing and an intake valve closure timing of each of a pair of intake valves located in the respective intake ports, a two-intake-valve operating mode is used in a high-load, high-speed operating range, whereas a one-intake-valve operating mode is used in predetermined low- and mid-load, low- and mid-speed operating ranges to create a great gas flow within the cylinder. A fuel injector is located in a first one of the intake ports to allow air flow through the first intake port over all operating ranges. An electronic engine control unit switches a compensating mode for an injection amount of fuel injected by the injector, based on changes in a quantity of wall fuel mass flow adhered onto the inner wall surface of the intake port during transient operating conditions, from one of a first compensating mode which is preprogrammed to be suitable for the one-intake-valve operating mode and a second compensating mode which is preprogrammed to be suitable for the two-intake-valve operating mode to the other.

摘要： A control system for a variable displacement internal combustion engine determines effective flow cross sectional area as a predetermined function of a cross sectional area given against a throttle position. The effective flow cross sectional area is used to determine a volumetric airflow ratio. A control unit is connected with cylinder operator means for deactivating and reactivating at least some of engine cylinders and varying strokes in a cycle. The control unit modifies the predetermined function in response to the number of cylinders being activated and the number of strokes in a current cycle.

摘要： When a failure of a variable valve timing mechanism of an internal combustion engine is detected, both a cylinder which is associated with the mechanism in failure and another cylinder which has a symmetrical phase in operation to the above-mentioned cylinder with respect to the stroke cycle are brought into inoperative condition. At the same time, the amount of air/fuel mixture fed to the remaining cylinders is increased. With this measure, engine vibration and power drop are suppressed or at least minimized.

摘要： A fuel injection control system for a cylinder direct injection spark-ignition internal combustion engine judges a homogeneous charge combustion condition which requires homogeneous charge combustion and a stratified charge combustion condition which requires stratified charge combustion, in accordance with an engine operating condition. Fuel is supplied on an intake stroke so as to form a rich equivalent ratio in the homogeneous charge combustion, and fuel is supplied on a compression stroke so as to form a lean equivalent ratio in the stratified charge combustion, with the rich equivalent ratio being richer in fuel than the lean equivalent ratio. The system then gradually changes over an equivalent ratio within a range between the rich and lean equivalent ratios when engine operation is changed over between the homogeneous charge combustion condition and the stratified charge combustion condition. The system then injects first and second quantities of fuel into a cylinder of the engine respectively on intake and compression strokes in each cycle of the cylinder at least at a predetermined time during a time period in which the equivalent ratio is gradually changed over.

摘要： An air-fuel controller for a water-cooled engine provided with a mechanism for detecting a mixing ratio error which is a difference between a target mixing ratio and a real mixing ratio of fuel and air provided for the engine, a mechanism for performing learning related to a fuel injection amount based on the detected mixing ratio error, a memory for storing this learned value, a mechanism for computing a fuel injection correction amount based on this learned value, and a mechanism for outputting a fuel injection amount corrected by this correction amount to the fuel injector. This engine may be provided for example with a mechanism to set the difference between the mixing ratio error in the transient state and after the transient state has terminated as a transient mixing ratio error, and a mechanism to update the learned value stored in the memory such that the transient mixing ratio error is minimized. In this manner, learning precision in air-fuel ratio control is improved.

摘要： A system for measuring a flow rate of intake air introduced into an internal combustion engine for an automotive vehicle, includes a hot-wire type air flow meter which comprises a sensor portion having a ceramic bobbin and a heating member wound onto the ceramic bobbin, and a control circuit for controlling current passing through the heating element so as to a hold temperature of the heating element constant. The hot-wire type air flow meter monitors the flow rate of the intake air to produce a sensor signal representative of the flow rate. The system also includes a control unit which receives the sensor signal to compensate a response time lag of the sensor signal, particularly when the engine operates in a transient state, such as acceleration and deceleration. The control unit derives a variation of the sensor signal value per a predetermined period of time to integrate the variation over a predetermined period of time to attenuate the integrated value, and corrects the sensor signal value on the basis of the attenuated value to use the result as a corrected value for air flow rate.

摘要： A system and method for controlling quantity of fuel injected to an internal combustion engine are disclosed in which a characteristic having a correlation to part of fuel supply quantity from an injector which has been supplied toward a wall surface of an intake air passage of the engine has been adhered onto the wall surface and will be brought away from the wall surface into a combustion chamber during a suction stroke at the present fuel injection timing is derived so that a correction quantity for a quantity of injected fuel is calculated on the basis of the derived characteristic. Therefore, an air-fuel mixture ratio when the engine falls in a transient state is not deviated from a target air-fuel mixture ratio so that an exhaust gas emission characteristic can be improved.
