摘要： A control for an internal combustion engine having a fuel injection valve for directly injecting fuel to a combustion chamber of the engine, an ignition device for burning an air-fuel mixture containing the fuel injected from the fuel injection valve, and a variable cylinder management mechanism that is capable of changing the number of operating cylinders is provided. The control includes making a transition to an operating mode where the number of operating cylinders is decreased through the variable cylinder management mechanism. It is predicted based on an operating condition of the engine that an air-fuel ratio of an exhaust atmosphere of the engine becomes lean due to a stop of the fuel injection into one or more cylinders to be halted by the transition. If it is predicted that the air-fuel ratio of the exhaust atmosphere of the engine becomes lean, additional fuel is injected from the fuel injection valve to the one or more cylinders to be halted after ignition performed by the ignition device in a combustion cycle where the prediction is made.

摘要： An ignition timing control apparatus for an internal combustion engine having a plurality of cylinders, wherein operation of the engine is switchable between a partial-cylinder operation, which operates some of the cylinders, and an all-cylinder operation, which operates all of the cylinders. Basic ignition timing is calculated according to an operating condition of the engine. Knocking is determined based on an output of the knock sensor. A correction amount of the ignition timing is calculated according to a result of the knocking determination to suppress knocking, and the basic ignition timing is corrected with the calculated correction amount. Learning values of the correction amount are calculated corresponding, respectively, to partial-cylinder operation and all-cylinder operation, and one of the calculated learning values is used according to the operating condition of the engine.

摘要： In an intake system comprising a first intake passage (1) having an upstream end communicating with an intake duct (3) and a downstream end communicating with an intake port of an engine cylinder, a first intake control valve (6) provided in the first intake passage, a second intake passage (2) having an upstream end communicating with the intake duct and a downstream end communicating with the intake port of the engine cylinder, a second intake control valve (7) provided in the second intake passage, an accelerator pedal(ACL) and a control unit (100) for controlling opening angles of the first and second intake control valves, the second intake control valve is opened when the first intake control valve has opened to an effective opening angle and an intake air flow rate is required to be further increased. The effective opening angle may be defined in a region where a change in the intake air flow rate of the first intake passage for a given change in the opening angle of the first intake control valve falls below a prescribed level. Thereby, as the accelerator pedal is depressed, a continuous increase in the intake air flow rate without involving a saturated region can be achieved.

摘要： There is provided an ignition timing control system for a variable-cylinder internal combustion engine, which is capable of optimally reducing torque before the start of fuel cut-off operation, irrespective of whether the engine is in an all-cylinder operation mode or a partial-cylinder operation mode, thereby reducing shock caused by the fuel cut-off operation. When the internal combustion engine is operated under deceleration operating conditions, the start of cut-off of fuel supply is delayed for a predetermined time period, and ignition timing is corrected when the cut-off of fuel supply is being delayed for the predetermined time period. The amount of correction of the ignition timing is set to a different value depending on the operation mode.
