摘要： An internal combustion engine includes an in-cylinder injector for injecting fuel into a combustion chamber of the engine and an intake system injector for injecting fuel into an intake system connected to the combustion chamber. In a starting state of the engine, an electronic control unit (ECU) causes the in-cylinder injector to perform only the initial injection to the combustion chamber, and causes the intake system injector to perform fuel injections after the initial injection. As a result, favorable engine startability is ensured, and the emission of unburned components is suppressed in the engine starting state.

摘要： An air flow control device of an engine comprising an air flow control valve arranged in the intake passage and actuated by the vacuum operated diaphragm type drive apparatus. At the cranking of the engine, the air flow control valve is held in the closed state. When the engine speed exceeds a predetermined engine speed, for example, 400 rpm, a valve open signal for the air flow control valve is given to the vacuum operated diaphragm type drive device. After the valve open signal is given, during the valve opening delay period of the air flow control valve, an opening area of the idling speed control valve is increased.

摘要： An engine includes: a valve stop mechanism that varies the number of operating cylinders as a cylinder cut-off mechanism; and a blow-by gas recirculation system that has a blow-by gas passage that returns blow-by gas, flowing from a combustion chamber to a crankcase, to an intake passage and a PCV valve that is equipped with an electric motor and that adjusts the flow rate of gas returned to the blow-by gas passage. A control device variably sets the opening degree, corresponding to a target value of the flow rate of gas, of the PCV valve on the basis of an intake pressure in an intake passage to adjust the opening degree of the PCV valve so that the flow rate of gas becomes the target value.

摘要： An engine, having an intake passage, a throttle valve arranged in the intake passage, and a fuel injector arranged in the intake passage for injecting fuel into the intake passage, comprises an air-flow control valve arranged in the intake passage between the fuel injector and the throttle valve. The air-flow control valve is controlled to close during the engine starting operation, and to open after the engine starting operation completes. The air-flow control valve has a valve element having an axis about which the element is rotatable when the valve is opened or closed. The rotational direction of the valve element is selected so that air flowing through the valve is guided by the valve toward the fuel injector when the air-flow control valve is controlled to an intermediate open position which is between the closed position and the full open position.

摘要： A control apparatus calculates a exhaust gas air-fuel ratio of a plurality of cylinders, in which the operation angle of an intake valve is set to a predetermined operation angle, e.g., a maximum operation angle, based on a value output from an air-fuel ratio sensor so as to minimize a variation in an fuel injection quantity between the plurality of cylinders by that exhaust gas air-fuel ratio. That is, the exhaust gas air-fuel ratio of the plurality of cylinders, in which the valve opening characteristics of the intake valve and an exhaust valve are set such that the intake air amount to be introduced into the plurality of cylinders is limited by the opening amount of a throttle valve, for example, and not limited by the valve opening characteristics of the intake valve or the exhaust valve is calculated, and the variation in the fuel injection quantity among the plurality of cylinders is then reduced by that exhaust gas air-fuel ratio. Then, the variation in valve opening characteristics among the cylinders is reduced.
