    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 (2) 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 (2) and an exhaust valve (3) 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 (56), for example, and not limited by the valve opening characteristics of the intake valve (2) or the exhaust valve (3) 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.

    摘要： An engine ECU executes a program including the step (S100) of detecting an engine coolant temperature (THW), the step (S120) of selecting a map for a warm state as the map for calculating a fuel injection ratio (or a DI ratio) (r) when the engine coolant temperature (THW) is equal to or higher than a temperature threshold value (THW(TH)) (YES in S110), the step (S130) of selecting a map for a cold state as the map for calculating the fuel injection ratio (or the DI ratio) (r) when the engine coolant temperature (THW) is lower than the temperature threshold value (THW(TH)) (NO in S110), and the step (S140) of calculating the fuel injection ratio between the in-cylinder injector and the intake manifold injector (or the DI ratio) (r) based on the engine speed, load factor, and the selected map.

    摘要： An injection controller for an internal combustion engine that suppresses the accumulation of deposits on a nozzle hole of a direct injection valve. The injection controller (50) includes the direct injection valve (21), which injects fuel into a cylinder, and an intake passage injection valve (22), which injects fuel into an intake passage. An ECU (31), which is connected to the direct injection and intake passage injection valves, executes a first fuel injection mode for injecting fuel with the direct injection valve and a second fuel injection mode for injecting fuel with the intake passage injection valve. The ECU switches fuel injection modes from the second fuel injection mode to the first fuel injection mode for a predetermined period when fuel is to be injected in the second fuel injection mode.
