摘要： A cylinder injection valve that injects fuel inside a cylinder and an intake passage injection valve that injects fuel inside an intake passage are provided. When it is determined that deposit greater than or equal to a predetermined amount accumulates, the fuel is forcibly injected by the cylinder injection valve (deposit removing control). The deposit removing control is performed when a pressure of the fuel supplied to the cylinder injection valve is greater than or equal to a predetermined value and an engine load is relatively high. On the other hand, the deposit removing control is not performed when the pressure of the fuel supplied to the cylinder injection valve is greater than or equal to the predetermined value and the engine load is low.

摘要： In a dual-fuel injection operation, when a fuel injection time by a direct injector as determined on the basis of a direct fuel pressure is less than a minimum value, a dual-injection is performed with a duel injection rate such that the amount of fuel injected by the direct injector is greater than when the dual-injection is performed with a duel injection rate which is determined in accordance with an engine operation state. Thus, the amount of fuel injected by the direct injector is increased, so that the high-temperature fuel that has remained in a high-pressure fuel pipe connected to the injector is rapidly injected and consumed. As a result, the direct fuel pressure can be rapidly lowered, whereby the fuel injection time by the direct injector for implementing an amount of fuel injection in accordance with a direct injection command value can be rapidly increased to the minimum value.

摘要： A motor current is estimated based on a target motor speed, an actual motor speed, and an engine speed. When the estimated motor current exceeds a predetermined value equivalent to a heat limiting current value, a variation (motor speed F/B amount) of the target motor speed outputted to an EDU from an ECU is restricted so that the motor current was restricted and heat generation in motor is restricted. In consideration of a deterioration of responsivity of the variable valve timing control due to restriction of the motor current during execution of motor current restriction processing, an existence of the abnormalities of variable valve timing controller is determined based on a deviation of the target camshaft phase and the actual camshaft phase.

摘要： An ECU outputs a signal indicative of a target motor speed calculated based on a deviation between a target camshaft phase and an actual camshaft phase to an EDU. The EDU performs a feedback control of the output current (motor current) of the EDU so that the deviation is decreased, whereby an actual camshaft phase is feedbacked to a target camshaft phase. When the supply voltage of EDU is less than the operation limit voltage established higher than minimum operation assurance voltage, the variation of the target motor speed is restricted. Thereby, the output current of EDU is restricted, and further, when the supply voltage is less than minimum operation assurance voltage, the output current of EDU is intercepted.

摘要： An electronic control apparatus adjusts the pressure such that the fuel supply pressure of a high-pressure fuel supply system is reduced when in a low load mode corresponding to a low required injection quantity. When the operating status of the engine is shifted from a low load to a high load, the fuel supply pressure is boosted again. When determination is made that the current fuel supply pressure is lower than the target fuel supply pressure by at least a predetermined pressure C, the injection quantity ratio of the in-cylinder injector is set lower to reduce the required injection quantity of the in-cylinder injector. Accordingly, noise generated from the high-pressure fuel supply system can be minimized. Further, detrimental effects caused by insufficient fuel supply pressure of the high-pressure fuel supply system can be suppressed when the engine operating status is shifted from a low load to a high load.

摘要： A fuel vapor treating mechanism includes a canister for adsorbing fuel vapor produced in a fuel feed system. The treating mechanism purges the fuel vapor adsorbed by the canister, along with air, to an intake system of the engine. An ECU computes a value representing the flow rate of the purged gas as a value that represents the capability of the treating apparatus. The ECU sets a decision value in accordance with the amount of the fuel vapor produced in the fuel feed system. The decision value represents a required capability of the treating mechanism. When the value representing the capability is less than the decision value, the ECU prohibits stratified charge combustion and causes the engine to perform homogeneous charge combustion. Therefore, as many opportunities as possible are provided to perform stratified charge combustion, which improves fuel efficiency.
