摘要： An ECU feedback controls a discharge amount of a high-pressure pump in such a manner that a detected fuel pressure is consistent with a target fuel pressure. The ECU determines whether engine shut sown is imminent. When the ECU determines that engine shut down is imminent, the target fuel pressure is established lower than a normal fuel pressure. Since the engine is shut down in a condition where the fuel pressure is decreased, a fuel leakage from a fuel injector is unlikely.

摘要： If a high-pressure pump discharges fuel in an injection waiting period from injection setting to injection start, fuel pressure to occur at injection start time is estimated and a fuel pressure correction coefficient is calculated based on the estimated fuel pressure. If there is no fuel discharge in the injection waiting period, the fuel pressure sensed at the injection setting is regarded as the fuel pressure of the injection start time, and the fuel pressure correction coefficient is calculated based on the sensed fuel pressure. A final injection period is calculated by correcting a basic injection period with the fuel pressure correction coefficient. Thus, fuel pressure correction of the injection period is performed accurately even if actual fuel pressure fluctuates due to the fuel discharge from the high-pressure pump during the injection waiting period.
摘要翻译： 如果高压泵在从注射设定到注射开始的注射等待期间排出燃料，则估计在注射开始时间发生的燃料压力，并且基于估计的燃料压力计算燃料压力校正系数。 如果在喷射等待期间没有燃料排出，则将在喷射设定下检测到的燃料压力视为喷射开始时间的燃料压力，并且基于检测到的燃料压力计算燃料压力校正系数。 通过用燃料压力校正系数校正基本喷射周期来计算最终喷射周期。 因此，即使实际的燃料压力由于在喷射等待期间从高压泵的燃料排出而波动，也能够准确地进行喷射期间的燃料压力校正。

摘要： A startup controller calculates a fuel pressure difference across a discharge stroke of a high-pressure pump at an end of an initial discharge after cranking is started. At the injection setting, the startup controller estimates a fuel pressure increment from an injection setting to an injection start based on the fuel pressure difference. The startup controller adds the fuel pressure increment to a fuel pressure sensed at the injection setting to estimate a fuel pressure at the injection start. The startup controller determines whether to perform or to prohibit the injection based on whether the estimated fuel pressure at the injection start is equal to or higher than an injection permission fuel pressure.

摘要： A system for solving disturbances in the air-fuel ratio caused by a change in the normal correction factor, and permitting achievement of a highly accurate air-fuel ratio control. Fuel evaporative gas generated in a fuel tank is adsorbed in a canister, and then discharged into an intake pipe of an internal combustion engine. ECU calculates the fuel supply quantity to the internal combustion engine on the basis of the condition in which the internal combustion engine is operating, performs feedback control and learning control of an air-fuel ratio on the basis of a detection signal from an oxygen sensor, and corrects the fuel supply quantity by means of an air-fuel correction factor. ECU also controls fuel injection by an injector by decrement-correcting the fuel supply quantity in response to the quantity of discharged evaporative gas. Furthermore, ECU adjusts, upon decrement correction of the fuel supply quantity in response to the quantity of discharged evaporative gas, the quantity of the decrement correction so as to be proportional to the normal correction factor including the air-fuel ratio correction factor.

摘要： A fuel injection control device for an engine executes a split injection constructed by a fixed injection and a variable injection. A required injection amount of the fixed injection is set in a low range. A required injection amount of the variable injection is set in a high range. An injection amount in the high range is larger than that of the low range. The required injection amount of the variable injection is changed within the high range while the required injection amount of the fixed injection is fixed when a load of the engine is varied while the split injection is performed. An injection control characteristic is corrected based on an actual air-fuel ratio detected before the load is varied and an actual air-fuel ratio detected after the load is varied.

摘要： A fuel injection controller of an in-cylinder injection engine determines that a combustion state has deteriorated and executes a split injection for injecting fuel in split amounts into each cylinder in multiple injection events in a cycle of the cylinder if it is determined that a combustion fluctuation is greater than a predetermined determination value during operation of the engine. The fuel injection controller increases a ratio of an injection amount of the first injection event in the split injection and lengthens an injection interval between the injection events as the combustion fluctuation increases. Thus, a wet amount of the injected fuel is reduced to expedite atomization of the injected fuel and to homogenize an in-cylinder mixture gas. As a result, the combustion state is improved.

摘要： A control mode of an intake valve lift controller is changed between a low-speed mode and a high-speed mode. Based on the control mode, an ignition timing is adjusted. When a knocking is detected by a knock sensor after the control mode is changed from the low-speed mode to the high-speed mode, it is determined that the intake valve lift controller has a malfunction in which the intake valve lift controller is stuck in the low-speed mode. When a combustion stability is lowered to a predetermined level after the control mode is changed from the high-speed mode to the low-speed mode, it is determined that the intake valve lift controller has a malfunction in which the intake valve lift controller is stuck in the high-speed mode.
