Abstract: A fuel pressure control device has a feedback control section for setting a feedback control amount (F/B control amount) in accordance with a deviation between target fuel pressure and actual fuel pressure and a feedforward control section for setting a feedforward control amount (F/F control amount) in accordance with a required fuel injection amount and engine rotation speed. When an engine operation state is an off-idling condition, F/F-F/B combination control for validating the F/F control amount and for setting a control amount of a high-pressure pump by adding the F/F control amount to the F/B control amount is performed. When the engine operation state changes from the off-idling condition to an idling condition, control is switched to F/B single control for invalidating the F/F control amount and for using only the F/B control amount.

Abstract: A direct injection engine is provided with valve timing controllers in an intake side and an exhaust side. While the engine is running in a homogeneous combustion mode, a computer determines whether a valve overlap period exists, in which both the intake valve and the exhaust valve are opened. When the valve overlap period exists, the fuel injection timing is established within a valve overlap period to increase a temperature in a cylinder, so that an atomization of the injected fuel is expedited. When no valve overlap exists, the fuel injection timing is established at the vicinity of the valve opening timing of the intake valve, whereby the atomization of the injected fuel is expedited.

Abstract: 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.

Abstract translation: 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。

Abstract: 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.

Abstract: An air-fuel ratio control apparatus of an internal combustion engine capable of learning and controlling an air-fuel ratio accurately both in idling and non-idling without being affected by concentration of evaporated fuel. Uniform deviation of an air-fuel ratio is detected before starting purging of the evaporated fuel (steps S133 to S137), air-fuel ratio learning values KGI.sub.0 to KGI.sub.7 and KGS.sub.0 to KGS.sub.7 are stored respectively so that the uniform deviation shows a predetermined value or lower both at idling time and at non-idling time (steps S138 to S142), and air-fuel learning values KG.sub.0 to KG.sub.7 in respective areas including idling are updated or renewed with a value obtained by leveling or averaging air-fuel ratio learning values KGI.sub.0 to KGI.sub.7 and KGS.sub.0 to KGS.sub.7 stored both at idling time and at non-idling time (step S145). Thereafter, purging of the evaporated fuel is started, and area learning of the air-fuel ratio is also executed by air-fuel ratio learning values KG.sub.0 to KG.sub.7 in respective areas.

Abstract: 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.

Abstract: 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.
