    摘要: In an in-cylinder injection type spark ignition internal combustion engine in which the intake air amount is controlled by use of an intake valve or an exhaust valve, which is provided with mainly a variable valve mechanism, instable combustion during a low-load operation is avoided without an increase in pumping loss (without a decrease in the thermal efficiency). In the in-cylinder injection type spark ignition internal combustion engine, during low-load operation, on the basis of the cooling water temperature of the engine the opening and closing timing of the intake valve is controlled in a retard angle manner and the opening and closing timing of the exhaust valve is controlled in an advance angle manner. Furthermore, the fuel injection timing is controlled in a retard angle manner on the basis of the retard angle amount of the intake valve opening and closing timing.

    摘要: An engine that re-circulates its exhaust gas suffers decreased accuracy in estimating an EGR rate real-time especially while the operating state of the engine is in a transitional state, which often results in torque fluctuations and deteriorated exhaust gas.A sensor for directly detecting an EGR flow rate is disposed in an EGR path. An EGR rate and in-cylinder oxygen concentration are calculated from the output value of that sensor. In addition, when this EGR rate calculation method is used, the calculation is properly switched between a steady operation state characterized by a low load and small rotational fluctuations and a transitional operating state including the acceleration and deceleration. This makes it possible to correctly estimate the EGR rate and the in-cylinder oxygen concentration under a wide range of engine operation conditions, and thereby to avoid the fluctuation of torque and the deterioration of exhaust gas.

    摘要: Fuel injection technology of an internal combustion engine is configured in such a manner that in a case where in inlet pipe interior of the engine is partitioned by a rectifying plate into upper and lower flow paths, a flow velocity at a center of the flow path on an upper side, and at a center of the flow path on a lower side is increased. Consequently, a flow velocity distribution of air in a cylinder diametrical direction of a valve head of an inlet valve becomes a peak value on both sides of the valve head center. Therefore, by impinging most of the injected fuel spray upon both sides of the center of the valve head, vaporization of the fuel spray can be performed with good efficiency.

    摘要: Disclosed herein is a control apparatus for a spark-ignition engine that is capable of avoiding knocking at the time of high-load operation. With this control apparatus, a residual-gas suction unit or the like is not used, an exhaust gas does not deteriorate due to injection in a compression stroke, and a thermal efficiency also does not decrease. An engine control apparatus (ECU) 20 is used for the control of a direct-injection type spark-ignition engine. During the high-load operation of the spark-ignition engine, the ECU 20 injects fuel a plurality of times. In addition, the ECU performs first fuel injection toward internal EGR that exists in a combustion chamber of the spark-ignition engine.

    摘要: An object of the present invention is to provide a fuel injection control technique which maximizes engine power according to fuel evaporation characteristics. The fuel injection timing in the intake stroke is delayed according as a physical quantity affecting the fuel evaporation time changes such that the fuel evaporation time decreases. Further, the fuel injection timing when a physical quantity affecting the fuel evaporation time is such that the fuel evaporation time decreases is set closer to the end of the intake stroke than the fuel injection timing when the physical quantity is such that the fuel evaporation time increases. The fuel injection timing is controlled so as to maximize engine power according to fuel evaporation times.
