摘要： Each cylinder is provided with an ignition plug, two intake valves, an intra-cylinder fuel injector, and a port fuel injector. When homogeneous combustion is demanded, the intra-cylinder fuel injector and port fuel injector inject fuel on the same engine cycle. The port fuel injector is installed so that the amount of fuel directed toward outer regions of the intake valves is larger than that of fuel directed toward inner regions of the intake valves, thereby causing only fresh air to flow to regions near the inner regions of the intake valves.

摘要： In an internal combustion engine, it is first determined whether a load factor of the internal combustion engine is a specified value or more and the engine speed of the internal combustion engine is a specified speed or less. If these conditions are satisfied, fuel is injected from both of a port injection valve and a direct injection valve, and a fuel injection timing of the direct injection valve is decided so as to inject fuel from the direct injection valve during the compression stroke of the internal combustion engine.

摘要： A control system controls a spark-ignition internal combustion engine. The spark-ignition internal combustion engine includes a cylinder, and a fuel injection valve arranged in the cylinder; and an intake port that communicates with the cylinder, and a fuel injection valve arranged in the intake port. Fuel is injected from both the fuel injection valves in at least a part of an operating range. If combustion fluctuations exceed a predetermined amount, in consideration of a preset proportion of fuels to be injected into the cylinder and the intake port, a proportion of fuel to be injected into the cylinder is decreased and a proportion of fuel to be injected into the intake port is increased.

摘要： A direct fuel injection-type spark-ignition internal combustion engine is disclosed. The engine comprises a fuel injector for injecting fuel as a spray in nearly the shape of a fan having a relative small thickness, a spark plug and a cavity formed on the top surface of a piston. The cavity has a long and narrow groove-like shape. The spray is injected by the fuel injector such that the spray is almost parallel with the center axis of the piston, and impinges in the cavity. The spark plug is arranged in the upper portion of the cylinder to face the cavity.

摘要： An electrically driven type low-pressure fuel pump whose flow rate can be set draws fuel from a fuel tank and discharges it at a prescribed pressure commonly to a low-pressure fuel supply system including intake manifold injectors and a low-pressure delivery pipe and to a high-pressure fuel supply system including in-cylinder injectors, a high-pressure delivery pipe and a high-pressure fuel pump. The discharge flow rate of the low-pressure fuel pump is set based on required supply quantities to the low-pressure fuel supply system and to the high-pressure fuel supply system obtained according to the engine operation conditions. The discharge quantity of the fuel pump in the internal combustion engine can be set as appropriate, and thus, deterioration in fuel efficiency due to excessive flow rate setting and operation failure due to insufficient fuel supply can be prevented, whereby reliability is improved.

摘要： A relationship between an inner diameter A of a sac volume and a distance from a central axis of the sac volume is set to satisfy a condition of 1≦A/2B≦20. In this way, fuel, which flows from the sac volume into each injection hole, will be injected from the injection hole without being spaced from a wall surface of a valve body, which form the injection hole. Thus, it is possible to limit adhesion of a foreign substance to a wall surface of each injection hole. Furthermore, even if the foreign substance is adhered to the wall surface of the injection hole, the foreign substance can be removed by the fuel, which flows through the injection hole.
摘要翻译： 囊体的内径A与囊体的中心轴的距离之间的关系被设定为满足1 <= A / 2B <= 20的条件。 以这种方式，从囊容积流入每个喷射孔的燃料将从喷射孔喷射而不与形成喷射孔的阀体的壁面间隔开。 因此，可以限制异物与每个喷射孔的壁面的粘附。 此外，即使异物附着在喷射孔的壁面上，也可以通过喷射孔流动的燃料除去异物。

摘要： A piezoelectric-element drive apparatus includes a direct-current power supply. An energy storing capacitor is connected in parallel with the direct-current power supply. An energy-transfer switching element becomes on when energy is transferred from the energy storing capacitor. A piezoelectric element connected in parallel with the energy storing capacitor receives energy and expands when the energy-transfer switching element becomes on. A discharging coil is connected in parallel with the piezoelectric element. A discharging switching element is operative for discharging the piezoelectric element via the discharging coil. A coupling transformer is provided between the energy storing capacitor and the piezoelectric element.
