摘要： A dual-injector fuel injection engine includes a cylinder block, a cylinder head, an intake port, an intake manifold, a surge tank, an in-cylinder injector, an intake pipe injector, and first and second delivery pipes. The in-cylinder injector is positioned below the intake port, when seen from an axial direction of a crank shaft, and attached to the cylinder head. The intake pipe injector and the second delivery pipe are supported above the intake port, when seen from the axial direction of the crank shaft, by the intake manifold to be close to the intake port.

摘要： Fuel pipes guide fuel from a fuel tank provided in a rear area of the vehicle to a low-pressure fuel supply system and a high-pressure fuel supply system, respectively, for injecting the fuel to an engine provided in a front area of the vehicle. A branch point between the fuel pipes is arranged in the vicinity of the fuel tank to secure a long pipe length between the low-pressure fuel supply system and the high-pressure fuel supply system. This can suppress variation in fuel pressure at the low-pressure fuel supply system attributable to the fuel that is discharged from the high-pressure fuel pump within the high-pressure fuel supply system back to the fuel pipe.

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。
