摘要： In an internal combustion engine, an amount of spray attaching onto an inner wall surface of an intake pipe is reduced by forming a two-directional spray of highly atomized fuel. The highly atomized two-directional spray can be obtained by a spray forming means constructed by piling a fuel in-plate forming fuel passages, a swirl plate forming fuel passages for adding swirl forces to the fuel, and an injection plate for determining injection directions of the fuel. Further, penetrations of the sprays injected toward two directions are made different from each other.

摘要： Atomizing air flowing in an atomizing gas passage is merged with a fuel spray to promote atomization of the fuel, and carrier air flowing in a carrier gas passage is merged with the fuel spray at a further downstream position so as to surround the fuel spray. By doing so, the atomized fuel spray is carried to the downstream side so as to prevent the fuel spray from adhering onto the wall surface. The starting-up performance, fuel consumption and exhaust gas cleaning of an internal combustion engine are improved in this way.

摘要： In a multi-port fuel injection system for a lean burn engine, the attaching of fuel particles from the fuel spray onto a wall surface, which is a problem in atomizing injected fuel, is reduced, and the quality and shape of the mixed gas in the cylinders of the engine is improved. The engine has a fuel injector 1; an intake valve 6 for opening and closing an intake port; and an intake air flow control device 10. The injected fuel is shaped to provide a low penetration fuel spray when the engine is operated in a low load state and at a low rotation speed, and the injected fuel is shaped to provide a high penetration fuel spray when the engine is operated in a high load state and at a high rotation speed. The fuel is injected in synchronism with the intake stroke of the engine, and it is transported by the air flow flowing through the intake air flow control device 10 to suppress the attaching of fuel particles from the fuel spray onto a wall surface of the intake manifold.

摘要： A main passage mounting a throttle valve and an air bypass flow passage for reducing HC emission by promoting atomization of the fuel spray injected from the assembly pipe fuel injector are integrated in a body of an intake air control device arranged upstream of an assembly pipe in a one-piece structure to form a unit. Thereby, the intake air control device can be easily manufactured and easily mounted on and dismounted from the intake air system. The amount of HC emitted during warming-up operation of an internal combustion engine is reduced by efficiently supplying fuel spray injected from an assembly pipe fuel injector at the time of starting and warming-up operations for the internal combustion engine.
