Abstract
Fuel-air mixture is supplied with stability to the neighboring area of an ignition plug without any effect on deflection of fuel spray due to the air flow (swirl/tumble) in a combustion chamber, and the deposition of fuel onto the side wall of a combustion chamber is reduced, leading to the prevention of occurrence of smoke. A fuel injection apparatus includes a fuel injection valve having a nozzle opening to a combustion chamber and an ignition plug. The fuel injection valve forms a fuel spray having different levels of average speed. The fuel spray has relatively high speed at least in half of a single cycle of a fuel injection, and after that, the fuel injection valve forms relatively low-speed fuel spray, and consequently, a fuel-air mixture including high-speed fuel spray is supplied to a neighboring area of the ignition plug.
