Abstract: A fuel injection device injects natural gas from a first injection hole of a first housing and injects light oil form a second injection hole of a second housing. A weld part as a fixation part fixes positions of the first injection hole and the second injection hole such that a spray of natural gas injected from the first injection hole and a spray of light oil injected from the second injection hole contact each other. Thus the spray of light oil self-ignites by compression of air in a cylinder of an internal combustion engine and the spray of natural gas burns by ignition from a flame of the self-ignited light oil.

Abstract: An internal combustion engine control apparatus includes a fuel injection apparatus injecting fuel into a combustion chamber a plurality of times during a single cycle, and controls an internal combustion engine that performs compression combustion. The internal combustion engine control apparatus includes an injection command unit and an injection specification determining unit. The injection command unit commands the fuel injection apparatus to perform: a main injection for a main combustion that generates torque; and a preceding injection that is performed at a stage before the main injection. The injection specification determining unit determines a penetration force of a spray produced by the preceding injection or an injection direction of the preceding injection, such that a range of reach of the spray produced by the preceding injection is closer to a nozzle hole of the fuel injection apparatus than a range of reach of a spray produced by the main injection.

Abstract: A fuel injection device is used in an internal combustion engine having a combustion chamber partitioned by a cylinder head, a cylinder, and a piston crown surface so that at least one of the amount of NOx, Pmax, and a thermal efficiency η is maintained at a predetermined value. The fuel injection device includes a fuel injection change unit. The fuel injection change unit virtually divides the combustion chamber into N number of combustion zones where N is a natural number of 2 or more, and can change a fuel injection method according to the respective combustion zones. The fuel injection change unit divides the combustion chamber into the N number of combustion zones, thereby being capable of eliminating a difference of heat in the respective combustion zones, and precisely controlling an in-cylinder pressure P in the combustion chamber. As a result, the amount of NOx and the thermal efficiency can be optimized. Therefore, both of a reduction in the amount of NOx and the high thermal efficiency can be achieved.
