Internal combustion engine with fuel injection unit.

摘要

The present invention relates to a fuel injection unit (1) for an internal combustion engine comprising a fuel passage (14) for supplying fuel and an air passage (16) for supplying pressurized air, into which the outlet (15) of said fuel passage (14) for supplying fuel opens and an injection valve (10) for opening and closing at least the air outlet (16a) of said air passage (16), wherein said fuel passage (14) and said air passage (16) are provided independently of each other. Moreover, fuel injection is performed either with a certain delay with respect to the initiation of the pressurized air injection or is carried out simultaneously therewith in order to ensure that the fuel becomes sufficiently atomized and that improved combustion stability is obtained.
