ABSTRACT:
A fuel injection apparatus for an internal combustion engine arranged so as to inject different types of fuel in a given order has fuel injection nozzles respectively corresponding to cylinders of the internal combustion engine, compressors for respectively delivering an auxiliary fuel to the fuel injection nozzles, and a main fuel injection pump for compressing and delivering a main fuel to the fuel injection nozzles at respective given timings. Each fuel injection nozzle has a fuel reservoir around the distal end portion of a nozzle needle in the vicinity of a fuel injection port. The auxiliary fuel from the corresponding compressor is delivered to a portion of the fuel reservoir which is adjacent to the fuel injection port. A second passage is formed to receive the auxiliary fuel from a portion of the fuel reservoir which is adjacent to the fuel injection port. A first passage is formed to communicate with a portion of the fuel reservoir which is spaced apart from the fuel injection port. The first passage receives the main fuel from the fuel reservoir.
