関の燃料噴射装置。 A nozzle opening is formed at the tip of the compressed air passage facing into the combustion chamber, and an on-off valve for opening and closing the nozzle opening is arranged at the nozzle opening, and a compressed air supply for supplying compressed air into the compressed air passage. A fuel injection device is provided, and the fuel supplied into the compressed air passage is injected from the nozzle port into the combustion chamber by compressed air supplied into the compressed air passage from the compressed air supply device. In the internal combustion apparatus, the nozzle port is opened to inject fuel from the nozzle port, and then the nozzle port is opened until the pressure in the combustion chamber becomes higher than the compressed air pressure in the compressed air passage. Engine fuel injection system.
