Abstract

PURPOSE: To accelerate atomization and improve its efficiency especially under low load in a device which injects fuel intermittently corresponding to the amount of suction air and the number of revolution by forming a chamber to mix fuel with air at the tip of the injection valve.
CONSTITUTION: On the downstream side of a throttle valve 4 in an air admission cylinder 5, a fuel injection valve 1 is opened. At the end of the valve, a mixing chamber 13 is formed, and at its tip, a diffusing nozzle 14 projecting into the admission cylinder 5 is arranged. In this nozzle 14, a center hole 17 opening on the same axis as that of the injection valve 1 and an air introduction hole 15 in the same direction as that of the admission cylinder 5 are provided, and fuel discharged from a discharge port 11 on the lower side of the nozzle 14 is atomized. The mixing chamber 13 is provided with a bypass passage 10 which opens on the upstream side of the throttle valve 4, and especially when the throttle valve 4 is closed under low load, air is sucked through this passage 10 and atomizes fuel.
