Internal combustion engine with air-fuel mixture injection

Abstract

A structure for supplying assist air to an air-fuel mixture injection valve including a device for limiting the intake air taken by a compressor, whereby a drive force of the compressor required for compressing air is reduced, and fuel efficiency is achieved. The structure includes an inlet port of the compressor and a venturi member of an air-intake pipe brought into communication via an inlet channel. The air in the air-intake pipe is regulated by the venturi member through the inlet channel by driving the compressor and is taken to the compressor. Air compressed in the compressor is supplied through a high-pressure air channel to the air introduction portion of the fuel injection valve device, where fuel injected from the fuel injection valve and high-pressure air supplied to the air introduction portion are mixed to air-fuel mixture, and the air-fuel mixture is injected by the air-fuel mixture injection valve.
