Abstract

The device for the indirect injection of fuel into the intake tube upstream of the inlet valves comprises means for injecting at the intake time, into the combustion chamber, a metered amount of fuel directed to this end into a gaseous flow of air at substantially sonic speed, induced by a set of stepped tuyeres having a moderate divergent angle, at the level of the neck portion of said tuyeres. This device is applicable notably to the air-fuel feeding of engines for improving the fuel metering precision and the quality of the air-fuel mixture and therefore the degree of atmospheric pollution.
