Abstract

A device and method for injecting a fuel-gas mixture. The novel device has an advantage of a simple and exact adjustment of an annular gas gap. The adjustment of the axial extension of a narrow annular gap is effected by varying the axial spacing between the face end of a retaining shoulder on a fuel injection valve and the face end of the bottom part in the region of the annular gas gap of the gas enveloping bushing. The proposed device for injecting a fuel-gas mixture is especially suitable for injection into the intake tube of a mixture-compressing internal combustion engine with externally supply ignition.
