Abstract
A device for injecting a fuel-gas mixture having a cup-shaped gas enveloping sleeve in which the cylindrical part of the gas enveloping sleeve permits exact centering of the gas enveloping sleeve relative to the fuel injection valve. The novel device while having very exact centering of the gas enveloping sleeve relative to the fuel injection valve has the advantage of a simple, economical manufacture. The device includes radially inwardly pointing guide strips that rest with their face ends on the circumference of the fuel injection valve and thus in a simple way center the gas enveloping sleeve relative to the fuel injection valve. The device for injecting a fuel-gas mixture is especially well-suited for injection of a fuel gas mixture into the intake tube of a mixture-compressing internal combustion engine with externally supplied ignition.
