ABSTRACT:
In known equipment for injecting a fuel/gas mixture, having a fuel injection valve protruding into a stepped longitudinal bore of a gas distributor part, the formation of as homogeneous as possible a fuel/gas mixture and the fine atomization of the fuel are not assured if the gas envelops the injected fuel approximately in the flow direction of the fuel. The novel apparatus has a swirl element in the longitudinal opening of the gas distributor part, the swirl element having a mixing opening extending concentrically with the longitudinal valve axis; at least one curved, groovelike flow conduit, formed in the wall of the swirl element, discharges into this mixing opening. As a result, particularly fine atomization of the fuel and the formation of the most homogeneous possible fuel/gas mixture are assured. The embodiment of the apparatus is especially suitable for use in mixture-compressing internal combustion engines with externally supplied ignition.
