An injection valve arrangement for an internal combustion engine, especially a large so called gas diesel engine is disclosed. The arrangement comprises an engine cylinder head (1), first valve means (4,5) in the form of at least two needle valves (4,5) or the like for injecting gaseous fuel directly into a cylinder of the engine; and second valve means (3) in the form of a needle valve (3) or the like, for injecting so called pilot fuel into the cylinder in order to enrich the mixture therein for ignition. The gas needle valves (4,5) are arranged around the pilot needle valve (3) in a common valve housing (2) supported to the cylinder head (1) . Control of the operation of the gas needle valves (4,5) is arranged by means of a common control valve (12) preferably under electrical control. In addition, the valve needles (4a,5a) of the gas needle valves (4,5) are mechanically connected to each other so that the movements thereof occur concurrently. <IMAGE> |
