ABSTRACT:
A fuel injection system is proposed which serves to supply fuel to a mixture-compressing, externally ignited internal combustion engine in accordance with operational parameters of the engine. The fuel injection system includes a metallic fuel distributor tube, which communicates via at least one branch line with at least one fuel injection valve, wherein the branch line is embodied as a metal tube and is connected with the fuel injection valve by means of a threaded assembly. The material used for the branch line is easily bendable metal. Between the threaded assembly at the branch line and the fuel injection valve, a thin-walled metallic bellows is provided, by means of which a lateral displacement between the attachment point of the branch line at the fuel distributor tube and the installation point of the fuel injection valve is compensated for, and the noise of operation produced by the fuel injection valve is damped.
