Abstract (en)
[origin: EP0922852A2] A fuel system is described which comprises an injector (12) mounted in a bore of an engine cylinder head (10), a high pressure pipe (30) arranged to supply fuel to the injector (12) from a common rail (32), an end region of the pipe (30) adjacent the injector (12) extending in a direction substantially perpendicular to an axis of the injector (12), and a clamp member (38) arranged to clamp the end region of pipe (30) to the injector (12), the clamp member (38) including a drilling (40) defining a return fuel passage extending between the injector (12) and a backleak channel (44) provided in the cylinder head (10) or a cam box wall or cover (22) of the engine. The injector (12) may be modified to define a flow passage (40) which communicates directly with the backleak channel (44), thus avoiding providing a drilling in the clamp member (38). <IMAGE>
