Crash protection barrier for a fuel rail system of an internal combustion engine

摘要

The present invention relates to a crash protection barrier for a fuel rail system of an internal combustion engine, and in particular to an engine component such as an inlet manifold having a crash protection barrier facing a fuel rail. The engine (101) comprises an elongate moulded plastic material fuel rail (106), the fuel rail having an elongate side (126) extending along the length of the fuel rail (106) and at least one fuel inlet (110), and at least one fuel outlet (122) for supplying fuel to a combustion chamber. The engine (101) comprises additionally at least one component (104) spaced apart from and separate from the fuel rail (106), said component having a side (120) that faces towards the elongate side (126) of the fuel rail (106) across a gap (127) between the fuel rail and said component (104). A moulded plastic barrier (113) is joined to and extends across the side (120) of the component (104) facing the elongate side (126) of the fuel rail (106). The barrier (113) has at least one bar (116) spaced laterally from said side of the component, the or each bar (116) being joined to said component by at least two webs (118) of moulded plastic material that extend diagonally between the component (104) and the or each bar (116).
