Pressurized fuel i.e. petrol, injecting circuit for e.g. petrol engine, of motor vehicle, has injection duct to connect outlet orifice of pressurized fuel collecting tank with injection unit, where duct and tank are formed as single piece

摘要

The circuit (26) has an injection duct (28) for connecting an outlet orifice of a pressurized fuel collecting tank with an injection unit (22). The injection duct and the collecting tank are formed as a single piece, where the collecting tank realized from a metallic alloy comprising aluminum and cast-iron. The collecting tank has a hollow transversal cylindrical tube and a fixation flange (58) to fix the circuit on an element e.g. cylinder head cover, of a direct injection type combustion engine. The tank and the duct have a vertical longitudinal section and a circular section, respectively.
