Fuel injection device for direct fuel injection engine

摘要

A fuel injection device for a direct fuel injection engine is equipped with a fuel distribution pipe assembly (30) for distributing fuel to fuel injectors (22) which comprises a main fuel distribution pipe (33) extending in a longitudinal direction of the engine (1) and discrete fuel distribution pipes (34) branching off from the fuel distribution pipe (33) and leading to the fuel injectors (22), respectively, and is installed to one side of a cylinder head (2). The main fuel distribution pipe (33) is offset from the longitudinal axis (y) of the fuel injector (22) on a side remote from the intake ports in a direction perpendicular to the longitudinal direction of the engine (1) and the discrete fuel injection pipes (34) are secured to the cylinder head (2) at locations between the longitudinal axis (y) of the fuel injector and the main fuel distribution pipe (33).
