Fuel injection device for internal combustion engine

Abstract

Abstract PURPOSE: To suppress fuel temperature rise so as to effectively utilize a space in an engine room by utilizing a side branch type resonator for reducing an intake noise also as a thermal insulating member. CONSTITUTION: A fuel distributing supply part 13 composed of a fuel supply pipeline 14 and an injection valve connecting part 15 is integrally arranged to an intake manifold 12, and a resonator 17 is attached to the fuel supply pipeline 14. This resonator 17 is formed by integrating a connector part 18 for feeding electricity to a side flow type fuel injection valve 16 with a resonator part 19 for reducing an intake noise, attached to a resonator mounting part 14D. The resonator part 19 functions also as a thermal insulating member while reducing the intake noise so that fuel temperature rise can be suppressed.
