Abstract
A fuel injection system for an internal combustion engine is provided that includes a fuel injector having an injector housing with first and second opposing portions. An injector passage extends between the first and second portions. A valve is disposed in the injector passage for selectively permitting fuel to flow from the first portion to the second portion. A fuel rail having a fuel passage includes a first opening receiving the first portion with the injector passage and fluid communication with the fuel passage. An intake manifold has a second opening receiving the second portion. A polymer layer extends from the fuel rail and intake manifold about at least a portion of the fuel injector sealing the first and second portions respectively to the fuel rail and intake manifold for preventing fuel from leaking from the fuel injection system. The injector wiring may also be integrated into the fuel injection system. The fuel rail may include a cavity for receiving wires that are connected to electrical contacts extending from the injectors into the cavity. A plastic material may be molded into the cavity to enclose the wires from the outside environment.
