Abstract
Steel fuel rails are provided with the mechanical components of a plurality of fuel injector valve bodies. The electronics for operating those valves are molded into an injector pack. The valve bodies are inserted into the passages associated with the injector pack such that the electronics are part of a single molded plastic portion. A corrugated seal is sealed to an outer portion of the passage on the injector pack. Thus, the present invention eliminates the number of connections for supplying fuel that needed to be sealed in the prior art. Further, the number of required assembly steps is reduced over the prior art.
Claims4
An air and fuel supply system for a vehicle engine comprising:
- a fuel rail including a plurality of valve bodies;
- an air manifold for delivering a plurality of separate air flows;
- and
- an injector pack having a plurality of passages for receiving air from said plurality of passages in said air manifold, and said injector pack having plastic molded passages to receive each of said valve bodies, said plastic molded passages including electrical controls for said valve bodies.
A method of providing an air and fuel supply system for a vehicle comprising the steps of:
- (1) providing an injector pack molded from plastic and including a plurality of electrical components for fuel injection valves;
- (2) providing a fuel rail including a plurality of injector valves;
- (3) inserting said injector valves into passages within said injector pack such that said injector valves are associated with said electronics in said injector pack.
