Abstract
A fuel injection system for an engine of a vehicle includes a throttle body and an elastomeric injection manifold coupled to the downstream end of the throttle body. The injection manifold defines a fuel injector socket. The fuel injection system also includes a fuel injector receivable by the fuel injector socket of the injection manifold and a fuel rail fluidly coupled to the fuel injector. The fuel rail supplies fuel to the fuel injector.
Claims16
A fuel injection system for an engine of a vehicle, the fuel injection system comprising:
- a throttle body having an upstream end and a downstream end;
- an elastomeric injection manifold coupled to the downstream end of the throttle body, the injection manifold defining a fuel injector socket and having a flat plate portion defining a plurality of fastener holes;
- a fuel injector receivable by the fuel injector socket of the injection manifold;
- and
- a fuel rail fluidly coupled to the fuel injector, the fuel rail configured to supply fuel to the fuel injector, the fuel rail having a fuel rail mounting arm;
- wherein, the fuel rail mounting arm is coupled to the plate portion of the injection manifold using one or more fasteners received by the fastener holes.
