ABSTRACT:
A number of fuel injectors are mounted on an elongated carrier that is inserted endwise into an open end of an elongated hole in a member such as a tube or an engine manifold. The fuel injectors' nozzles are received in sealed manner in holes extending through the wall of said member. A keeper also inserted endwise through the elongated hole in the member keeps the carrier in place. In one embodiment, electrical lead wires extend from the fuel injectors along the carrier to a connector on the exterior to provide for the fuel rail assembly to be electrically connected by a wiring harness to the engine management computer. In another, the injectors are connected to the connector by means of an electronic circuit board assembly that is mounted on the carrier. The electronic circuit board assembly contains circuitry that is programmed to secure the proper dynamic calibration of the injectors over their entire dynamic operating range.
