Cold start structure for multipoint fuel injection systems

摘要

Cold start structure (10) for a fuel injection system includes a fuel rail (12) constructed and arranged to receive a source of fuel. A plurality of fuel injectors (14) is provided with each fuel injector being mounted to the fuel rail to receive fuel. Each fuel injector includes an injector body (24) having an inlet (22) and an outlet (25) and valve structure (26) in the injector body movable between open and closed positions to control flow of fuel from the outlet. Heating structure (16) is associated with each fuel injector and includes a main body (18) mounted to a portion of the fuel rail and a heating element (20) mounted with respect to the main body and extending through the fuel rail, into the inlet of the associated fuel injector, and extending into the injector body of the associated fuel injector.
