ABSTRACT:
An insulated fuel injection device, particularly for diesel engines, is provided for maintaining the nozzle spray hole temperature at a reduced level during engine operation whereby coking at the nozzle hole is prevented. The device comprises an elongated injection nozzle having a spray hole at one end thereof and an elongated hood covering the nozzle. The hood has a spray orifice therein which is aligned with the nozzle spray hole when the device is assembled. The interior dimensions of the hood and the corresponding exterior dimensions of the nozzle are such that a generally annular gap is presented between the hood and the nozzle, at least in the vicinity of the hole, and a quantity of heat insulating material is disposed in the gap adjacent the nozzle spray hole and the hood aperture.
