Integration of a diesel injection nozzle with the sheathed-element glow plug

摘要

A device (4') for the heating of injected fuel, integrated with the injection nozzle, for an internal combustion engine with compression ignition has an outer body (2) of electrically and thermally insulating ceramic and an electrically powered heating element (1') acting without contact on the injected fuel jet, the heating element (1') being arranged between the outer body (2) and a sintered body (5') forming the internal chamber (3) of the device (4') on an electrically insulating but thermally highly conductive ceramic material. <IMAGE>
