FLAME GLOWPLUG FOR AN INJECTED AIR COMPRESSING COMBUSTION ENGINE, IN PARTICULAR FOR A DIRECT INJECTION AND SUPERCHARGING ENGINE

摘要

The invention relates to a flame-type heater plug for an air-compression fuel-injection internal-combustion engine, especially a direct-injection and superchargable internal-combustion engine. The heater plug includes a heater tube arranged in the course of a plug housing and protective tube and has an integrated first control coil at a level of passage orifices in the protective tube, heating coil and a second control coil arranged outside the protective tube at a side of the heating coil opposite the first control coil. A heater-tube portion which projects from the protective tube and is located in the flow path of the intake air in the suction pipe of the internal-combustion engine is provided in which the second control coil is arranged for further influencing the power of the heating oil.
