Abstract
A device for feeding and igniting in particular gasoline as fuel for the vaporizing burner of a heater, in particular a vehicle heater, is disclosed. The fuel evaporated from a porous body is mixed with combustion air and burned in a combustion chamber of the heater after being initially ignited by a glow plug. In order to simplify the design and improve the efficiency of the device, the glow plug is mounted in a pipe insulated from the outer wall of the combustion chamber and is radially surrounded by porous tubular body that projects beyond the free end of the glow plug into the combustion chamber. Combustion air is supplied in the radial direction to the porous body in the area of the free end of the glow plug and fuel is supplied in the radial direction to the opposite end of the porous body. The part of the porous body located outside the combustion chamber acts as a distributor and temporary reservoir when fuel is supplied.
