ABSTRACT:
A pilot burner for a device for burning off solid particles, in particular soot particles, in the exhaust gas of internal combustion engines has a hollow-cylindrical mixture preparation chamber receiving a glow element and a hollow-cylindrical glow plug receiving chamber extending transversely to it and communicating with it through an opening. A fuel inflow line discharges into the receiving chamber and an air supply line discharges into the preparation chamber. To improve mixture preparation and largely avoid carbonization of the glow plug, the glow plug is coaxially surrounded in the vicinity of its coil at a radial distance by a protective sleeve. The fuel inflow line ends at an orifice fitting that protrudes radially into the receiving chamber and discharges immediately in front of the protective sleeve.
