ABSTRACT:
A pilot burner for a device for burning off solid particles, especially soot particles, in the exhaust gas of internal combustion engines has a hollow-cylindrical mixture preparation chamber receiving a glow element and extending eccentrically thereto a hollow-cylindrical glow plug receiving chamber. The two chambers communicate with one another via an opening formed by piercing the chamber walls. A fuel inflow line discharges in the receiving chamber and an air supply line discharges into the preparation chamber. To improve the mixture preparation and largely avoid carbonization of the glow plug, the air supply line discharges into two inflow openings having a tangential direction; one inflow opening is located opposite the opening between the two chambers, and the other inflow opening is located near the end face of the preparation chamber having a mixture outlet opening. In obth inflow openings, the combustion air is introduced in the same direction.
