PCT No. PCT/EP86/00058 Sec. 371 Date Oct. 8, 1986 Sec. 102(e) Date Oct. 8, 1986 PCT Filed Feb. 4, 1986 PCT Pub. No. WO86/04641 PCT Pub. Date Aug. 14, 1986.In a process for the automatic regeneration of a soot filter in an exhaust line (11) of a diesel engine in a passenger vehicle, a throttle valve in the intake line is controlled by the following system logic. The speed (n) of the diesel engine (1), the back pressure (PVF), measured upstream of the soot filter (12), and the exhaust temperature are each compared with preset lower limit values (ng, PGU, TGU). The back pressure (PVF) is additionally compared with a preset upper limit value (PGO). When all measured variables lie above the limit values mentioned, the control device generates a signal "close throttle valve". The two limit values for the pressure, (PGU and PGO), are displaced with the speed (n) in accordance with their respective alteration. |
