A method for regenerating a diesel particulate filter (10) in the exhaust gas system of a diesel engine (5) is disclosed in which particulate matter is burned by increasing the temperature in the diesel particulate filter (10). Regeneration is carried out in a coordinated manner by: switching on electrical loads; at least partially closing the EGR valve, while adapting the pilot injection to prevent combustion noise exceeding an acceptable level; discontinuing feedback of boost pressure control via variable turbine geometry, when such feedback is present; restricting the fresh air supply to provide a desired intake pressure (depends on the speed and load); lessening the intake restriction to increase the intake pressure when the operator demands increased power or when the air/fuel ratio falls below a predetermined minimum value; increasing fuel supply as a function of the intake pressure, the pedal position and/or the engine speed when the fuel supply is not automatically controlled in some other way; and injecting post fuel during the expansion stroke when operating temperature of catalytic converter has been reached.

Preferably, the extendable member is further constrained by the base member so that the extendable member is not permitted to rotate substantially about the axis. l.; US-5778666, 19980700, Cullen et al.; US-5792436, 19980800, Feeley et al.; US-5802843, 19980900, Kurihara et al.; US-5803048, 19980900, Yano et al.; US-5832722, 19981100, Cullen et al.; US-5842340, 19981200, Bush et al.; US-5865027, 19990200, Hanafusa et al.; US-5938715, 19990800, Zang et al.; US-5953907, 19990900, Kato et al., 060/274; US-5970707, 19991000, Sawada et al.; US-5974788, 19991100, Hepburn et al.; US-5974791, 19991100, Hirota et al.; US-5974793, 19991100, Kinagusa et al.; US-5983627, 19991100, Asik; US-5992142, 19991100, Pott; US-5996338, 19991200, Hirota; US-6012428, 20000100, Yano et al.; US-6014859, 20000100, Yoshizaki et al.; US-6023929, 20000200, Ma; US-6058700, 20000500, Yamashita et al.; US-6112575, 20000900, Cocconi, 073/023.31; US-6119449, 20000900, Kohler, 060/285; US-6128948, 20001000, Shi et al., 073/118.1; US-6148656, 20001100, Breton, 073/023.31; US-6205773, 20010300, Suzuki, 060/285
