Method for regenerating a diesel particulate filter |
摘要 |
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.
