Abstract:
An exhaust system (16) of a diesel engine (10) has a diesel particulate filter (18) for treating exhaust gas. When trapped soot has accumulated to an extent that may affect performance of the filter, an engine control system (12) forces combustion of trapped soot by increasing exhaust back-pressure using a control device (20) such as a back-pressure control valve or vanes of a variable geometry turbocharger.
