DIESEL INTERNAL COMBUSTION ENGINE WITH SOOT COMBUSTION APPARATUS

摘要

A diesel internal combustion engine with a soot filter in the exhaust system is equipped with a controllable soot burn-off device. The latter comprises a burner arranged in the soot filter and is operable with fresh air separately fed to the soot filter. In order to render the soot burn-off device useful for several purposes, this device is switchable to serve as a warm-up means which heats up the engine and or its running and operating media during or before operation.
