The utility model relates to a system which is used for collecting and cremating particle matter to clean the waste gas of a diesel engine. The system comprises a diesel particle converter (DPC) which is provided with a casing and at least one filter core positioned in the casing. A waste gas channel extends from a diesel engine and passes through the DPC. A diesel oxidation catalyst (DOC) is positioned in the waste gas channel. The system is provided with at least one waste gas cooling device used for controlling the temperature of the waste. A feedback control system controls the temperature of the waste gas according to the pressure drop of the DPC, the temperature in the front of the DPC and the engine RPM. The system can be used as an after-treatment device of a diesel engine and a natural gas engine. |
