Background

A Particulate trap (DPF) is a ceramic Filter installed in the exhaust system of a Diesel engine that traps Particulate emissions before they enter the atmosphere.

The particulate trap can reduce soot produced by the diesel engine by more than 9%. Exhaust back pressure is affected by a large amount of soot particles accumulated inside the DPF, so that exhaust gas is difficult to discharge, and the power and fuel economy of an engine are greatly limited. The engine control unit controls the engine to automatically clean and reduce the soot according to the signal of the exhaust gas pressure sensor, and soot particles accumulated in the DPF are burnt at high temperature. However, in the engine reduction process, only the soot in the DPF is reduced, and ash substances other than the soot are not reduced and decomposed at all, and these ashes are mainly derived from components in engine oil and fuel oil, and the ash cannot be combusted, so that the effective volume of the particulate filter is reduced, and the function of the particulate filter deteriorates after a certain period of time.
