Background
Diesel engines (diesel engines) are widely used in the fields of transportation, agricultural machinery, engineering machinery, and the like due to their excellent power performance and economy. However, the diesel engine generates more particulate emissions, causes greater pollution to the atmospheric environment, and also poses greater threats to the health of residents.
A diesel particulate trap (DPF) is capable of trapping particulate matter, preventing the particulate matter from being discharged to the atmosphere. The DPF can accumulate particulate matters continuously in the using process, so that the exhaust back pressure is increased, and the normal work of the diesel engine is influenced. Therefore, the temperature of the particulate matter trapped in the DPF is generally raised by adding a catalyst and raising the temperature by injecting oil, so that combustible substances such as soot and organic matter in the particulate matter are oxidized to form gas and discharged to the atmosphere.
In the diesel engine using the biodiesel as fuel, the inorganic salt content in the particulate matters is high, and the particulate matters cannot be removed in the DPF in an oxidation combustion mode, so that the DPF can be blocked over time, and even sintering and other phenomena are generated in the regeneration process, so that irreversible damage is caused to the DPF.
