Background
The diesel vehicle exhaust system generally adopts an SCR-selective catalytic reduction system or urea catalytic reducer, a DOC-diesel oxidation catalyst and a DPF-particle catcher, and is combined in the exhaust system, so that the emissions of NO, HC, CO and PM particles are effectively reduced. The DOC technology uses a catalyst containing noble metals to further oxidize HC, CO, NO and volatile components on the surfaces of particles in exhaust gas, thereby reducing the amounts of HC, CO and PM, and the DPF is a filter mainly used for capturing particulate matters, i.e., PM, in the exhaust gas.
However, after the system works for a period of time, PM particles are accumulated in the filter core of the component, the power of the vehicle is seriously affected, and how to clean PM microparticles in the component periodically and regenerate the component of the system are a great problem. There are several common practices: 1. a heating member is provided in the filter, and secondary air is supplied when the heater heats at a high temperature to burn off particles retained on the filter element. 2. The vehicle is parked in a clear place far away from a gas station, the vehicle is refueled to the limit, and the high temperature of the exhaust pipe is used for burning and removing the particulate matters. 3. The vehicle is driven to a repair shop, the tail gas emission system is disassembled, the special equipment is used for manually purging the blocked particulate matters in the DPF, the DPF is put into the application equipment for cleaning and drying, and the DPF is reinstalled on the vehicle for use, so that the whole cleaning process is completed for more than about one day. The scheme has high cost, is not environment-friendly and takes time. In addition, the improvement of the exhaust system affects the power of the vehicle, so how to improve and strengthen the power of the vehicle is also an important subject.
