Research on Temperature Characteristics of DPF Regeneration Technology Based on Catalytic Combustion of Fuel Injection

The DPF regeneration technology of diesel engine based on catalytic combustion of fuel injection is introduced. The regeneration of the diesel particulate filter is completed by combining DOC and DPF, oxidizing unburned HC through DOC so that the temperature rose to 500~600°C, igniting particles. The use of air-assisted injection to ensure the quality of fuel atomization and the concentration of oxygen in exhaust. Take the YN4100QB-1A diesel engine as an example, the experimental research had been done on the diesel particulate filter and regeneration program, the temperature characteristics under different quantity of fuel injection is also evaluated.
