The Influence of Vehicle DPF on Diesel Performance and Emission

The influence of wall-flow ceramic DPF on diesel performance and emission was studied. In the experiment, the representative working conditions were selected to research the influence of DPF on soot, NOx emission, specific fuel consumption and fuel consumption under different amounts of filtering soot. The experimental results indicate that the DPF makes the specific fuel consumption a small increase, the soot and PM emission a remarkable decrease and the NOx emission a small rise. The soot, PM and NOx emissions all can satisfy the limit requirements of emission standard.
