Characteristics of Particle Size distribution from a Diesel Engine with Emulsified Diesel

Abstract:

In this paper, particle number size distribution, total particle number concentration, nucleation mode particle number concentration and accumulation mode particle number concentration for pure diesel and emulsified diesel fueled in a turbocharged diesel engine were studied by experiments. The fuels used in the experiments were the pure diesel E0 and emulsified diesel E10, E15 and ED. The findings show that when emulsified diesel is fueled, particle number size distribution would show unimodal or bimodal log-normal distribution, and the maximum of the number is at 10-20nm. While compared to pure diesel E0 fueled, the nucleation mode particle number and volume concentration increases, the accumulation mode particle number and volume concentration decreases, however the total particle number concentration increases，and the total particle volume concentration decreases.
