Kurzfassung:
A China-V Heavy-duty diesel engine fueled with blends of 5%, 10%, 20%, 50% waste cooking oil biodiesel and diesel (marked separately BD5, BD10, BD20, BD50), pure biodiesel (BD100) and pure diesel (D100), was tested on full load speed characteristics and 1400 r/min and 2200 r/min load characteristics to study influence of biodiesel fuel and engine conditions on particle size distributions and particle number concentration. The results show that when fueled with blends containing less than 50% biodiesel, the particle number concentrations show single peak distribution curves (nucleation mode), for the pure biodiesel, particle number concentrations show bimodal distribution including nucleation mode and accumulation mode on full load speed characteristics and 1400 r/min and 2200 r/min load characteristics; on full load speed characteristics, for BD100, the peak of particle number concentration of BD100 is lowest, compared with D100, it is about one order of magnitude lower; on 1400r/min load characteristics, with the biodiesel proportion increasing, the number of nucleation mode and accumulation mode particles decreases; on lower than 1800 r/min full load speed characteristics and 1400 r/min and 2200 r/min load characteristics, with the biodiesel proportion increasing, the particle number concentration decreases.
