Comparison of Particulate Matters in a Compression Ignition Engine under Mid-load Condition Fuelled with Diesel and Biodiesel fuel

In this study, the characteristics of particulate matters (PM) from diesel and biodiesel fuel combustion was experimentally investigated. The experiment was performed in a single cylinder common-rail compression ignition engine. The fuels were injected at -5 CAD (Crank angle degree) ATDC (After top dead center) with 80 MPa injection pressure. Size distribution of PM was measured by scanning mobility particle sizer (SMPS) and morphology of PM was studied by transmission electron microscopy (TEM). PM from biodiesel shows lower emission level and smaller primary particles.
