Analysis of Impact of Diesel Fuel/Biodiesel Blends on a Modern Diesel Combustion System Performance by Means of Injection Test Rig, Optical and Real SC Engine Experiments 2009-01-0484

An experimental evaluation of the impact of the diesel/biodiesel blends is presented in terms of engine performances and pollutant emission analysis. In-cylinder combustion evolution and injection law characterization were carried out on a single cylinder engine, on an optical single cylinder engine and on an injection test rig. Different diesel/biodiesel blends were tested at three operating points, representative of the NEDC cycle. Increasing the biodiesel percentage a reduction mainly in terms of smoke emission was observed. The engine performance as well as the other pollutant emissions were not substantially changed. Therefore this study confirms the benefits of the biodiesel use also on the current automotive engines, reducing simultaneously their environmental impact in terms of GHG and smoke emissions.
