Abstract

Effects of fuel injection timing on combustion and emission characteristics of a single cylinder diesel engine fuelled with diesel and diesel-propane blends were studied. The results show that the influences of fuel injection timing on the performances of the engine exhibited the similar trends for the diesel and diesel-propane operations. For a given engine load and speed, the maximum heat release rate and NOx emission decreased with the postponement of the fuel injection timing while the total combustion duration, CO, HC and soot emissions increased with advancing the fuel injection timing. For a given engine load, speed and fuel injection timing, the maximum heat release rate and NOx emission increased with the increase of propane proportion in diesel-propane blends. However, the total combustion duration, CO, HC and soot emissions decreased with the increase of propane proportion in diesel-propane blends.
