摘要：Performance and emissions from a constant speed single cylinder diesel engine was observed with different kinds of fuels blends like diesel-ethanol, and diesel-palm stearin methyl ester. The engine setup was modified to operate in different modes like naturally aspirated condition, supercharged condition and with exhaust gas recirculation (EGR). The air fuel ratio was predicted from exhaust emission data using correlations and the particulate matter (PM) was estimated from smoke data. Fuel air equivalence ratio values of the engine at different operating conditions have been compared. Engine is operated with higher fuel air equivalence ratios with EGR. Particulate matter emissions were considerably reduced with ethanol-diesel, biodiesel-diesel blends in comparison to pure diesel. With EGR rate the particulate matter emissions are increased. An EGR rate of 10% will be best for the present engine which can give better trade-off among HC, NOx and PM.
