Performance and emission characteristics of an indirect injection (IDI) multi-cylinder compression ignition (CI) engine using diesel/Argemone maxicana biodiesel blends

Abstract

In this study, the performance and emission characteristics of diesel engine fueled with diesel/Argemone biodiesel blends have been evaluated. An experiment was conducted on an indirect injection (IDI) compression ignition (CI) engine using diesel and diesel/Argemone biodiesel blends. The result shows that with an increase in Argemone biodiesel blend ratio (up to B30) the performance characteristics such as brake thermal efficiency, brake specific fuel consumption get improved and result in significant reductions in CO and HC emissions. However, an increase in CO₂ and NOx emissions was observed for all biodiesel blends. The blends showed deterioration in brake thermal efficiency and brake specific fuel consumption at partial loads and high rpm conditions. The maximum value of brake thermal efficiency of 33.57% was obtained for B30 at full load @2500 rpm.
