An experimental study on transesterification process and emission analysis of diesel engine propelled with Capparis spinosa biodiesel

This work involves a detailed study on the transesterification process of waste and non-edible seed oil derived from Capparis spinosa (CSBD) to fuel research diesel engines. The positive claim of employing non-edible seeds shall reduce fossil fuel usage. This work examines the study on CSBD on transesterification and the emission patterns of a 4-stroke research diesel engine. Emission patterns were calculated in various circumstances by changing CSBD percentage (10 and 20% volume) and diesel. Ten and 20% vol of CSBD blended with 90, and 80% of petro-diesel is referred to as D90CSBD10 and D80CSBD20, respectively. Results revealed that the CO, HC, and smoke opacity were lower with a slight increase in NO emissions for all CSBD blends than diesel. Hence, this study concluded that the fuel obtained from Capparis spinosa oil is a viable alternate to diesel.
