Experimental evaluation of cottonseed oil-camphor binary blends on diesel engine performance, combustion, exhaust and cyclic variance parameters

Abstract

This article studies the performance and emission characteristics of a compression ignition engine powered by blends of high viscous cottonseed oil and low viscous camphor oil. Three different blends are prepared with cottonseed oil and camphor oil on a volume basis (C30CSO70, C50CSO50 and C70CSO30). The experiments are carried out on a naturally aspirated, four-stroke, single-cylinder computerized CI engine. The experimental results convey that, at full load conditions, among the tested biofuels samples, the thermal efficiency of C70CSO30 surges to 3.4% and 7.8% more than C50CSO50 and C30CSO70. The CO, HC and smoke emissions of C70CSO30 were abated by 4.4% & 9.3%, 13% & 17%, and 24% & 29%, abated than C50CSO50 and C30CSO70. The NOx emissions of C70CSO30 were inflated by 10.435 and 19.49% compared to C50CSO50 and C30CSO70. Further, an increase in the volume of camphor oil in the blended fuel enhances the CI engine combustion and results in a boost in the in-cylinder pressure, in-cylinder temperature, net heat release rate, and cyclic variations.
