Experimental investigation on the usage of processed oil as a source to fuel the diesel engine

Processed oil (HTO) is paraffin-based biofuels derived from many edibles and non-edible sources. HTVO shall be employed in engines as blended fuel with diesel or as neat fuel without or with any major modifications. However, the production of edible resources competes with food production. Hence, alternative non-edible and waste oil will be in high demand over the upcoming years to felicitate the significant replacement of fossil fuels. In this study, catalytic processing of non-edible and waste seed oil derived from custard seeds (HTCSO) was employed to produce fuels as a substitute for the transesterification process. The application of processed treatment will significantly increase in the transport sector in the coming years. This study investigates the extensive study on HTCSO on engine performance and emission patterns of a 4-stroke (Kirloskar AV1), 5.5 kW diesel engine. Ignition patterns were computed at different conditions by altering HTCSO percentage (25 and 50% volume) compared with diesel. Twenty-five and 50% volume of HTCSO blended with 75 and 50% of petrodiesel is referred to as HTCSO25D75 and HTCSO50D50, respectively. HTCSO/diesel blends show that the thermal brake efficiency (BTE), in general, was found to be increased, and brake-specific fuel consumption (BSFC) decreased with increased volume fraction of HTCSO in the blends. NOx CO, HC, and smoke opacity were found lower for all HTCSO blends than diesel at all load conditions. It shall be decided from the experimental research that HTCSO is a potential alternative to diesel fuel.
