Cerium oxide nano additive impact of VCR diesel engine characteristics by using Ginger grass oil blended with diesel

Abstract

Diesel driven engines are the driving force behind industrialisation and commercial transportation till date. A world without diesel fuel would be a very difficult place to live in. The alarming depletion of this fuel resource, its ever increasing price and the amount of environmental pollution caused by its products of combustion has opened up wide opportunities for the search for an alternative fuel resource. Researchers have been exploring the idea of evaluating different plant and vegetable oils as a replacement of diesel for some time now. Based on this, an attempt has been made to investigate Ginger grass oil as a substitute for diesel fuel without making any modifications to the engine structure. The experiment was conducted on a 1500 rpm, four stroke, single cylinder, diesel engine. Cerium oxide nano-additive was added to the blends of Ginger grass oil with diesel and its effects on the Efficiency, and Exhaust Emissions were examined. The experiment yielded better values of Brake Thermal Efficiency and low Specific Fuel Consumption with B10 and B20 samples, while the B40 blend showed lower NOx emissions at all loads. The HC content was found to increase with the increasing quantity of Ginger grass oil in the blends.
