Performance analysis of cotton oil soapstock biodiesel diesel blends for compression ignition engines

Abstract

Transportation and agricultural purposes diesel engines are imperative contributors to pollution in the India. EPA standards and other environmental standards have deliberated strict rules for fuel producers and engine manufacturers. Currently, the oil prices are increased day by day and the country is craving for petroleum product from other countries which is pushing to produce renewable fuels to supply the recent demand. Consumers that choose to use these blends can also take advantage of the lubricity of biodiesel. The agricultural industry is provided an opportunity to utilize an agricultural byproduct by using cottonseed oil biodiesel as a fuel supplement, as well as acting as an agent in the push toward becoming less dependent on non-renewable energy sources. Biodiesel is a renewable fuel which can be blended with diesel. The impact on engine performance, exhaust emissions and combustion characteristics are significant to recognize the biodiesel from various feedstocks. The aim of this work is to examine the engine performance, exhaust emissions and combustion characteristics using cotton soapstock oil in unmodified single cylinder diesel engine rated 5.2 kW. And also finite element analysis is employed to examine the performance of the single cylinder engine operated with biodiesel through simulation using Ansys V15 tool.The indicated thermal efficiency (25.84%) of the B2 blend was significantly higher when compared with other blends as well as conventional diesel. The exhaust emissions of biodiesel blends such as HC, NOx and CO are reduced while comparing with conventional diesel. Carbon monoxide emissions are raised by around 8% using B4 and by around of 12% using B6. The data provides support for using biodiesel as a supplemental fuel for nonroad diesel engines. newline
