Performance and Emission Studies on an Agriculture Engine on Karanja Bio Diesel with Bio Fuel Enhancer Additive

Abstract

The idea of using vegetable oils as fuel for diesel engines is not new. With the advent of cheap petroleum, appropriate crude oil fractions were reined to serve as fuel and diesel fuels and diesel engines evolved together. In the 1930s and 1940s vegetable oils were used as diesel fuels from time to time, but usually only in emergency situations. Recently, because of increases in crude oil prices, limited resources of fossil oil and environmental concern there has been a renewed focus on vegetable oils and animal fats to make biodiesel fuels. Diesel engines have proven their utility in the transportation, agriculture, and power sectors in India. They are also potential sources of decentralized energy generation for rural electrification. Concerns on the long-term availability of petroleum diesel and the stringent environmental norms have mandated the search for a renewable alternative to diesel fuel to address these problems. In this study, performance tests were carried out on diesel engine with neat diesel fuel and biodiesel mixture. Biodiesel was made by transesterification process. Karanja oil was selected for biodiesel production. Fuel blends were tested in a single cylinder, direct injection, water cooled diesel engine (agricultural). The effects of B30,B30 with Bio Fuel additive and commercial diesel on the engine power, engine torque, BSFCs and exhaust gasses temperature were ascertained by performance tests. The influence of blends on CO, NOx,and CO2 emission were investigated. The experimental results showed that the use of Biodiesel improve the performance parameters and decrease the CO emission as compared to diesel fuel. Bio Fuel Enhancer(BFE) not only improve the performance and also increase fuel saving and reduce the NOx.
