Experimental Investigation Of A Diesel Engine Using Nerium Oil As Alternative Fuel

Abstract

The world’s fossil fuel reserves are depleting rapidly, according to the survey, 75% of fossil fuel production will be decreased in coming 11 years. Developing countries like India, invests heavily on imports of fossil fuels. Diesel fueled vehicles discharge significant amount of pollutants like CO, HC, NO_x, lead, soot, which are harmful for the environment. In this present work, four different blend ratios of Nerium oil esters in varying proportions viz., 20%, 30%, 40%  pure   Nerium oil  with diesel   are used.  for investigating performance and emission characteristics.

Experiments are carried out on a diesel engine using Nerium oil as alternative fuel which is a single cylinder, four-stroke, water cooled, and constant speed engine capable of developing a power output of 6.6 kW at 1500 rpm. Performance parameters such as brake power, specific fuel consumption, and thermal efficiency are calculated based on experimental analysis of the engine. Emissions such as carbon monoxide, carbon dioxide and unburned hydrocarbon are measured.
