Diesel engines are presently being used intensively in different sectors. The most important among the diesel engine sourced pollutants are NOx and soot emissions. These studies are both time and cost intensive for the researchers. There are in general different commercially used software in the market. The operating logic of these software is based on the 1st law of thermodynamics. In this study we conducted is standard B20 fuel modelled at different injection advances (16°KMA, 20°KMA, 24°KMA and 28°KMA) assessed with diesel fuel at standard injection advance with the Diesel-RK software in the program library. As a result, it is observed that the power loss has decreased by nearly 1-2% and the SFC increased by nearly 2% for the B20 fuel at 28°KMA compared with diesel fuel. It is revealed that there was an NOx emission increase of nearly 8% and a decrease of the soot emission by 3% to 33%.

INTRODUCTION Petrol fuels meet many of our basic energy needs in the industrial development, transportation, agricultural sectors and many others. These fuel reserves are being rapidly exhausted due to the excess consumption. The researches are also dealing with the reduction of the increase of pollutant emissions like CO 2 , HC, NOx, and SOx along with the limited usability of raw petrol [1]. Until present were the most studies with regards to the fight against the effects of the climate change focussed on the reduction of the greenhouse gas emissions or the conversion of these gases into lesser harmful ones for the climate change effects [2]. Along with this, the scarcity of traditional fossil sourced fuels, the pollutants generated by the combustion, their increasing costs and emissions turn alternative fuels more attractive [3,4]. Beside this, that hope giving digestive herbal oils are being used as an alternative to the expensive and exhausting fossil fuels is directing the researchers to such studies [5]. But many studies note on a worsening of
