Abstract
India is a country obsessed with fuel efficiency and petrol vehicles are no match to diesel engines. While Electric and hybrid vehicles do act as credible replacement option for diesel engines, reality is they won’t replace it anytime soon. This leaves consumers with no choice but to prefer a diesel car over the other options. And diesel engines are infamous because of the emissons they emit while combustion, and cause damage to health and environment. This calls for urgency of action on emissons of diesel engine till the other viable options become better. Another major problem is the shortage of conventional fuels especially diesel. In this paper, Ethanol is blended with Waste Cooking Oil Methyl Ester (WCOME) and this biofuel is used in a Kirloskar TV2 engine for experimentation which has been loaded from 0-100% for investigation and all the values were plotted on a graph for easy comparison. In total, three blends are used for experimentation which are Diesel, B20 WCOME (20% WCOME+80% Diesel) and B20 WCOME+15% Ethanol. Among the properties evaluated for the 3 blends the Brake Thermal Efficiency (BTE) improved by 10% and the Brake Specific Fuel Consumption decreased by nearly 14% indicating that the Performance of the engine is improved. The emissions of the engine has also decreased and this is indicated by the reduction of Carbon Monoxide, Particulate Matter (PM) and Nitrogen Oxides (NOx) coming from the exhaust gases with NOx reducing by almost 30%. The introduction of slight Ignition Delay and Heat Release Rate (HRR) increasing by 15% proves that the Combustion of the engine is also improved due to the addition of the blend. On the whole the Performance, Emission and Combustion characteristics of the TV2 Engine, is improved with utilizing Ethanol as Oxygenator additive.
