In the recent research, as a result of depletion of world petroleum reserves, considerable attention has been focused on the use of different alternative fuels in diesel engines. The present work aims to ensure the possibility of adding ethanol as an additive with animal fat biodiesel that is tested as an alternative fuel for diesel in a CI engine. In this study, biodiesel is obtained from waste pork lard by base-catalyzed transesterification with methanol when potassium hydroxide as catalyst. 2.5%, 5% and 7.5% by volume of ethanol is blended with neat biodiesel in order to improve performance and combustion characteristics of a diesel engine. The experimental work is carried out in a 3.7 kW, single cylinder, naturally aspirated, water cooled, direct injection diesel engine for different loads and at a constant speed of 1500 rpm. The performance, emission and combustion characteristics of biodiesel-ethanol blends are investigated by comparing them with neat biodiesel and standard diesel. The experimental test results showed that the combustion and performance characteristics improved with the increase in percentage of ethanol addition with biodiesel. When compared to neat biodiesel and standard diesel, an increase in brake thermal efficiency of 5.8% and 4.1% is obtained for BEB7.5 blend at full load of the engine. With the increase in percentage of ethanol fraction in the blends, peak cylinder pressure and the corresponding heat release rate are increased. Biodiesel-ethanol blends exhibit longer ignition delay and shorter combustion duration when compared to neat biodiesel. Optimum reduction in carbon monoxide, unburned hydrocarbon and smoke emission are attained while using BEB5 blend at full load of the engine. However, there is an adverse effect in case of nitrogen oxide emission.

<p class="02abstracttext"><span lang="IN">A small diesel engine is a machine that has high efficiency but causes a high level of pollution. The most widely used fuel so far is fossil energy which is unrenewable energy. The fruit of the Calophyllum inophyllum plant has great potential to be developed as alternative energy for small diesel engines. In this study, the test fuel used was D100, B100, E5, E10, and E15. The small engine diesel used TG-R180 Diesel with a compression ratio of 20:1 at engine turns 1500, 1800, 2100, and 2400 rpm, and the braking load at a constant prony disc brake is 1,5 kg/cm<sup>2</sup>. The result of the study using E10 fuel can improve engine performance and can reduce the opacity of the exhaust gas. The highest power in the D100 fuel at 2100 rpm is 8,06 PS. The highest thermal efficiency of E10 fuel is 50,29%. The use of Calophyllum inophyllum biodiesel (B100) can reduce exhaust gas opacity in small diesel engines when compared to the use of D100. E10 fuel has the lowest exhaust gas opacity rate of 4,1%.</span></p>

The growing environmental concerns and the depletion of petroleum reserves have caused the development of alternative fuels. Biodiesel and alcohols are receiving increasing attention as alternative fuels for diesel engines due to well oxygenated, renewable fuels. In this study, a single cylinder, naturally aspirated, direct injection diesel engine has been experimentally investigated using ethanol-blended waste cooking oil methyl ester. Various proportion of biodiesel-ethanol blends were used in stability test at the different temperatures from 10 °C to 40 °C in the increment of 10°C. Based on the stability tests and improvement in fuel properties, B90E10 (90% biodiesel and 10% ethanol) and B80E20 (80% biodiesel and 20% ethanol) were selected for this investigation. Test results revealed that the improved engine characteristics with the use of B9E10 especially in comparison with B80E20. Reduction in brake thermal efficiency by 3.8% and slightly higher brake specific energy consumption of 15.1% were observed with B90E10 when compared to diesel at 100% load condition. Carbon monoxide, unburnt hydrocarbon, nitric oxide and smoke emission of B90E10 were reduced by 0.09% by vol., 10 ppm, 187 ppm and 12.9%, respectively compared to diesel. B90E10 exhibited lower peak pressure of 70.5 bar, slightly longer ignition delay of 14.2 °CA, and combustion duration of 43.3 °CA was also observed at 100% load condition.
