Title: Effect of Injection Pressure on the Performance Characteristics of Double Cylinder Four-Stroke CI Engine Using Neem Bio-diesel
Abstract: In the recent past, due to the depletion of fossil fuels, crude oil prices have been raised drastically due to which the researchers are urged to find suitable bio-fuels which might supplement the conventional fuels used in the present days. Bio-diesels is one of several alternative fuels designed to enhance the utility of petroleum, durability, and neatness of diesel engines. To satisfy this difficult and ruinous situation, Neem can go about as an ecological amicable elective feed-stock for bio-diesel production. This paper represents the effect of Neem bio-diesel and its blending with pure mineral diesel at different injection pressure on diesel engine performance to evaluate break-specific fuel consumption, exhaust gas temperature and thermal efficiency. A four-stroke double cylinder compression ignition engine performance parameters were measured. The experimental research is carried out using different biodiesel blends such as B20, B40 and B60 at different injection pressure 220, 240 and 260 bar. Based on the experimental research it can be stated that as the injection pressure increases, the brake thermal efficiency rises and specific fuel consumption reduces. It is observed that B40 (40% Neem bio-diesel + 60% diesel) has the most suitable performance characteristics. By comparing the performance at injection pressure 220, 240 and 260 bar it is observed that Maximum BTHE is obtained at 260 bar injection pressure with an increase of 8.4% at full load condition while relatively lower specific fuel consumption as compared to all the blends of bio-diesel and pure diesel among different injection pressure.
