Performance and NO x emissions of Mahua ester blends with pyrogallol antioxidant in a single cylinder diesel engine

摘要: Biodiesel has attracted research because of its environmental benefits and energy security. In this research, the suitability of using Mahua B20 biodiesel blend in a single cylinder diesel engine has been carried out. The performance characteristics such as brake specific fuel consumption, brake thermal efficiency and NO x exhaust emissions of B20 Mahua biodiesel with pyrogallol antioxidant by changing its concentration from 0 ppm to 750 ppm is examined and compared to regular diesel. The engine performance results reveals that minor improvements in brake specific fuel consumption and brake thermal efficiency is observed with considerable reduction in NOx emission at an optimum 750 ppm antioxidant concentration in comparison with B20 Mahua blend without antioxidant. Thus, Mahua B20 blend with antioxidant can be used to run diesel engine without any modification.
