Effect of Madhuca Indica Biodiesel Blends on Performance and Emission Parameters in a Single Cylinder Direct Injection Compression Ignition Engine

Increasing atmospheric pollution and gradual depletion of conventional fuels have resulted in hunting of alternative sources of fuels. Transesterified fuels have gained prominence due to their environmental friendly nature and engine hardware compatibility. In the current study, Madhuca indica biodiesel derived from non-edible feedstock was blended with diesel and used as fuel. The fuel properties and blend properties were found within the specification standards. Experimental investigations were carried out in Kirloskar 240 PE, single cylinder, and direct injection CI engine. Performance parameters like BSEC, BTE, EGT and Exhaust emissions such as UBHC, CO, NOx and Smoke density were evaluated to ensure the suitability of MOME blends. B20 blend was found to be a favorable alternative for CI engine due to increased BTE, reduced BSEC at higher loads and lower CO, UBHC, Smoke emissions over the entire operating range.
