Experimental Investigations on Performance of Diesel Engine with Neem Oil, Cow Ghee and NFA Blends With Atomized Diesel

The depletion of the world petroleum reserves and the increased environmental concern had stimulated the search of alternative fuel which is to reduce the harmful substances in emissions and increase the performance of the engine at the same time. The feasibility of using edible oils such as neem oil and cow ghee with diesel as fuel for CI engine is be studied. The experimental investigation was done on single cylinder water cooled diesel engine using various proportions of blends as fuel for engine and use ultrasonic vibrators to turn the diesel from liquid form to mist form, so that the fuel atomizes rapidly when atomized. Performance of engine is calculated by running engine at different loads. Brake Thermal Efficiency, CO emissions (ppm) and fuel combustion are the deciding responses of the performance of the engine in this paper.
