PERFORMANCE AND EMISSION CHARACTERISTICS OF DUAL FUEL DI DIESEL ENGINE USING CASHEW NUT SHELL BIO DIESEL AND HYDROGEN AS FUEL

With augmented vehicle quantities during latest period have effected into immense claim through vestige energy. These have lead with expansion of vehicle via substitute energy that comprises gaseous energy, bio energy and vegetables oils as stimulate. Power through hydrogen becomes the prime prospects which wrap the upcoming stipulate of remnant energy scarcity. Hydrogen as a key substitute energy becomes a substitution through usual energy. With notable possessions, alike elevated flare rapidity, elevated calorific value stimulates usage of hydrogen energy like twin fuel manner in diesel engine. Present study investigates the overall performance and emissions of diesel engine fuelled through CNSL and hydrogen as dual fuel. The fuels have been tested under stationary, one cylinder, water chilled diesel engine. Here the hydrogen is added with B20 (20% CNSL and 80% diesel) fuel for different flow rate namely 4lpm, 8lpm and 12lpm. Engine test results showed that exhaust emissions are reduced and performance are improved by adding hydrogen fuel. The results showed that the addition of 8lpm H2 with B20 decreased the HC and CO emission compared to B20 and neat diesel fuel. The BTE and NOx increased for the above dual fuel mode. The NOx and exhaust gas temperature are increased for 8lpm H2 addition with B20 fuel.
