Performance and Emission Analysis of Vcr Engine using Bio-Diesel

A constraint for use as an alternative fuel for internal combustion engines is considered a viscosity of waste vegetable oil. In this experimental investigation, the viscosity of cashew nut shell liquid (CSNL), which is considered a potential alternative fuel, is reduced by blending it in different proportions with diesel, and its viscosity at different temperatures was analyzed and used as a fuel in a compression ignition (CI) engine. Performance and emission parameters at different loads were calculated using a single cylinder VCR engine and compared to diesel engines. A remarkable improvement in engine performance is indicated as the viscosity of the oil is reduced. With a substantial reduction in the exhaust gas temperature, brake thermal and volumetric engine efficiency improved. Reductions in smoke, NO2, CO and HC emissions are also suggested. The results show that a mixture containing 60 percent CSNL with diesel, which is heated to a temperature of 55 ° C, can be used as an alternative fuel without any modification of the engine.
