Abstract: The conventional fuels are necessity for all the automobile machineries, due to deficiency of conventional energy sources need to search for alternative sources like biodiesels should give more impact to the automobile sectors. Biodiesel are clean energy, eco friendly, easily possible to produce from biomass. Alternative energy sources having more capable for solving environment aspects like reduce the pollution to the environment. This paper deals papaya seed oil used as feedstock, in this biodiesel produced by transesterification method using potassium hydroxide (KOH) as catalyst. This biofuel is used in four stoke, single cylinder, variable compression engine (VCR). The rated speed of the engine is 1500 rpm. This emission performance is analyzing for different nozzles with blends. Carbon mono oxide (CO) slightly increasing with load, Hydro carbon (HC) slightly decreasing with load, Carbon di-oxide(CO2) increasing with load. Oxygen (O2) is decreasing with load. Nitrogen oxide (NOX) and particulate matter is also increasing slightly with load.
