EVALUATION OF CI ENGINE PERFORMANCE AND EMISSIONFUELLED BY DIESEL-MOSAMBI PEEL PYRO OIL BLENDED WITH COPPER OXIDE NANOPARTICLES

The day by day increase in the emission of pollutants into the environment coming from road transport and rail way transports, and depletion of natural resources and economic considerations are the main reasons for the development of alternative fuels to power internal combustion engines. To boost the engine performance, copper oxide nano particles were doped along with mosambipeel pyro oil–diesel fuel blend as additive. Diesel engine's performance and emission characteristics were studied for 20%, 40%, 60%, 80% and 100% of the maximum power output with the fixed engine speed of 1500 rpm mosambipeel pyro oil with neat diesel. copper oxide nano particles were added in three difference concentrations as., 100, 200 and 300 ppm levels in all the three samples of mosambi peel pyro oil – diesel fuel blends to study their effects on engine performance. All bio-oil properties were studied made on the pyro oil, called as MDC10 (10%MPPO+100PPMCuO+ 90D), MDC20 (20%MPPO+200PPMCuO+80%D) and MDC30 (30% MPPO + 300PPM CuO+ 70% D). Characteristics of a fuel for Diesel, MDC10, MDC20 and MDC30 were analyzed. The blending of pyrolysis oil and copper nano particles are by mixing of diesel fuel by volume. The flash point, fire point, viscosity, density of the oils was observed. The samples ofblended fuels were examined in a 1500 rpm single cylinder diesel engine for their performance as blended fuel. Engine test results showed that the performance for all MDC10, MDC20 and MDC30 related to diesel fuel. At the maximum power output, the brake thermal efficiency was found as 31.5% respectivelywith MDC10, and where as, it was 30.0% with diesel fuel. There is a slight reduction for the smoke, and NOx emissions, HC and CO emission slightly reduced the MDC10,as fuel compared to diesel fuel at all power outputs.
