Experimental investigation of performance and emission characteristics of CI engine fuelled with linseed oil blended diesel fuel with camphor as additive

The paper investigates the performance and emission characteristics of CI engine fuelled with linseed oil blended diesel fuel with camphor as additives. Experiment was conducted on the single cylinder four stroke water cooled diesel engine at constant speed of 1500 rpm for different operating loading conditions. Diesel, B10 linseed oil (linseed oil 10% and diesel 90%), B10 0.5% camphor and B10 1% camphor were tested. The result showed that brake thermal efficiency was found higher for diesel when compared to blended fuel at lower load conditions but brake thermal efficiency for blended fuels becomes higher as the load increases. Addition of camphor was found with providing good significance in brake thermal efficiency. Blended fuel was found with higher brake specific fuel consumption when compared to diesel because of lower calorific value. Exhaust gas temperature for blended fuel was found higher than diesel because of higher viscosity. Emission parameters such as CO, CO2, HC was found higher for blended fuel than diesel. NOx emission was also found higher for blended fuel than diesel. Addition of camphor showed a decrease in all the emissions at all loading conditions.
