Experimental Evaluation of Performance and Emissions of CI Engine Using Cottonseed Biodiesel with N-Butonal as a Additive

The present work concerns with the evaluation of performance and emissions characteristics of CI engine using cottonseed based biodiesel (B20) with fuel additive N-butonal at different concentration levels. In the experimental work it was observed that addition of N-butonal as additive improved the performance of CI engine and reduced the emission levels of NOx, CO, HC. Tests were also conducted the effect of inlet air preheating and results shows the significant improvement in the engine performance and reduction in the emission levels. Better performance and emission levels observed when the engine runs at air inlet temperature of 60°C
