Performance and emission investigation of CI engine using blends of corn oil biodiesel and turpentine

Abstract

During the last five decades, the demand of energy and noxious exhaust emissions have grown rapidly, subsequently researchers are forced to find some substitute fuels to overcome this critical situation. The past scenario reveals that bio diesel can aid in minimizing the utilization of petroleum products and also assists in curtailing the fatal emissions from the tailpipe of the engine. In the current research, work experimental investigation was made on the performance and emission characteristics of CI engine using corn seed biodiesel blended with turpentine oil. Biodiesel was extracted from corn seed oil using transesterification process and blended with turpentine oil in 30%, 50% and 70% ratio by volume (CBT-30, CBT-50 and CBT-70). Afterwards, these blends were tested on a four-stroke diesel engine at varying load conditions. The results disclosed that at full load, an enhancement of 2.78% and 15% was observed for brake power and brake thermal efficiency respectively in comparison with conventional diesel when the engine was fueled with CBT-30. Brake Specific Fuel Consumption, Brake Specific Energy Consumption, Hydrocarbons, Carbon monoxide and Smoke Opacity were found to be decreased in relation with baseline diesel by using CBT-30 at 100% engine load. Consequently, diesel engine can be energized with CBT-30 fuel blend without any modification and improved performance and emission analysis can be achieved.
