- Abstract
- The use of alternative fuels addresses the issues of: reducing dependence on unstable petroleum supplies, reducing harmful emissions, and using renewable energy sources. This thesis focuses on a comparative energy balance on a four cylinder turbocharged diesel engine operating on diesel and biodiesel fuels. Steady-state tests were run to experimentally determine how input energy in the form of fuel was appropriated throughout the engine. The transfer of energy was measured for losses to the engine coolant and exhaust, usable power output, as well as minor and unaccounted losses. The results showed that input energy from biodiesel was distributed 37.4%, 31.1%, and 29.6% to the major areas of coolant, exhaust, and power output, respectively. Similarly the input energy from diesel was distributed 37.5%, 31.4%, and 29.2% to the major areas of coolant, exhaust, and power output, respectively. It was concluded from an uncertainty analysis that there was not a statistically significant difference in these results. Future improvements to obtain distinguishable results are outlined.
