Abstract
[Abstract]: This dissertation analyses the use of biodiesel in the agricultural industry and the performance of biodiesel when used as a replacement fuel for conventional diesel. The performance characteristics that are focused on are the production of the greenhouse gas oxides of nitrogen and the fuels suitability for use in stationary engines. A computer model is developed to simulate the formation rate of nitric oxide (the main component of oxides of nitrogen) and analyse the affects of using biodiesel instead of the conventional diesel. It was found that biodiesel produces a higher initial formation rate of nitric oxide for the same temperature and has a higher adiabatic flame temperature across all the equivalence ratios analyse. It is also found that the characteristic time increases as the compression ratio of an engine increases, and increases as the temperature of the cylinder contents increases. From other experimental work it is found that biodiesel and biodiesel – diesel blends produce similar power outputs compared to the conventional diesel fuel. From these experiments it was also found that biodiesel lead to higher amounts of oxides of nitrogen being produced, but lower amounts of carbon monoxide and carbon dioxide. From these results it was established that biodiesel is a effective replacement for conventional diesel, with the formation of oxides of nitrogen possibly reduced with the retarding of the fuel injection timing to an optimal level, which should also reduce the brake specific fuel consumption as well as increasing the efficiency and power generated from the engine.
