Abstract
The paper presents biodiesel production based cat-fish oil at Institute of Industrial Chemistry and summarized findings of research activities on utilization of biodiesel B5 in engines and in transport vehicles at Lab of Internal Combustion Engine, Hanoi University of Technology. Impacts of biodiesel B5 on engine performance, exhaust emissions and durability were investigated and discussed. To target these, a number of vehicles and engines were experimented on chassis dynamometer and on engine test-bed, respectively. Findings of the comparative experiments, durability tests and field tests show positive impacts of biodiesel B5 on engines in general, except the increasing of NOx. The engine’s power and fuel consumption were improved up to 1.33 and 1.39, respectively. Exhaust emission components HC, CO and PM were reduced in turn up to 14.46%, 12.94% and 2.57%. While NOx emission component was increased up to 3.80% due to high temperature resulted by better combustion process. In addition, no damage to the engine parts was found during the tests with biodiesel B5. The engine fueled with biodiesel B5 showed smaller changes in all parameters during the durability test compared with the engine fueled with diesel. These findings are very important to ensure the utilization of this alternative fuel in engines.
