visualization - Opis:
- It is one of the solutions to use biomass as fuel in order to realize a sustainable society and to reduce carbon dioxide emission .A single cylinder with supercharged and micro-pilot gas engine operated with four kinds of pyrolysis gas as fuel for cogeneration use. The effects of injection pressure and amount of diesel fuel on engine performance and exhaust emissions were investigated. The combustion periods of initial and main stages were determined from the analysis of mass fraction burned. The combustion process was also visualized with a colour highspeed video camera. Main results obtained in this study are as follows: When the amount of diesel fuel increased in the same injection pressure, smoke was exhausted. However, the smoke was reduced with higher injection pressure. The period of the initial combustion is almost the same even if injection pressure and amount of diesel fuel increases. Therefore, it is enough to ignite the mixture with small amount of diesel fuel. For the case with lower calorific gas, the period of main combustion was shortened owing to the combustion of diesel fuel when the amount of diesel fuel increases. When the mixture contains much hydrogen, the period of main combustion does not become small in higher injection pressure and larger amount of diesel fuel. On the other hand, when the mixture does not contain much hydrogen, the effect of diesel fuel becomes strong.
