It is rapidly expanding around the world, making it imperative fully to understand the impacts of biodiesel on the diesel engine combustion process and pollutant formation. Biodiesel can blend with diesel in any ratio, and the air pollutant emissions decreased with biodiesel content in fuels. However, biodiesel blend fuel reduced the diesel engine power output. Blend fuels containing 10, 20, 30, and 40% by volume of soybean biodiesel were used. ECOM-AC gas analyzer was used to measure the concentrations of CO, CO2, and NOX in the exhaust gas. The sampling of exhaust gas was taken in extension section of the exhaust pipe without catalytic converter. The engine experimental results showed these exhaust emissions were reduced for biodiesel blended fuels. However, additive for biodiesel was a slight increase in oxides of nitrogen (NO X) emission. From these statistical models, there are influences of biodiesel blend ratio, engine speed and throttle position. Statistical optimization methodology was used to investigate the mutual interaction between the emissions and engine performance. In this study, the suitable biodiesel blend ratio was about 2 - 7 %, it was the balance between exhaust emissions and engine performance. |
