改性生物柴油碳烟与NOx排放试验
Experiment on the Smoke and NOx Emissions of Modified Biodiesel
摘要
Abstract
Because of the poor oxidation stability and the high NOX emissions, biodiesel fuel was redesigned by adding anti-oxidants. The oxidation stability and viscosity of the biodiesel have been measured and analyzed. The engine experiment was conducted and it was fueled by biodiesel and BHA/biodiesel, NO., emission and smoke were measured. The mechanism of anti-oxidants to decrease the smoke, Nox emission was discussed. The results showed that BHA additive was a high effective antioxidant of biodiesel, the viscosity of biodiesel was decreased slightly; and the emission smoke and NO., was decreased significantly, especially at the high load condition. Anti-oxidants can restrain the high-temperature dissociation of long-chain fatty acid molecules during the combustion process, and it can promote the quenching effects of free radical. Also, it can change the " trade-off" tradition relationship between smoke and NO., emissions.关键词
