摘要


由於減低CO2溫室氣體排放量和對石化燃料的依賴已成為本世紀的話題,2007年底植物性油脂的需求量已迫近其總生產量。為了使生質柴油在使用上的經濟性更加良好,本研究利用生質柴油具有的高密度、動力黏度、含氧量和十六烷值等的特性,來探討燃料噴射壓力對引擎性能及廢氣排放等的影響性。經實驗結果顯示,較原柴油引擎燃料噴射壓力(200kg/cm2)低之燃料噴射壓力(160kg/cm2),在不影響原引擎性能的條件下,能減低排氣溫度、NOx濃度及HC濃度的排放,但BSFC值及smoke濃度會增加。另較原柴油引擎燃料噴射壓力高之燃料噴射壓力(250kg/cm2),則除影響引擎性能外,又會減少BSFC值、smoke濃度及NOx濃度的排放,但HC排放濃度會增加。使用B100燃料可適當的提高燃料噴射壓力,其對引擎性能和廢氣排放是有幫助的。

For decreasing CO2 greenhouse gas emission and reducing the dependence of fossil fuel, it has become a very serious topic in this century. The demand quantity for vegetable fat at the end of 2007 has been approached total production quantity of the year. In order to enhance economic benefits for biodiesel, utilizing its characteristics of high density, kinematic viscosity, oxygen content, and cetane number investigate the effect of fuel injection pressure to engine performance as well as exhaust gas emissions. The experimental results demonstrated, that using lower fuel-injection pressure (160kg/cm2) than the original engine (200kg/cm2) as well as based on no influence on the engine performance can reduce exhaust gas emission, the concentration of NOx, and the concentration of HC, but the value of BSFC and the concentration of smoke are increased. Using higher fuel-injection pressure (250kg/cm2) than the original not only affected the engine performance, but also decreased the value of BSFC, the concentration of smoke, and the concentration of NOx. But the concentration of HC, it is increased. That using B100 fuel can properly increase fuel injection pressure, because engine performance and exhaust gas emission are improved.
