this air improves the atomization of fuel coming from the low-speed port . 這些空氣改善了從低速出口噴出的燃料的霧化。
the action of electrostatic on the atomization of fuel is investigated 研究了充電電壓對燃料霧化特性的影響。
it is necessary to study the spray in engine cylinder, for the performances on power output, thermal efficiency and emissions of diesel engine are directly influenced by the atomization of fuel 柴油機缸內(nèi)燃油的霧化情況直接影響著發(fā)動機的動力性、經(jīng)濟(jì)性和排放水平,研究燃油的霧化因而具有極大的現(xiàn)實性和緊迫性。
in this work, the macroscopical characteristics of diesel and diesel / lpg sprays are studied through using a digital camera with a high spatial resolution . based on processing technique for digital image, the droplets photographed, which are at the spray edge, are studied . after a comparison of the characteristics of sprays for different fuels, such as diesel, blend fuels of diesel and lpg with different weight fractions, it is shown that flash-boiling injection ( fuel containing dissolved gas ) is good for the atomization of fuel 本文對柴油和柴油lpg混合燃油的噴霧的宏觀特性采用高分辨率數(shù)碼相機進(jìn)行測量,并運用數(shù)字圖像技術(shù)處理了數(shù)碼相機捕捉到的處于霧束外沿的粒子,通過比較純柴油和不同lpg比例混合油的霧化性能,表明溶氣噴射(閃急沸騰)有利于噴射油滴的霧化。
