摘要
Abstract
In order to explore the evaporation process and mechanism of diesel-Jatropha biodiesel hybrid fuel and achieve the purpose of mixing biodiesel and diesel for stable combustion in diesel engine cylinders,Jatropha biodiesel and diesel were mixed at ambient temperatures of 723 and 873 K,and the proportion of Jatropha biodiesel was 10％,20％and 50％,respectively.The micro-explosion characteristics of diesel-Jatropha biodiesel hybrid fuel(JME10,JME20,JME50)were analyzed using thermocouple hanging drop technology,high-speed camera and Halcon software code processes droplet images.It was concluded that the diesel-Jatropha biodiesel with different mixing ratios and the droplet microburst intensity had a function relationship similar to parabola,and JME20 was the best mixing ratio.In this case,the increase or decrease of the mixing ratio would affect the droplet microburst effect,and the droplet microburst under this ratio had a minimum microburst delay time,which was conducive to the full mixing of fuel and air.The increase of ambient temperature can promote the improvement of fuel droplet microburst quality of JME10,JME20 and JME50,and can shorten the evaporation time.关键词
