摘要

据实测的喷油器针阀升程和示功图

对一台单缸、直喷式柴油机燃用FischerOTrop sch ( FOT) 柴油时的燃烧放热规律进行了计算

并系统分析了其燃烧特性. 研究结果表明:与0 号柴油相比

FOT 柴油的喷油延迟角和喷油持续期稍长

滞燃期平均缩短了1817 %

预混燃烧放热峰值平均降低了2618 %

扩散燃烧放热峰值较高

快速燃烧期较短

燃烧持续期相当;燃用FOT 柴油时的最高燃烧压力略低

最大压力升高率显著降低

燃烧噪声和机械损失较小

有效燃油消耗率和有效热效率得到了改善.

Abstract

On t he basis of t he recorded in2cylinder pressures and injector needle lif t s

the combus2 tion characteristics of an unmodified single2cylinder direct injection diesel engine operating on F2T diesel f uel are analy-ed and compared wit h t hose of conventional diesel f uel operation. The result s show t hat F2T diesel f uel exhibit s a slightly longer delay of injection and duration of injection

an 18. 7 % average shorter ignition delay

and a comparable total combustion duration when com2 pared to t hose of conventional diesel f uel . Meanwhile

F2T diesel f uel displays a 26. 8 % average lower peak value of p remixed burning rate and a higher peak value of diff usive burning rate. In addition

t he F2T diesel engine has a slightly lower peak combustion pressure

a far lower rate of pressure rise

and a lower mechanical load and combustion noise t han the conventional diesel en2 gine. The brake specific f uel consumption is lower and t he effective t hermal efficiency is hi
