异辛烷热氛围燃烧特性与运行范围的试验研究

Test Research of the Hot Atmosphere Inflammation Characteristic of Isooctane and Function Scope

在一台改装过的单缸发动机上进行异辛烷热氛围燃烧的试验研究。研究表明:在"活化热氛围燃烧"方式下,异辛烷的着火最好,指示热效率和NOx的排放最高。异辛烷热氛围燃烧可以有效的拓展HCCI燃烧的负荷范围。

The test research of the hot atmosphere inflammation of isooctane is carried out on a refitting single cylinder engine.The result shows that the fire of isooctane,indication thermal efficiency and emission of NOx are best by the method of activation hot atmosphere inflammation.The load scope of HCCI inflammation can be effectively improved by isooctane hot atmosphere inflammation.
