应用灰色系统理论分析研究大功率柴油机低负荷性能

Research on Low-load Performance of High Power Diesel Engine Using Gray System Theory

应用灰色系统理论研究了低负荷下进气涡流对TBD620V12柴油机燃烧过程的影响。结果表明,该型柴油机在低负荷下采用涡流气道进气,有利于缩短滞燃期,增加主燃烧阶段的燃烧百分数,达到了改善低负荷下燃烧的目的。

Using gray system theory, the influence of swirl inlet on the combustion process of TBD620V12 diesel engine under low load condition is studied. The results show that swirl inlet adopted on this type of diesel engine under low load condition is of benefit to shorten combustion delay period and increase the combustion percent in main-burnt period, so the goal of improving combustion can be achieved.
