柴油喷雾贯穿距影响因素灰色关联分析
Gray relational analysis for effect factors of diesel spray penetration length
摘要
Abstract
Due to the important effects of fuel injection,atomization,evaporation and mixing process with air on combustion and emission characteristics of engine,the main feature size of penetration length of diesel spray was taken as research object.The effects of injection pulse width,injection pressure and back pressure in constant volume bomb on diesel spray were experimentally investigated by schlieren imaging technology.The impact of three factors on spray penetration length was also analyzed by gray relation theory.The results show that the spray penetration length is decreased with the increasing of back pressure under the same injection pressure and pulse width,while it is increased with the increasing of injection pressure under the same back pressure and injection pulse width.The injection pressure has the greatest impact on spray penetration length with less effects of back pressure and injection pulse width.关键词
