| 摘 要： | 针对起动—停止技术的应用,采用了1台高速电机拖动Jetta1.6 L发动机,进行热机起动试验。分析了不同喷油量和不同拖动转速对起动时首循环燃烧情况的影响。结果表明,在其他边界条件不变时,随着起动初期喷油量的提高,缸内燃烧会显著改善;随着拖动转速的提高,滞燃期有所增大,缸内最高燃烧压力有所下降。对于本发动机,最佳喷油脉宽为11 ms,最佳拖动转速为600 r/min。

| Abstract: | For the start-stop technology,the heat starting experiments were carried out by using a high-speed motor to drag a Jetta1.6 L engine.The influences of different injection quantities and different dragging speeds on first cycle combustion performance were analyzed.The results show that,under other unchanged boundary conditions,the in-cylinder combustion is obviously improved with the increase of first cycle injecting quantity.With the increase of dragging speed,the ignition delay period increases and the max... |
