By timely and spatially controlling the physical and chemical characteristics of the fuel at both port injection stage and in-cylinder direct injection stage, HCCI/DI stratified compound combustion is developed to combine the advantages of HCCI and conventional DICI on cycle-to-cycle basis and achieve clean and efficient combustion at full load ranges without misfiring and knocking.Firstly, three types of dual fuel including n-heptane/diesel, iso-octane/diesel and ethanol/bio-diesel a...更多re utilized to investigate the combustion and emission characteristics of HCCI/DI stratified compound combustion. The experimental results indicate that n-heptane/diesel HCCI/DI combustion presents a three-stage heat release consisting of HCCI low temperature heat release, high temperature heat release and diesel diffusive combustion.

本文提出的基于燃料设计与管理的HCCI/DI分层复合燃烧是一种将HCCI燃烧和传统缸内直喷压燃融为一体的新型燃烧方式，通过对燃料理化特性的设计和在预喷与直喷阶段从时间尺度和空间尺度上对均质和非均质混合气制备过程的控制和管理，在发动机的一个工作循环中将均质混合气的HCCI燃烧和非均质混合气的DICI扩散燃烧相融合，彻底消除了HCCI燃烧在小负荷失火和大负荷爆震的弊病，实现了发动机全负荷范围内的高效清洁燃烧。

In this paper, it is shown that the increment of the plasma confinement time without consideration of radiation losses is a good scale for evaluating the plasma confinement improvement during the L-H like transition induced by electrode bias in tokamaks, if the ratio of the radiation power to the total loss power in the transition changes evidently.

辐射下降表明进入等离子体的中性粒子通量减少。这是中性粒子再循环的减小而造成的。同时，边缘密度和边缘温度下降，中心温度上升，约束得到改善，能量约束时间增加。径向电场是控制托卡马克等离子体从L模过渡到H模的关键因素。如果径向电场足够强，极向ExB旋转产生很大的剪切，剪切能够抑制边缘湍流1j。
