查询词典 compression engine

An engine cyclic variation model has been built by using the residual gas temperature for the n-th cycle as the input of the model, through constant pressure intake process, adiabatic compression process, constant volume combustion process, adiabatic expansion process, adiabatic blow down process and constant pressure exhaust process to approximate the thermodynamic processes in the cylinder, finally the residual gas temperature for the (n+1)-th cycle can be estimated.

Based on the quasi-dimension combustion model, the emission model is set up in this dissertation. The NO emissions in different conditions of LPG engine can be simulated and calculated by the model. The calculated results show that the NO emissions are larger influenced by ignition timing and less influenced by compression ratio, finally, choosing a right coefficient of excess air will have great effect to reduce NO emissions.

本文在建立的准维燃烧模型基础上建立了排放生成模型，利用该模型对液化石油气发动机在变参数情况下NO的排放生成情况进行了模拟计算，计算结果表明点火提前角对NO的生成影响较大，压缩比对NO的生成影响较小，而选择合适的过量空气系数更是对降低NO的生成起着关键作用。

The results show that the compression ratio has a significant influence on the engine performance, combustion and emissions.

研究结果表明，压缩比对发动机性能、燃烧和排放有较大影响。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
