| 1. | Then diesel fuel oil is injected or sprayed into the cylinder at the end of the compression stroke . 然后在压缩冲程即将结束时,柴油燃料被喷射或被喷雾进入气缸。 |
| 2. | Exchange - compression stroke 换气压缩行程 |
| 3. | It was found that the compression speed and compression stroke are the two factors affecting the molding pressure most significantly 由模拟找出了压缩速度与压缩行程是两个影响成型压力极大的因素。 |
| 4. | It was found that the compression speed and compression stroke are the two factors affecting the molding pressure most significantly 由仿真找出了压缩速度与压缩行程是两个影响成型压力极大的因素。 |
| 5. | Using lower switch time , lower compression speed and higher compression stroke will result in lower cavity pressures 使用较短的切换时间、较低的压缩速度以及较高的压缩行程将产生较低的模安穴压力。 |
| 6. | This is the four - stroke cycle which is in common use . an alternative is the two - stroke cycle , which combines the exhaust and compression strokes into one 这就是常用的四冲程循环。另一种循环是两冲程循环,它把排气冲程与压缩冲程合并为一个冲程。 |
| 7. | When the engine runs in compression stroke and power stroke , the valves must close tightly on their seats to produce a gas - tight seal and thus prevent the gases escaping from the combustion chamber 当发动机处于压缩行程和做功行程时,阀门必须紧紧地关闭以产生一个不透气的气封,以防止气体逃离燃烧室。 |
| 8. | In this paper , the general theory and numerical solution procedure were described . by building a diesel modeling with vertical valves and a piston bowl , a whole cycle was calculated , which include intake stroke , compression stroke , expansion stroke and exhaust stroke 通过对带有进、排气门的柴油机进行计算,模拟了一个完整循环内进气道、气门和缸内气体流动的全过程。 |
| 9. | Simulation and the associated numerical algorithm on the injection - compression molding ( icm ) process were developed to understand processing characteristics by changing processing parameters including compression speed , switch time from injection to compression , compression stroke as well as initial cavity thickness and part thickness using disk parts 摘要射出压缩成型的仿真以及数值运算是要了解成型参数的改变,包括:压缩速度、射出与封装的切换时间、压缩行程等制程特性而创建的,同时也包含了初始的开模厚度以及使用在光盘片的成品厚度。 |
| 10. | On the basis mentioned above , another mathematical model for the supercharged diesel was set up . according to this model some results of simulation calculations were given . the characteristics of operation of the diesel in wet compression : including the excess air coefficient , the cylinder temperature at the beginning of compression stroke , the maximum temperature in the cylinder , the cylinder thermal load , the specific fuel consumption , and efficiency of diesel engine were obtained 在此基础上,又建立了增压柴油机湿压缩的数学模型,对喷水后柴油机的各性能参数,诸如过量空气系数、气缸进气温度,缸内最高温度、气缸热负荷、比油耗、热效率等进行了仿真计算,为增压柴油机进口加湿技术的研究提供了理论依据。 |
