Stroke,2 in 1 magneto, small size, compact structure.

四冲程，配置二合一磁电机，体积小，结构紧凑。

One interesting experiment at diversification by Jena occurred in the mid 1950's; Carl Zeiss Jena produced four variants of a model two-cycle diesel engine for hobbyist applications in model cars, planes, and boats!

二十世纪五十年代中期，耶拿东蔡发生了一件有趣的事：公司生产了一种作模型用的两冲程柴油机，供业余爱好者们制作车模、飞机模型和船模使用！

So the Woodman seized his axe, and with one stroke cut the Serpent in two.

因此樵夫缴获了他的轴，并且与一个冲程切开在二的蛇。

Omnibuses conglomerate in conflict—for ever desiring—(the clock asseverates with twelve distinct strokes that it is midday; light sheds gold scales; children swarm)—for ever desiring truth.

Omnibuses conglomerate conflict 为曾经渴望(the 的时钟asseverates 以十二个分明冲程，这是午间；光流洒金标度；孩子swarm)为曾经渴望的真相。

The results of this study indicate that changing the angle of the intake port has a profound effect on the flow field during the intake stroke of the engine cycle. For the case with the intake-exhaust valves canted at zero degree (the so-called vertical valves), the tumble ratio, swirl ratio, turbulent intensity, and turbulent kinetic energy in the direction perpendicular to the bisecting plane of the cylinder are at their highest levels than those obtained for the other cases. This effect is most pronounced after the compression stroke of the cycle. As a result of this study, it is observed that the behavior of the overall flow field from the intake to the completion of compression stroke has a major impact on the effectiveness of the mixing of fuel-air prior to the ignition of the engine cycle.

结果显示，改变进排气阀的倾斜角度对进气期间的流场变化有很明显的影响，其中以垂直阀(进排气阀倾斜0度)所得的 Y轴向(Y方向系垂直於将汽缸对分为二平面的方向)滚流强度、涡漩比、紊流强度、紊流动能等流场强度为最强；若以流体经活塞压缩后的流场特性进行探讨，所得结果显示压缩冲程对汽缸内流场的效应是不容忽视的；因此由进气到压缩过程结束的整体流场现象，才是影响引擎点火前的油气混合程度与燃烧品质的关键。

With CAD/CAM integrated modeling technology and NC programming manufacturing to develop cold box process casting technology of engine cylinder block and cylinder head of linear four-cylinder,two-air valve mid-position cam,four-stroke direct-jet combustion chamber,drying cylinder sleeve turbocharged and oil intercooled diesel engine in accordance with EUROⅢ standard of automobile tail gas exhaust.

运用 CAD /CAM一体化复合建模与数控编程加工技术，研究开发了符合欧Ⅲ汽车排放标准的直列四缸、二气门中置凸轮、四冲程直喷燃烧室、干式缸套涡轮增压和机油中冷式柴油发动机缸体缸盖冷芯盒铸造成形工艺。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
