查询词典 exhaust stroke

"In a two-stroke cycle, the compression and power strokes of the four-stroke cycle are carried out without the inlet and exhaust strokes, in one upstroke and one downstroke of the piston and one revolution of the crankshaft."

在二冲程循环中，只有四冲程循环的压缩和动力冲程，而没有进气和排气冲程，在活塞的一个上升冲程、一个下降冲程，同时曲轴旋转一周后完成。

This action could open an inlet valve for an intake stroke, or open an exhaust valve for an exhaust stroke.

这过程能使进气门在进气行程打开，或者排气门在排气行程打开。

"In the two- stroke -cycle, or two-cycle, engine, the intake and compression stroke s and the power and exhaust stroke s are in a sense combined. This permits the engine to produce a power stroke every two piston stroke s, or every crankshaft rotation."

在二行程发动机中，进气和压缩行以及作功和排气行分别合并在一起的，这使得二行程发动机每两个行程，即曲轴旋转一周，就完成一次工作循环。

"In the two-stroke-cycle, or two-cycle, engine, the intake and compression strokes and the power and exhaust strokes are in a sense combined. This permits the engine to produce a power stroke every two piston strokes, or every crankshaft rotation."

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。

There is plenty of torque on the compression stroke even with very low air pressure, but because there is only an exhaust port at the bottom of the stroke much of the power is wasted as the pistons are traveling up.

有大量的扭矩的压缩行程甚至非常低气压，但由于只有一个排气口底部的中风大部分的权力是浪费活塞旅行了。

"In a two- stroke cycle, the compression and power stroke s of the four- stroke cycle are carried out without the inlet and exhaust stroke s, in one up stroke and one down stroke of the piston and one revolution of the crankshaft."

在二冲程循环中，只有四冲程循环的压缩和动力冲程，而没有进气和排气冲程，在活塞的一个上升冲程、一个下降冲程，同时曲轴旋转一周后完成。

That is to say that the Intake stroke, Compression stroke, Power stroke and Exhaust stroke are one engine cycle.

亦即，发动机完成吸气、压缩、作功、排气一个循环冲程为一个周期。

When left when the test-drive after repair in shop main engine is adding this ship to 540r/min, supercharger occurrence asthma brace up phenomenon, rotate speed lifts slightly again, noise shakes very big, smoke evacuation temperature is normal, hair of on the high side of temperature of air inlet duct is very hot, as good as of smoke evacuation smoke constant, supercharger rotor rotate speed and the rotate speed of right leader supercharger that work normally comparative. 2 breakdown analyse this model diesel engine supercharger breathes heavily brace up the reason has the following sides. Bearing of 1 supercharger rotor damages, bring about on the low side of supercharger rotor rotate speed or wave motion, make inadequacy of compressor part air feed and diesel engine and its demand do not match, bring about air current not to stabilize generation to breathe heavily brace up. 2 diesel engine offers oil, match gas to time forbid, match gas, draw well time and disorder, bring about supercharger to breathe heavily brace up. 3 supercharger nozzle jams, cause smoke evacuation not free, circumfluence of exhaust stroke waste gas, enter jackknife of new energy of life with the below one stroke that take energy of life, produce air current to hit generation to breathe heavily brace up. Canal of 4 smoke evacuation jams, smoke evacuation not free, bring about waste gas circumfluence, hit generation of new energy of life to breathe heavily brace up. 5 jams into gas mouth, enter gas inadequacy, generation breathes heavily brace up. 3 trouble removal are based on above analysis, adopt the following measure to remove trouble.

该舰在厂修后试车时左主机在加至540r/min时，增压器出现喘振现象，转速再略升高，声响震动很大，排烟温度正常，进气管温度偏高发烫，排烟烟色无异常，增压器转子转速和正常工作的右主机增压器转速相当。2故障分析该型柴油机增压器喘振的原因有以下几个方面。1增压器转子轴承损坏，导致增压器转子转速偏低或波动，使得压气机部分供气不足和柴油机及其需求不匹配，导致气流不稳定产生喘振。2柴油机供油、配气定时不准，配气、发火定时紊乱，导致增压器喘振。3增压器喷嘴堵塞，导致排烟不畅，排气冲程废气回流，和下一进气冲程进新气重叠，发生气流冲撞产生喘振。4排烟管堵塞，排烟不畅，导致废气回流，冲撞新气产生喘振。5进气口堵塞，进气不足，产生喘振。3故障排除基于以上分析，采取以下办法排除故障。

"The engine uses two fired four-stroke cylinders under high pressure, which alternately exhaust into a low-pressure central expansion cylinder, which, in a fifth stroke, provides a further expansion process on the exhaust gases."

高低压指的是工作流体操作的压力，不是压缩比，中缸只有提供&膨胀&行程，并没有压缩点火燃烧等，因为这是汽油引擎，燃烧在小缸点火爆炸完的瞬间就结束了，排气进到中缸只是在继续减压膨胀，并没有做其他事

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。
