气门

Major production and distribution piston rings and valve seat.

主要生产和经销活塞环及气门座圈。

After the matching relationship between inlet valve and piston trajectory was analyzed, a dual crank shaft mechanism was designed, and method of adjusting the valves between their on-off time and continuance time was obtained.

分析了进气阀与活塞运动之间新的匹配关系。设计了复曲轴连杆结构，并得到调节进排气门的开关时刻与持续时间的方法。

The function of air filter is to filter the dust and impurity from the air entering into engine, to ensure the cleanliness of the air inside of cylinder; to decrease the worn between cylinder and piston, piston bodies, and valve components.

空气滤清器的作用是把进入发动机的环境空气中的灰尘和杂质滤掉，从而保证气缸内的空气清洁，减少气缸与活塞之间，活塞组本身，以及气门组零件的磨损。

And the first research for the variation of valve seat velocity, valve impulsive force and valve jump with the cam turning speed, the structures and the different cam profilers have been engaged in, such study work had not been done before about the valve train.

气门落座特性参数的变化规律在应用单质量模型和有限元模型时是很难得到的，而利用多质量模型可以很容易得到，因此澄清了以往的一些模糊认识，也得出了一些很有价值的结论。

Surface pockmarks on the rod of gas valve of 4Cr10Si2Mo steel frequently occur after accurate grinding.

4Cr10Si2Mo钢气门杆部在精磨后经常会出现&麻坑&。

Compact pentroof combustion chambers and high-strength pistons that are resin-coated to reduce friction, low-tension piston rings and a low-friction valve train that uses roller rocker arms also are important features of this engine, as is an Acoustic Control Induction System that changes the length of the intake manifold runners based on engine speed and throttle opening.

紧凑pentroof燃烧室和高强度的活塞是树脂涂层以减少摩擦，低张力活塞环和低摩擦气门，使用滚子摇臂也是这个引擎的重要特色，是一种声学控制感应系统这改变了进气长度发动机转速和节气门开度为基础的多方面的选手。

A charge of the pneumatic valve engine inspections resumed devices necessary high pressure bottle, if necessary, must add high-pressure air.

1位负责检查引擎气门的气动回复装置所需的高压力瓶，必要时必须补充高压空气。

The HEMI new Variable Valve Timing improves fuel economy in two ways. First, it reduces the engine pumping work by closing the intake valve later.

新的HEMI VVT可变时气门）在两个方面改善了耗油性能：第一，迟一点关闭进气阀来减少了发动机的泵油。

Simulation results show that the load control method with variable event timing can effectively decrease the pumping loss at engine partial load condition up to 57%, and the brake specific fuel consumption is improved to 5.63%.

结果表明，采用可变气门开启持续期负荷控制方式可以有效降低汽油机部分负荷泵气损失，最大降低幅度达到57%，同时比油耗降低了5.63%。

By utilizing electromagnetic valve, we can control opening and closing timings of intake and exhaust valves according to the operating situation of the engine. Therefore, the engine performance can be improved suitably in exhaut emission during starting, idle stability, fuel comsumption and engine power, etc. When an engine rotates in the low speed, gas flow is bad and the throttle which adjusts air mass is apt to cause the pumping lose of the engine.

中文摘要传统机械式可变汽门正时系统为分段固定式机构，无法根据引擎转速以及负载变化来提供适当的汽门正时；利用电磁式气阀可根据引擎当时状况控制进排气门的开启与关闭正时以及汽门持续开启正时，因此引擎在冷启动废气排放、怠速稳定性、燃油消耗率以及引擎性能等方面均相当之改善。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.

Lugalbanda 是神和被崇拜了一千年多 Uruk古埃及喜克索王朝国王。

I am coming just now,' and went on perfuming himself with Hunut, then he came and sat.

我来只是现在，'歼灭战perfuming自己与胡努特，那麼，他来到和SAT 。
