气门

Chinese ten-day mill sword, the Company's products tightly around the connecting rod boring machine-watt, valve seats boring machine, cylinder body bushing boring machine, cylinder head cylinder block grinding milling planar four types of continuous improvement, refinement and extension.

天华人十年磨一剑，公司产品紧紧围绕连杆瓦镗床、气门座镗床、缸体轴瓦镗床、缸体缸盖平面磨铣床这四种类型不断改进、完善和延伸。

Next, in order to ensure the process precision and production efficiency of boring machine tool ,the jig uses 'one surface-two sell' .the way of Clamps is hydraulic pressure clamping, which replaced by Manual clamping.

其次，夹具采用一面两销定位，保证了导管孔及气门阀座孔对定位销孔的位置精度。

目前，本公司有以下多个摩托车系列：链轮、链条、制动蹄、离合器压盘点火器、整流器、继电器、高压包、磁电机线圈、皮带、减震器、压条、气门、导管、凸轮轴、时规链、火花塞、摇臂、活塞、活塞环、启动盘、轴承、油箱盖、套锁、转向轴承、油量计、滤清器喇叭、驱动盘、从动轮总成、缓冲胶、中轴套、启动电机、辐条、开关按纽等。

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。

In consideration of the nonlinear characters of driving chain, with the general perturbation method, the asympototical solution to the nonlinear dynamic equation of the valve train with multinomial timing cam of symmetrical type is reached in this paper.

本文在考虑到传动键的非线性特性情况下，用普通小参数法求出了具有对称多项式凸轮的配气机构气门的渐近解。

The main series products cover three aspects such as driven gears of motorbikes, electronikc power dual pinion wheels, automobile chain wheels, pulley wheels, valve guide, seat bush, signal wheels, disc, and bearing covers, electrical rear driven bridge powder metallurgical wheel and speed different gears. The parts also cover series for clutch plates for trains and automobiles air conditioning compressors as well.

产品系列包括：摩托车从动齿轮、电起动双联齿轮系列；汽车发动机链轮、皮带轮及气门导管、座圈、信号轮、相位盘、轴承盖系列；电动车后驱动桥粉末冶金大齿轮及差速伞齿轮系列；火车、汽车用离合器面片、空调压缩机粉末冶金零件系列。

Our company is a modern one whose specially is to fabricate series products for automobile, such as ROCKER ARM, ROCKER SHAFT, CLUTCH LEVER, CLUTCH FORK, KING PIN KIT and etc.

我公司专业制造汽车发动机气门摇臂、摇臂轴、离合器分离杆、离合器拨叉、转向节主销等系列产品的现代化企业。

The spring is under compression, which means it tries to expend and thereby tries to keep the valve seated.

弹簧被压缩时，意味着弹簧要努力伸张，从而努力保持气门的落座状态。

With engine lock-pinned at "TDC" of No. 1 piston's compression stroke, check and adjust valve clearance on Nos. 1, 3 and 5 exhaust valves and Nos. 1, 2 and 4 intake valves.

使引擎销锁在1号活塞压缩冲程的&TDC&位置，检查并视需要调节1、3、5排气阀和1、2、4进气阀的气门间隙。

During the compression stroke, the crankshaft continues to rotate, the piston is forced upward in the cylinder, and both intake and exhaust valves are closed.

在压缩冲程，曲轴继续旋转，活塞向上被迫在汽缸内，都进排气门关闭。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
