气门

Kinematic and dynamic calculations are carried out, and the features of intake and outtake valve train are got. Especially, the area of fullness ratio of the valve lift curve, cam to tappet contact stress, lubrication coefficient and the features of valve seating are analyzed.

在此基础上分析了配气机构进排气部分的工作特性，着重从气门升程曲线的丰满系数、凸轮与平面挺柱间接触应力，凸轮与平面挺柱间润滑效果以及气门落座特性等方面进行了分析。

MWM engine add an exhaust port at a four-stroke engine cylinder wall, and it be controlled to opening or close by a valve, this structure can make the engine has different working mode by different valve working together.

MWM发动机在普通四冲程发动机的气缸侧壁增加了一个排气口，且由气门控制其开闭，通过处于不同位置气门的配合工作，从而实现其各种工作模式和工作过程。

First of all, the principle of the traditional throttle pedal is driven by cable-driven throttle to control engine power output, the current most advanced vehicles have been imported electronic throttle, its principle is based on servo motor control section of valve switching point of view, but the two operators who encounter the accelerator pedal stuck failure, life-saving methods should be the same, unless the electronic throttle with automatic reset power design, special or adapted vehicles is another matter.

首先，传统油门的原理是藉由脚踏板拉动钢索驱动节气门，藉以控制引擎动力输出，目前的高级车种大多已导入电子式节气门，其原理是以伺服马达控制节汽门开关角度，但两者如遭遇油门踏板卡死失效，救命的方法应该是一样的，除非电子式节气门有断电自动复位设计，特殊或改装车种则另当别论。

This Analyzing System enables analysis of various factors affecting valve and valve seat wear.

本试验台用于分析影响气门，气门阀座磨损的各种因素。

Valve for the hydraulic rod to mention, the automatic adjustment of valve clearance.

The particle valve model,obstacle cell valve model as well as the body-fitted valve model representing the valve motion were established.Furthermore,a modified equation about the particle valve model was put forward.

建立了反映气门运动的粒子阻滞模型、障碍物单元模型以及贴体气门模型，并提出计算粒子阻滞的修正公式。

The master and slave pistons may be selectively actuated and the bleed hole may be selectively blocked and unblocked to provide partial bleeder braking as a result of the valve actuation motion imparted from the cam to the valve bridge through the rocker arm.

主活塞和从动活塞可选择地致动并且排放孔可选择地阻塞和打开从而提供部分排放制动，因此气门致动运动通过摇臂从凸轮传递给气门桥。

A variable valve gear and a method of adjusting valve opening rates capable of accurately controlling the rate of air and the intensity of swirl flow in cylinders.

本发明涉及一种可变气门操作装置和一种气门打开量调节方法，并且能够精确地控制缸内空气的量和旋涡流的强度。

So the author do a lot of research and study on the automatic system of making tire valve and has made out a automatic system for assembling tire valve.

鉴于此，作者从以下几个方面对全自动气门芯装配系统作了深入的研究，开发出了一台全自动气门芯装配系统。
