OHC Over Head Camshaft

The mathematical model about the characteristic of high order polynomial dynamic cam for the overhead camshaft of high-speed gasoline engine is built and the computing formulas of correlative coefficients are given.

针对高速汽油机顶置凸轮轴的设计,建立了高次方多项式描述动力凸轮特性的数学模型,并给出了相关系数的计算公式,最后根据数学模型对一台汽油机的凸轮型线进行了优化。

The focus is on the definition, status quo of research and application of valve train in the overhead camshaft.

本文论述了高速柴油机中配气机构优化设计方法的概念、种类、研究内容及其应用，重点阐述了顶置凸轮轴式配气机构的定义、研究现状与应用。

Owing to the fact that the rocker arm ratio of OHC valve train was variable,three measures were adopted for raising the calculation precision.

由于顶置凸轮轴式配气机构的摇臂比是变化的,为提高计算精度,采取了3项措施:根据凸轮升程数据求取气门理论升程数据并对该数据进行曲线拟合;将从动件的升程曲线分为缓冲段和工作段分别进行曲线拟合;将最优化计算和最小二乘法相结合对工作段进行曲线拟合。

As the camshaft continues to rotate, the high spot moves way from the valve mechanism.

因为凸轮轴继续旋转，凸轮轴上的凸起部分离开气门装置。

As the lobe of the cam comes up under the cam follower, it pushes the cam follower upward (away from the camshaft).

当凸轮的凸角在凸轮挺杆下出现时，它推动凸轮挺杆向上运动(离开凸轮轴)。

The value-opening mechanism includes a valve lifter and a cam on a camshaft.

一套气门开启机构包括一个气门挺杆和一个在凸轮轴上的凸轮。

But a camshaft driven directly by the crankshaft gear turns in the opposite direction.

但是凸轮轴被曲轴齿轮直接驱动，其将在相反方向上转动。

Two TDC (Top Dead Center) sensors are mounted at the rear of the single camshaft.

两个上死点的传感器安装在凸轮轴的后面。

In addition, when the camshaft is located over the cylinder head, the arrangement is known as an overhead camshaft( OHC) design.

另外，当凸轮轴位于汽缸盖上面时，这种方式被称为是顶置凸轮轴(HC)构。
