Single overhead camshaft (SOHC) engines have one camshaft per bank of cylinders. Dual overhead camshaft (DOHC, also known as "twin-cam" [4]) engines have two camshafts per bank. The first production car to use a DOHC engine was built in 1910.

DOHC is an acronym that refers to Double Overhead Camshaft or Double overhead camshaft. A type of motors in which two camshafts are located in the cylinder heads, to directly move the valves. Actually, are part of OHC engines.

2023年11月5日 · DOHC stands for Dual Overhead Camshaft, which means your car has two camshafts on top of the cylinders. One is for engaging the intake valves, the other is for exhaust valves. In contrast, SOHC (Single Overhead Camshaft) engines only have one camshaft responsible for both the intake and exhaust valves.

DOHC是英文Double Overhead Camshaft的缩写，中文含义是“双顶置凸轮轴”；SOHC是英文Single Overhead Camshaft的缩写，中文含义是“单顶置凸轮轴”。 现在的轿车发动机，基本上都采用DOHC(双顶置凸轮轴)的布置形式了，采用SOHC(单顶置凸轮轴)的车型越来越少。

SOHC (Single Overhead Camshaft)的中文含义是“单顶置凸轮轴”，DOHC (Double Overhead Camshaft)的中文含义则是“双顶置凸轮轴”。 它们是发动机配气机构中凸轮轴的不同布置形式。 那么发动机为什么要这样设计呢？ 这要从发动机配气机构说起。 （呵呵，有点要长篇大论的感觉）。 发动机配气机构的功用就是按照发动机工作循环和点火次序的要求，定时开闭进、排气门，向气缸供给新鲜的可燃混合气（汽油机）或空气（柴油机），并及时排出废气。 上图是一个比 …
