2020年7月27日 · 所谓的“DOHC、SOHC”是指凸轮轴的在发动机中的布置方式。 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”。

2023年3月9日 · SOHC stands for a single overhead camshaft engine. DOHC stands for dual overhead camshaft, which means that there are two camshafts in the cylinder head. Most modern motors fit into one of these categories. There’s more to evaluate aside from how many camshafts are in each cylinder head.

2025年2月18日 · When a single camshaft governs both intake and exhaust valves, the setup is commonly known as SOHC. On the other hand, in a DOHC setup, there are two dedicated camshafts, one to push the inlet valves and the other to push the ones which let the gases escape from the cylinder after combustion.

2019年10月25日 · Although almost all modern car engines have valves placed in the cylinder head, the term OHV is used to describe a pushrod engine, with the camshaft placed in the cylinder block. OHC stands for Over Head Cam, or the camshaft is installed in the cylinder head. SOHC means Single Overhead Cam, while DOHC means Double Overhead Cam. Which one …

2020年6月7日 · 通常DOHC有较强的高转速功率，在高速行驶时动力充足,但是其燃油经济性与低转速扭距与同排量的SOHC发动机相差太远。 虽然现在汽车的发动机大部分采用双顶置凸轮轴，但不代表单顶置凸轮轴就落伍了，单顶置凸轮轴还是有很多可圈可点的地方的。

2024年8月27日 · The main difference between SOHC and DOHC engines is the number of camshafts. SOHC (Single Overhead Camshaft) engines have one camshaft per cylinder bank, while DOHC (Dual Overhead Camshaft) engines have two camshafts per cylinder bank.

2021年5月4日 · A single overhead camshaft (SOHC) engine has just one camshaft located in the cylinder head. A dual (or double) overhead (DOHC) engine has two camshafts per cylinder head. SOHC engines are usually less complicated, easier to …

2025年1月11日 · A single overhead cam, or SOHC, has the camshaft at the top of the engine and is used for the functioning of both intake and exhaust valves. A double overhead cam, or DOHC, is two camshafts located at the top of the engine within the engine block and are used for the independent control of intake and exhaust valves. Single overhead cam (SOHC ...

2020年7月26日 · 所谓的“DOHC、SOHC”是指凸轮轴的在发动机中的布置方式。 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”。

2014年12月17日 · DOHC design allows a wider angle between intake and exhaust valves than SOHC design. Thus, it helps improve breathing and scavenging (removing exhaust gases) from the engine.
