2019年3月24日 · If the engine has a single camshaft it’s called a SOHC (Single Overhead Camshaft) engine and if the engine has two camshafts it's called DOHC (Double Overhead Camshaft) engine. Every engine, whether it’s air-cooled or liquid-cooled, needs camshafts, whose main purpose is to open the intake and exhaust valves.

2020年1月23日 · SOHC stands for “single overhead camshaft” while DOHC represents “double overhead camshaft.” As the names suggest, an SOHC engine is served by a single camshaft which carries the intake and exhaust cam lobes. A DOHC engine, on the other hand, has one camshaft dedicated to intake and one for exhaust.

2025年2月18日 · A DOHC, four valves per cylinder configuration allows better airflow at high engine speeds, resulting in better top end power. DOHC engines also allow the spark plug to be placed right in the middle of the combustion chamber which in turn promotes efficient combustion.

2025年2月17日 · DOHC is the acronym for “Dual Overhead Camshaft”. One may call it a “dual overhead cam”, “double overhead cam”, or “twin-cam” engine. In this type of engine, above each bank of the cylinder head, there are 2 camshafts.

2018年9月25日 · DOHC stands for “double overhead cam,” while SOHC stands for “single overhead cam.” The most obvious difference between the two engines is the number of cams. On the older single-overhead-cam...

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. Additionally, this design does not restrict the airflow.

2024年2月17日 · The DOHC engine is implemented with 4 valves by default which leads to intake and exhaust air on a large scale. DOHC setup enhances airflow to produce more power than the SOHC engine, as DOHC can implement more valves so it can complete more cycles at a time and produce higher RPMs.

When comparing SOHC vs DOHC, a bike with an SOHC engine is more affordable and requires less maintenance. Moreover, it is easy to repair in case of a failure, lighter in weight, and higher initial torque than DOHC.

2015年8月20日 · Most engines with the DOHC setup are known to rev higher than their equivalent SOHC designs. This also allows a much more optimized valve setup, thus improving performance. DOHC engines have lesser torque just off the line due to their bulk but higher up the rev ranges, this becomes an advantage as they have greater peak torque as well as ...

A Double Overhead Camshaft (DOHC) engine uses two camshafts—one for intake valves and the other for exhaust valves. This separation allows more precise control over valve timing, resulting in better performance and fuel efficiency. Many high-performance DOHC engine bikes in India utilize this setup for improved power and speed.
