What does DOHC stand for?

[AnnaLynn]

It is a type of automobile engine. A DOHC engine has greater torque and power compared to a conventional engine. Relevant details are as follows: 1. Dual Overhead Camshaft: As the name suggests, DOHC stands for Dual Overhead Camshaft. From the working principle of an engine, it is understood that to complete a working cycle, the processes are intake, compression, combustion, and exhaust. The cylinder requires intake and exhaust valves to perform these functions. The role of the camshaft is to mechanically coordinate the opening and closing actions of these valves. SOHC (Single Overhead Camshaft) means that both the intake and exhaust valves are operated by a single camshaft, while DOHC uses two separate camshafts to independently control the intake and exhaust valves. 2. Advantages: The benefit of DOHC is that it allows for easy adjustment of the timing for opening and closing the intake and exhaust valves. This enables the engine to deliver ample torque at low speeds and maximum horsepower output at high speeds. Generally, high-capacity, high-speed engines often adopt DOHC. DOHC does not increase fuel consumption; instead, it allows the engine to perform more efficiently.
