What is a DOHC engine

[McElizabeth]

DOHC stands for Double Overhead Camshaft engine. Relevant information is as follows: 1. Advantages of DOHC: DOHC engines generally have greater torque and higher power compared to regular engines. This results in approximately 15% more horsepower output than conventional engines. Additionally, the pistons in DOHC engines are different from those in regular engines, as they require stronger pistons to maintain normal engine operation. 2. Principle of DOHC: DOHC engines utilize two camshafts. From the working principle of engines, it can be understood that to complete a working cycle, the processes are intake, compression, combustion, and exhaust. The cylinders need intake and exhaust valves for air intake and exhaust, and the role of the camshaft is to mechanically coordinate the opening and closing actions of these valves.
