dualoverheadcam
A dual overhead camshaft (DOHC) engine is a type of internal combustion engine that features two camshafts positioned directly above the cylinder head. This arrangement contrasts with older single overhead camshaft (SOHC) designs, which have only one camshaft. In a DOHC engine, each camshaft typically operates a set of valves for each cylinder. One camshaft is usually responsible for the intake valves, while the other handles the exhaust valves. This separation allows for more precise control over valve timing, which can improve engine performance and efficiency.
The DOHC configuration offers several advantages. By having dedicated camshafts for intake and exhaust, engineers can
Another benefit of DOHC is the potential for simpler valvetrain design for certain configurations, such as
