An overhead camshaft (OHC) engine is a piston engine in which the camshaft is located in the cylinder head above the combustion chamber.[1][2] This contrasts with earlier overhead valve engines (OHV), where the camshaft is located below the combustion chamber in the engine block.[3]
Single overhead camshaft (SOHC) engines have one camshaft per bank of cylinders. Dual overhead camshaft (DOHC, also known as "twin-cam"[4]) engines have two camshafts per bank. The first production car to use a DOHC engine was built in 1910. Use of DOHC engines slowly increased from the 1940s, leading to many automobiles by the early 2000s using DOHC engines.
