What is the Difference Between Single Overhead Camshaft and Dual Overhead Camshaft?

[EllaRose]

The differences between single overhead camshaft and dual overhead camshaft: 1. A single overhead camshaft is arranged with one camshaft in a cylinder head, while a dual overhead camshaft is arranged with two camshafts in a cylinder head. 2. A single overhead camshaft drives the intake and exhaust valves to open and close through rocker arms, whereas a dual overhead camshaft has one camshaft controlling the intake valves and another controlling the exhaust valves. Below is an introduction to automotive camshafts: The camshaft is a component in piston engines. Due to its high rotational speed and the need to withstand significant torque, the design requires high strength and support for the camshaft. Its material is typically high-quality alloy steel or alloy steel.
