 Which is the Best Engine Valvetrain Design? OHV, SOHC, DOHC or Flathead | Pros and Cons

Valvetrain:

The valvetrain is a mechanical system in an internal combustion engine that manages the opening and closing of the intake and exhaust valves. Its purpose is to regulate the timing of these valve operations to allow the intake of air/fuel mixture into the combustion chamber and the expulsion of exhaust gases.

The intake valves are responsible for controlling the flow of the air/fuel mixture into the combustion chamber during the intake stroke. On the other hand, the exhaust valves regulate the flow of spent exhaust gases out of the combustion chamber during the exhaust stroke. By coordinating the timing of valve openings and closings, the valvetrain ensures efficient combustion and optimal engine performance.

Types of valve train

Different engines may utilize variations in valvetrain designs, such as an overhead valve (OHV), overhead camshaft (OHC), or dual overhead camshaft (DOHC) configurations.

Advanced technologies like variable valve timing (VVT) and variable valve lift (VVL) allow for even greater control over valve operation, optimizing engine performance across various operating conditions.
