An Overhead Valve (OHV) is a type of engine design where the valves are located in the cylinder head, above the combustion chamber. This configuration allows for more efficient airflow into and out of the engine, improving performance and fuel efficiency. OHV engines typically use pushrods to operate the valves, which can simplify the design and reduce weight compared to other systems. The OHV design is commonly found in many types of vehicles, including cars and motorcycles. It is often associated with internal combustion engines and is favored for its balance of power and efficiency. This design contrasts with other valve arrangements, such as Overhead Cam (OHC) engines, which have a different mechanism for valve operation.
