How Do You Spell OVERHEAD VALVE?

1. Overhead valve (OHV) refers to a type of internal combustion engine design where the valves are located within the cylinder head, directly above the combustion chamber. Also known as pushrod or valvetrain system, OHV engines have the valves mounted above the combustion chamber, making use of a camshaft and pushrods to open and close the valves.

   The design of overhead valve engines allows for precise control over the combustion process by optimizing the timing and duration of the intake and exhaust valve openings. This precision helps improve fuel efficiency and power output. Additionally, OHV engines often provide better low-end torque due to the optimal placement of the valves.

   Compared to other valve configurations, such as overhead camshaft (OHC) engines, the OHV design is often simpler and less expensive to manufacture and maintain. It generally offers better durability and reliability due to the reduced number of moving parts and their positioning. Also, the relatively compact size of OHV engines makes them well-suited for a range of applications including cars, motorcycles, and small engines like lawnmowers.

   In summary, an overhead valve (OHV) engine is a type of internal combustion engine where the valves are located within the cylinder head, directly above the combustion chamber. This configuration offers several advantages including precise control over the combustion process, improved fuel efficiency, power output, low-end torque, durability, and relatively simple and cost-effective construction.

Common Misspellings for OVERHEAD VALVE

The word "overhead valve" is derived from the combination of two separate terms: "overhead" and "valve".

The term "overhead" refers to something located above or higher than the regular position. In the context of engines, it specifies that the valves are placed above the combustion chamber, rather than being positioned within the cylinder block.

The term "valve" refers to a device that controls the flow of fluids or gases by opening or closing passages. In the case of combustion engines, the valves regulate the intake of fuel-air mixture and the exhaust of combustion products.

By combining these terms, "overhead valve" describes an engine design that places the valves on the top of the combustion chamber, typically in the cylinder head, above the piston. This configuration enables more efficient intake and exhaust processes, leading to better performance and power output in comparison to a side-valve or flathead engine design.

Plural form of OVERHEAD VALVE is OVERHEAD VALVES
