There are two main types of engine designs: OHV and OHC. OHV engines have an overhead valve (OHV), while OHC engines have an overhead camshaft (OHC). Both designs have their pros and cons, but which one is better? In this blog post, we’ll explore the differences between OHV and OHC engines and see which one comes out on top. Stay tuned!
What is OHV?
OHV, or overhead valve, is a type of internal combustion engine in which the valves are actuated by pushrods from a camshaft located in the engine block above the cylinders. OHV engines have been used in a wide variety of vehicles, from cars to motorcycles to lawnmowers. OHV technology is typically more efficient than older pushrod designs, and it allows for a higher compression ratio, which can result in increased power.
OHV engines are also generally more compact than other types of engines, making them ideal for use in small vehicles. While OHV engines are not without their drawbacks – they can be noisy and difficult to service – they remain a popular choice for many manufacturers.
What is OHC?
OHC, or overhead camshaft, is a type of engine design in which the camshaft is located above the pistons in the cylinder head. OHC engines are more efficient than traditional pushrod designs because they allow for better airflow through the engine and require fewer moving parts.
OHC engines are also typically lighter and more compact than pushrod designs, making them ideal for use in high-performance vehicles. OHC designs can be found in a variety of engines, including inline-four, V6, and V8 configurations. OHC engines are also typically more expensive to manufacture than pushrod designs, due to the complexity of the cylinder head.
Differences between OHV and OHC
OHV engines have their valves actuated by pushrods and rockers from a camshaft located in the engine block, while OHC engines have the camshaft located in the cylinder head and the valves are actuated by the camshaft directly or by followers and pushrods.
- OHV engines are less complex and therefore cheaper to manufacture, but they are also heavier and tend to vibrate more. OHC engines are more efficient and powerful, but also more expensive to produce.
- OHV engines are typically found in older vehicles, while OHC engines are more common in newer models. OHV engines may be easier to maintain, but OHC engines tend to require less overall maintenance.
- When choosing between OHV and OHC, it is important to consider the cost, power, efficiency, and maintenance requirements of each option.
Conclusion
The choice between OHV overhead valve and OHC overhead camshaft can be difficult for engine builders. Each has its own benefits that should be considered when making a decision. In the end, it is important to choose the right option for your specific build and driving needs.
