An overhead valve engine, abbreviated (OHV) and sometimes called a pushrod engine, is a piston engine whose valves are located in the cylinder head above the combustion chamber. This contrasts with flathead (or "sidevalve") engines, where the valves were located below the combustion chamber in the engine block.
24 kwi 2023 · An overhead valve engine is a type of internal combustion engine in which the valves are positioned above the combustion chamber. It uses a system of pushrods, rocker arms, and lifters to operate the valves, which are usually located in the engine block, directly above the combustion chamber.
25 paź 2019 · OHV means Over Head Valve. Although almost all modern car engines have valves placed in the cylinder head, the term OHV is used to describe a pushrod engine, with the camshaft placed in the cylinder block. OHC stands for Over Head Cam, or the camshaft is installed in the cylinder head.
Overhead valve engines revolutionized the automotive industry by positioning valves in the cylinder head, leading to improvements in power, fuel efficiency, and overall performance. The main components of overhead valve engines include the camshaft, pushrods, rocker arms, and valves, which work together to regulate the flow of air, fuel, and ...
