Oct 25, 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.

The difference between an OHV and OHC engine is all about the configuration of the cylinder heads. OHV stands for overhead valve, whereas OHC means overhead cam. An OHV engine has a camshaft placed between the engine's cylinder heads, also known as "cam-in-block."

Oct 4, 2024 · Pushrod engines, also known as overhead valve (OHV) engines, employ a different valvetrain structure compared to overhead cam (OHC) engines. In OHC engines, the camshafts sit directly above the valves, which can be single cam (SOHC) or double cam (DOHC), governing intake and exhaust without intermediary components.

Oct 3, 2024 · Engines primarily come in three configurations: OHV (Over Head Valve), SOHC (Single Over Head Camshaft), and DOHC (Double Over Head Camshaft). Each design has its implications on how an engine delivers power, as well as its complexity and cost of manufacturing.

Jul 24, 2024 · There are several types of valvetrains, but one common design is the OHV or overhead valve. Overhead valve configurations offer some advantages over other designs, such as making great low-end...

Oct 4, 2024 · OHV stands for Over Head Valve, a term synonymous with pushrod engines where the camshaft resides in the engine block. This configuration is an older yet enduring legacy of internal combustion engine design.

As the name implies, OverHead Valve engines (OHV) have the valves located above the combustion chamber, in the roof of the cylinder head. The OverHead Valve layout permits smoother fuel mixture intake, plus quicker and more complete exhaust. This increased combustion efficiency, in turn, enables a higher compression ratio to be used.

As the name implies, Overhead Valve engines (OHV) have the valves located above the combustion chamber, in the cylinder head. The OHV layout permits smoother fuel mixture intake, quicker and more complete exhaust. The increased combustion efficiency enables a higher compression ratio to be used.

Jan 3, 2025 · An OHV, or Overhead Valve, lawn mower engine is a type of small gasoline engine where the valves are located in the cylinder head, above the piston. This design is in contrast to side-valve engines, where the valves are located in the engine block, alongside the piston.

Mar 12, 2025 · Single-cylinder OHV engines are the most common type of engine found in residential lawn mowers. They are lightweight, compact, and provide enough power for most standard lawn care tasks. These engines typically range from 4 to 7 horsepower.
