In automotive engineering, an Overhead Valve or OHV piston engine is one with pushrod-actuated poppet valves perpendicular to the pistons. This contrasts with previous designs, including side valves and sleeve valves.
Today, the technology is widespread, and the term, "OHV", is generally used to differentiate a pushrod engine from one which uses overhead cams, although both types employ overhead valves.
