The letters CVH denote a particular type of 4-cylinder internal combustion engine produced by the Ford Motor Company in the 1980s.

The CVH (Compound Valve angle Hemispherical combustion chamber) engine was introduced by Ford in 1980 in the third generation Ford Escort. It was later used in the Ford Sierra as well as the second generation Ford Fiesta. The engine was originally conceived in 1974 and is unique in terms of its valves mounted at a compound angle, which allows for a hemispherical combustion chamber shape without using a more expensive twin camshaft arrangement. It also featured hydraulic valve lifters, a first for a Ford engine.

Throughout its 20-year production life, the CVH had a reputation for being harsh and noisy at high speeds, and for its lubricating oil to sludge prematurely. A redesign in 1995 saw it being renamed CVH-PTE, with a thicker crankcase to combat the harshness at high revs, although the 1990's saw it gradually being phased out in favour of the newer Zetec 16-valve unit.
