The engine's name is an acronym for either Compound Valve-angle Hemispherical or Canted Valve Hemispherical, where "Hemispherical" describes the shape of the combustion chamber. [1] [2] The CVH was introduced in 1980 in the third generation European Escort and in 1981 in the first generation North American Escort.
A hemispherical head ("hemi-head") gives an efficient combustion chamber with minimal heat loss to the head, and allows for two large valves.However, a hemi-head usually allows no more than two valves per cylinder due to the difficulty in arranging the valve gear for four valves at diverging angles, and these large valves are necessarily heavier than those in a multi-valve engine of similar ...

Rudd reduced the deck height by 0.04 in (1.0 mm) to raise the compression ratio to 10.5:1, increased the diameter of the inlet valves to 1.565 in (39.8 mm), modified the inlet runners' shape for the larger valves and installed Super Special Equipment D-type camshafts.
1 ‐ Induction 2 ‐ Compression 3 ‐ Power 4 ‐ Exhaust. The top dead center (TDC) of a piston is the position where it is nearest to the valves; bottom dead center (BDC) is the opposite position where it is furthest from them. A stroke is the movement of a piston from TDC to BDC or vice versa, together with the associated process.
