Editing Ford CVH engine (section)

==Hybrid engines==
=== Schrick 16V ===
In 1982 the German company ''Dr. Schrick GmbH'', later renamed ''AVL Schrick'', developed a [[Overhead camshaft engine#Double overhead camshaft (DOHC)|double overhead camshaft]] (DOHC) [[multi-valve]] cylinder head for the 1.6&nbsp;L CVH block.<ref name="ff-jan2014"/><ref name="cf-jul2020"/> Each of the two overhead camshafts is installed in a separate camshaft carrier that is attached to the main body of the cylinder head. Each carrier has its own cam cover. Fitted with an original RS1600i engine intake manifold, a tubular exhaust manifold, and modified ignition, prototype engines developed {{cvt|99|kW|hp|0}}.

In contrast to cylinder head conversions produced for Ford by [[Cosworth]], the Schrick cylinder head never went into series production. With the introduction of the multi-valve Zetec engine, Schrick stopped development.

=== ZVH/ZE-VH ===
The ZVH or ZE-VH engine mounts a CVH 8 valve cylinder head on a Zeta/Zetec engine block.<ref name="jh-zvh"/> This is possible because the cylinder bore spacing, locations of the water and oil passages, and the cylinder head bolts on these engines are identical. 

This combination of parts allowed the owner of a CVH-powered car to retain the cylinder head and associated parts from the original engine while substituting a stronger, large displacement engine block. Some builders have built ZVH engines that used the cylinder head, fuel injection system, ignition system, exhaust manifold, and turbocharger from the Escort RS combined with a Zetec block.

The engine's name indicates a '''Z'''etec/C'''VH''' hybrid.
