4-cylinder engines 1.6l kent/1.6l/1.9l cvh/2.0l/2.3l ohc/2.3l/2.5l hsc 1.6l kent engine this is a proven overhead valve design the combustion face of the head is virtually flat most of the combustion chamber is in a dished piston camshafts are mechanical with solid tappets parts for this engine are identified as 1.6l kent you ll find it under the hood of many ford models including pinto capri fiesta and the english-built cortina a gt performance version is the basis for an amateur class of racing formula ford only production-type parts are normally legal in formula competition check with your racing association for the latest rules 1.6l cvh and 1.9l cvh engines the 1.6l cvh engine was introduced in 1981 for the escort lynx exp and ln7 car line parts for this engine are identified as 1.6l cvh it has a canted valve head cvh with the valve angles to match the hemispherical combustion chambers reliefs are cut into its domed pistons to match valve and combustion chamber configuration a hydraulic camshaft is used in production a performance version was introduced in 1984 with electronic fuel injection and a turbocharger a 1.9l cvh was introduced on 19851/2 models it has a 4.250 mm higher deck height to achieve a longer stroke some 1.6l/1.9l cvh parts are interchangeable 1.6l/1.9lcvh 2.3lohcturbo-intercooled 1.6l/1.8l/2.0l dohc engine ford currently offers four double overhead cam dohc 4-cylinder engines the 1.6l dohc was introduced on 1991 capri the 1.8l dohc on 1991 escort gt/tracer lts a 2.0l dohc on 1993 probe and a second 2.0l dohc design on the 1995 contour/mystique these engines feature four valves per cylinder and a centrally located spark plug in a pentroof combustion chamber for efficient air flow and combustion ford racing parts have not been developed for these production double overhead cam engines 2.3l/2.5lhsc 2.0lohc 2.0l/2.3l/2.3l ohc engines design-wise these metric engines are very similar and have a belt-driven overhead camshaft dimensionally however they are very different in terms of bore stroke bore spacing block deck height and crankshaft journal diameters the european eao 2.0l was produced in 1971-74 cars the 2.3l ohc is widely found on 1974-95 models including a high-tech version that powered the thunderbird/cougar turbo coupe a two spark plug per cylinder design with distributorless ignition was introduced on 1989 ranger and 1991 mustang models parts for these engines are identified as 2.0l eao and 2.3l ohc respectively in 1983 a 2.0l version of the 2.3l ohc engine was introduced on ranger and aerostar trucks the only basic difference is in bore diameter as shown in the chart on page 200 thus most parts interchange parts shown for the 2.3l ohc can be used in the 2.0l truck engine except those relating to bore diameter pistons etc in 1998 the ranger engine grows to 2.5l with increased stroke with dual squish areas and centrally located spark plug for fast burn combustion parts are not interchangeable with other 4-cylinder engines ford racing parts have not yet been developed for the 2.2l engine 2.3l/2.5l hsc engines the 2.3l hsc was introduced in 1984 tempo/topaz models except for displacement it bears no resemblance to the 2.3l ohc the 2.3l hsc is a conventional cam-in-block in-line design much like a 6-cylinder with two bores chopped off hsc refers to its swirl combustion chamber that s achieved by shrouding the valves and other minor head work in 1986 a larger displacement 8mm longer stroke 2.5l hsc was introduced with electronic fuel injection 2.2l probe engine ford introduced a new fuel injected 2.2l engine in naturally aspirated and turbo versions for 1989 probe models it s an overhead camshaft design with shaft-mounted rocker arms and three valves per cylinder 2 intake 1 exhaust the cylinder head is cast from aluminum and features dome-shaped combustion chambers 222 techline 800 ford788
