ENGINE HISTORY FOUR-CYLINDER ENGINE SECTION 1.6L OHV “KENT” ENGINE Open-wheel racing enthusiasts associate this overhead valve design with the long-lived international Formula Ford series, the starting point for many professional drivers. Most of the combustion chamber is in a dished piston, where the mating cylinder head face is nearly flat. Production for European models (Cortina, Capri and Fiesta) is now phased out. Ford Racing sold numerous production-type parts for Formula Ford competition. 1.6L/1.8L/1.9L/2.0L SOHC “CVH” OR “SPI” ENGINES The two-valve CVH (Canted Valve Hemispherical) engine was introduced with the 1981 Escort and 1.6L/1.9L CVH 2.3L OHC (Turbo-Intercooled) later used in Focus. The layout is also called “Cam in head,” because it resembles a classic overhead valve geometry. A single overhead camshaft lifts up hydraulic lash adjustors, linking individually mounted rocker arms to valves “canted” at angles relative to the cam axis, as well as front to rear, to match the shallow hemispherical chamber. Manufactured at Dearborn (Mich.) Engine Plant, it was replaced by the Duratec® HE engine family. 1.6L/1.8L/2.0L DOHC MAZDA® ENGINES In the early 1990s, Mazda®-manufactured four-valve engines were shared with Ford applications. The 1.6L was introduced on 1991 2.3L/2.5L HSC 2.0L OHC Australian-made Mercury Capri (including a turbocharged variant), the 1.8L on 1991 Escort GT, and the 2.0L on the 1993 Probe. Ford Racing parts were not developed for this iron-block developed for the SOHC, including a partnership 178 horsepower in North American Fusion and architecture, which was replaced by the Zetec® with Esslinger® Engineering for an aluminum Escape applications. Ford Racing offers a and eventually Duratec® I-4 engine families. cylinder head.
