FORD 1.9 CVH

The CVH (Compound Valve angle Hemispherical combustion chamber) engine was introduced by Ford in 1980 in the third generation European Ford Escort and for the 1981 North American Escort. It was later used in the Ford Sierra as well as the second generation Ford Fiesta and from 1983 it was used in the Ford Orion. Engines were built in the Dearborn Engine Plant for the North American market, and in Ford's then-new engine plant in Bridgend in Wales for the European market. The engine was originally conceived in 1974 and had a single overhead cam. Its valves were mounted at a compound angle in hemispherical combustion chambers, although some versions altered the combustion chamber shape to increase swirl. It also featured hydraulic valve lifters, a first for a European Ford engine. The engine was given different names throughout its production. From 1991 to 1996 in the Ford Escort, it was "1.9L SEFI"; and from 1997 to 2002, it was "Split Port Induction 2000". From 2000 to 2004 in the Ford Focus, it was "Split Port".[1] Despite its considerable shortcomings in terms of Noise, vibration, and harshness (NVH) and its intolerance of poor or neglected servicing, the CVH was regarded as being a very easy engine to tune, with many of its key components being considerably over-engineered. It wasn't long before the engine started receiving attention from the aftermarket tuning industry, and the 1.6 L version quickly became a stalwart of the tuning scene in the 1980s and 1990s with some significant increases in power output (over 200 bhp (150 kW)) being extracted from the turbocharged variants. The naturally aspirated 1.6 L was a popular choice for the kit car industry, where it could be relatively easily and cheaply tweaked to around 130 bhp (97 kW). The CVH was produced in many different capacities from 1.1 to 2.0 L, the smaller versions being exclusively for the European market. The CVH was enlarged to 1.9 L for the North American 1986 model year Escort. Bore was now 82 mm (3.2 in) and stroke was 88 mm (3.5 in). This stroke length was later used in the 2.0 L CVH engines, and continued into the Zeta engine which replaced it. This long stroke necessitated a raised engine block deck, a design also shared with later units. The camshaft and water pump are driven by the timing belt. This engine is of a non-interference design: the valves don't contact the pistons if the timing belt breaks. Output was 86 hp (64 kW) and 100 ft·lbf (140 N·m) with a carburetor; when electronic throttle-body fuel injection (CFI, or Central Fuel Injection) was added, the basic 1.9 L added 4 hp (3.0 kW), although torque was little changed. Multi-port fuel injection and hemispherical "hemi" combustion chambers were added for the 1986 Escort GT's EFI HO engine, increasing output to 108 hp (81 kW) and 114 ft·lbf (155 N·m). This engine developed a good reputation for performance and surviving GTs of this generation are quite fun to drive. The 90 hp (67 kW) 1.9 L CFI engine of the late 1980s, particularly when equipped with either the four- or five-speed manual transaxle, was notable for delivering outstanding fuel economy. Somewhat surprisingly, four-speed Escort Pony models achieved better mileage than five-speed cars, with upwards of 30 mpg in city driving and 40–45 mpg on the highway not uncommon. The second generation of American Escort utilized sequential EFI for 1991–1996, but power and torque were little changed at 88 hp (66 kW) and 108 ft·lbf (146 N·m) respectively.[WIKI]
