Ford CVH engine
Encyclopedia
The letters CVH denote a particular type of 4-cylinder internal combustion engine
produced by the Ford Motor Company
during the 1980s and 1990s.
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 has a single overhead cam. Its valves were mounted at a compound angle for 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.
Throughout its 20-year production life, the CVH had a reputation for being almost painfully coarse and noisy at high revs (CVH, said some pundits, was an acronym for Considerable Vibration and Harshness). Jeremy Clarkson
famously said of the CVH-powered Escort that "it was powered by engines so rough, even Moulinex
wouldn't use them".
The CVH was notorious for turning its lubricating oil to sludge
prematurely if the service schedule was skipped. Timing belts frequently failed about 60000–90000 mi (96,560.4–144,840.6 km).
The most common problem with the CVH is the tendency to drop a valve seat, which most often happens in the 2000-2004 Ford Focus sedan with the 2.0L CVH/SPI engine. These engines usually drop a valve seat with no warning, for no reason, even if the engine has been well maintained. With most dropped valve seat cases, a seat drops on the number 4 cylinder, with the next most common being the number 2 cylinder. With the factory valve seats, the typical life of the 2.0L SPI in a Focus is about 100-120k miles, but it can happen as early as 70k miles. When the valve seat drops out of the cylinder head, it falls into the cylinder and mashes up the piston
and cylinder head
. In some cases, the valve seat will exit the cylinder it dropped in and be sucked into other cylinders via the intake manifold until it's obliterated. A valve seat dropping into the cylinder can, and sometimes will, scar the cylinder wall up and bend the piston connecting rods
. When repairing an SPI with a dropped valve seat, it is very important to remove the intake manifold and have it thoroughly cleaned before bolting it up to a new cylinder head. If not cleaned, trapped particles in the manifold from the dropped valve seat will enter the repaired engine and scar the cylinder walls and sometimes ruin the new cylinder head. The best solution for avoiding the dropped valve seat problem is to purchase and install a new cylinder head that has had the valve seat problem fixed.
Despite its considerable shortcomings in terms of NVH
(Noise, Vibration and Harshness), and its aforementioned intolerance to poor or neglected servicing, the CVH was regarded as being a very easy engine to tune, and 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 phenomenal power outputs (over 200 bhp) 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.
The CVH was produced in many different capacities from 1.1 to 2.0 L, the smaller versions being exclusively for the European market.
In the united kingdom the 2 door mk 3 escort 1.3L with a 4 speed box was a popular choice for the teenagers who coudnt afford insurance on a 1.6L, or didnt like astras. The 1.3 escort had equal or better performance for the engine size plus it would do 0-60 using only 2 gears.
and Fiesta
from 1983 to 1986. Bore was 80 mm (3.1 in) and stroke was 64.5 mm (2.5 in). The 1.3 L was also planned for the North American version of the Escort, but engineering tests found it to be unacceptably underpowered, and plans to produce 1.3 L engines were scrapped just a few months before full-scale production.
For the facelifted "Mark 4", or "Erika-86" version of the European Escort in 1986, this engine was replaced by a 1.3 L version of the Kent/Valencia
engine in low series trim models—the higher series models used the newer 1.4 L CVH described below.
It was widely known as the 'Lean Burn' engine as it was designed primarily for fuel economy and featured a different cylinder head which was aimed less at power output than other CVH powerplants. The carburetted versions feature an unusual Weber 28/30 carb (replacing the unreliable Ford VV unit) with a manifold vacuum-actuated secondary choke (power valve), instead of the more usual sequential linkage which opens the secondary butterfly at 3/4 to full throttle. The idea was to save more fuel, especially with lead footed drivers, but the result was mainly a car which ran horribly lean under any kind of load, particularly after the famous CVH top-end wear begins to reduce engine vacuum with some mileage on the clock. The 1.4 L version is less tuneable than other CVH's, and some top-end parts are not interchangeable with the most common tuning parts; however replacing the carb with the common Weber 32/34 DMTL plus the appropriate inlet manifold makes them more driveable, albeit with a small increase in fuel consumption.
In South Africa, the 1.4 L CVH was fitted to the Ford Laser and Meteor, rebadged Mazda 323s. It replaced the 1.3 L Mazda E-series engine used in these cars and was itself replaced by the 1.3 L Mazda B-series engines.
), 90 hp KE-Jetronic catalyst mechanical fuel injection, 108 hp (EFI Electronic fuel injection with Ford EEC-IV engine management) as found in the XR3i or Orion GLSI or the 115 hp version offered only in the very rare Escort RS1600i – a car developed by Ford Motorsport Germany, the 1.6 CVH featuring reworked cylinder head, solid cam followers and bronze bearings for high revving applications and a host of other motorsport features.
. It made 132 hp at 6,000 rpm, and 133 ft·lbf (180.3 N·m) of torque at a very tractable 3,000 rpm. The boosted engine was substantially smoother than its normally aspirated cousins, the forced induction helping to damp out unpleasant harmonics. The block was slightly modified to provide an oil return from the turbocharger. Crankshaft and connecting rods were identical to the lesser 1.6 L models, but the Mahle pistons were unique to the RS Turbo. These are manufactured using a pressure cast method, which makes them considerably stronger and more expensive than the normal cast pistons. The pistons dropped the compression ratio to 8.3:1, allowing the use of large amounts of boost pressure. The standard engine only needs 7 psi of boost to produce its quoted power output, and is considered to be detuned from the factory. Because of its strength and detuned nature, tuners continue to increase the standard figures by more than 100% for a relatively reasonable fee. Even today, some 20 years after its release, new ways are being developed to extract even more performance.
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 and 100 ft·lbf (135.6 N·m) with a carburetor; when electronic throttle-body fuel injection was added, the basic 1.9 L added 4 hp, although torque was little changed.
Electronic fuel injection and hemispherical "hemi" combustion chambers were added for 1987's Escort GT, bumping output to 108 hp and 114 ft·lbf (154.6 N·m). This engine developed a good reputation for performance and surviving GTs of this generation are quite fun to drive.
The 90 hp 1.9 L 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 was little changed at 88 hp and 108 ft·lbf (146.4 N·m) respectively.
Note that the 1.1 L version used the 1117 cc Kent engine although some right hand drive examples were built with the CVH mechanicals in this capacity including the van variant.

1.4
The 1.4 L CVH replaced the 1.3 L CVH in the Escort, Orion and Fiesta from early 1986. Bore was 77.2 mm (3 in) and stroke was 74.3 mm (2.9 in). In European trim, this engine produced 75 bhp.It was widely known as the 'Lean Burn' engine as it was designed primarily for fuel economy and featured a different cylinder head which was aimed less at power output than other CVH powerplants.

The 1.6 L CVH was used in the 1980 European Escort and 1981 North American Escort. Bore was 80 mm (3.1 in) and stroke was 79.5 mm (3.1 in). Output was 69 hp and 86 ft·lbf (116.6 N·m), while European versions produced 90 hp in standard carburettor trim for vehicles with automatic transmission and 97 hp for the Fiesta XR2 and the Escort XR3 or Orion Ghia (twin Weber carburettor), or fuel-injected 105 hp (K-JetronicJetronic

1.8
The 1.8 CVH was a very rare engine, it was just used in the European Ford Sierra. There are not many differences to the 1.6 engine. Bore was still 80 mm, but a different crankshaft with a stroke of 88 mm gave the engine its higher capacity. The cylinder head was equipped with hydraulic roller camshaft followers to reduce noise and help the engine to run smoother.1.9
The CVH was bumped up to 1.9 L for the North American 1986 model year Escort. Bore was now 82 mm (3.2 in) and stroke was up as well to 88 mm (3.5 in). This stroke length would be used in the 2.0 L CVH engines, and continued into the ZetaFord Zeta engine

2.0
The 2.0 L was introduced in the 1997 Escort (North American) sedan and wagon as SPI2000 (Split Port Induction). It now used split port induction and produced 110 hp and 125 ft·lbf (169.5 N·m). The additional displacement was achieved by boring the 1.9 L engine to 84.8 mm (3.3 in). It's the smoothest and quietest CVH engine made, and continued to deliver excellent fuel economy, although due to the cars' increased weight, mileage is somewhat less than earlier models (usually mid-20s city, mid-30s highway). As with the 1.9, the water pump is driven by the timing belt. This engine is an interference design: the valves can collide with the pistons if the camshaft and crankshaft rotate independently of each other. It is the last CVH engine made and saw an end to production in the last of the 2004 Ford Focus LX/SE sedan and wagons.Applications
