The Ford Pinto engine was the unofficial name for a four-cylinder internal combustion engine built by Ford Europe. In Ford sales literature, it was referred to as the EAO or OHC engine and because it was designed to the metric system, it was sometimes called the "metric engine". The internal Ford codename for the unit was the T88-series engine. European Ford service literature refers to it as the Taunus In-Line engine (hence the TL codenames). In North America it was known as the Lima In-Line (LL), or simply the Lima engine due to its being manufactured at Lima Engine in Lima, Ohio.
It was used in many European Ford cars and was exported to the United States to be used in the Ford Pinto, a successful subcompact car of the 1970s, hence the name which is used most often for the unit. In Britain, it is commonly used in many kit cars and hot rods, especially in the 2-litre size.
In Europe, the Pinto OHC was introduced in 1970 to replace the Essex V4 used in the Corsair as that range was subsumed into the Mk3 Cortina and Taunus V4 for the German Fords range (mainly the new Taunus TC). It was the first Ford engine to feature a belt-driven overhead camshaft (thus the name). Early Pinto engines suffered from excessive cam and follower wear, this was later addressed by nitriding the cam lobes and followers, and the fitment of a spray bar, which sprayed oil directly at the camshaft. All standard production Pinto engines had a cast iron cylinder block and a cast iron, crossflow, single overhead camshaft cylinder head with two valves per cylinder operated by finger followers.
Applications:
The Pinto engine was available in five displacements: 1294cc, earlier 1593cc, later 1598cc, 1796cc and the 1993cc. Later 1998cc. Due to emission requirements, it was phased out towards the end of the 1980s to be replaced by the CVH engine and DOHC engine, the latter being (contrary to popular belief) a completely new design and not a twin-cam development of the Pinto unit. The only DOHC direct derivative of Pinto engine is the Cosworth YB 16-valve engine, powering Ford Sierra and Ford Escort RS Cosworth variants and featuring a cast aluminium alloy cylinder head developed specially by Cosworth fitted to a modified Pinto cast iron block.
The final Pinto engines used in Ford of Europe production vehicles were the 1598cc litre versions used in the Sierra until 1991, and the last 1998cc units were used in the Transit until 1994.
The smallest member of the family was the 1294cc which had a NaN2NaN2 bore and stroke.It was produced in two compression ratio versions:
The fuel was supplied by the Motorcraft single-barrel (1V) carburetor in the early models (until April 1979), and Motorcraft VV ("variable venturi") carburetor for the vehicles built after April 1979.
Applications:
Initially, the 1593cc had a bore of 87.72NaN2 and shared the crankshaft with the 1.3 L model with a stroke of 662NaN2 giving the displacement of 1593cc.The TL16L had a compression ratio of 8.2:1 and developed 48- of power and 111- of torque depending on the carburetor and application. As the 1.3 L model, it used the Motorcraft 1V and, later, the Motorcraft VV carburetors. The engine code of the low compression variant started with 'LA'.
Applications:
The HC version of the early 1593cc had the same bore and stroke as the LC version, but the compression ratio was higher (9.2:1), allowing it to produce 530NaN0 of power and 1180NaN0 of torque. It used the same carburetor models as the low compression version (Motorcraft 1V and Motorcraft VV).
Applications:
From the beginning of the production run, the 1593cc had a special, 'sporty' version which featured:
With such an improvement package, the engine produced 660NaN0 of power and 1250NaN0 of torque.
Applications:
1970-1976 Ford Cortina GT (engine code LEA)
At the beginning of 1984, Ford Pinto engine displacement range switched from 1.3/1.6/2.0 to 1.6/1.8/2.0. The newly introduced 1.8 L engine used the 2.0 L crankshaft, so to uniform engine parts for the whole range after dropping the 1.3 L — the 1.6 L was redesigned to also take the 2.0 L crankshaft which had a 76.95mm stroke. This of course led to bringing the bore down to 81mm to keep the displacement within range — it was now 1598cc. The TL16E became now the only available 1.6 L engine of the Pinto range. Although the compression ratio was raised to 9.5:1, the power figures did not differ much from the earlier TL16H version — the engine developed 560NaN0 of power and 1230NaN0 of torque.This engine is sometimes referred to as 1.6 E-Max engine.
Applications:
The 1798cc Pinto engine was introduced in 1984 as a replacement for the "old" 1.6 L. The engine had an 86.22NaN2 bore and 76.952NaN2 stroke giving the displacement of 1796cc. Output was 660NaN0 of power and 1400NaN0. Fuel was supplied by the Pierburg 2E3 28/32 carburetor.
Applications:
The 1993cc was used in many Ford vehicles from the early 1970s. Due to its robustness and high tuning potential, it was often used as an aftermarket engine upgrade or base for building race and rally engines — not exclusively in Ford cars. The engine has bore of 90.82NaN2 and 772NaN2 stroke giving the displacement of 1993cc.It was manufactured in several variants:
Three completely different LC variants of the 2.0 L were produced.One was used on the 1970–1982 Ford Taunus export version to Sweden — fitted with the Weber DGAV 32/32 carburetor and compression ratio lowered to 8.2:1 to meet the rigorous emission specifications; it delivered 640NaN0 of power and 1400NaN0 of torque.The second one was used on 1978–1991 Ford Transits and P100 models. With modified induction and Motorcraft 1V carburetor, it produced 570NaN0 of power and 1560NaN0 of torque available at only 2800 rpm. The compression ratio in this case was also 8.2:1. The Transits also used the third variant called the "Economy" engine. The power figure of this one was even lower — it developed only 430NaN0.
Applications:
Although Ford marked its standard 2.0 L engine as HC, it actually uses engine codes meant for the 'increased performance variant' engines (coding starting with 'NE'), these have a compression ratio of to 9.2:1.This engine used different carburetor models across the years:
The engine produced 740NaN0 of power and 1560NaN0 of torque, though a few models with a higher output were produced (for example an 810NaN0 version used in 1976 Ford Escort RS2000).
Applications:
The injected 2.0 L used the Ford EEC-IV engine control system which brought the output up to 850NaN0 of power and 1600NaN0[1] of torque, although much of this increased performance can be attributed to the improved design of the EFI variants cylinder head.[2] As the EEC-IV installation on most of those engines contains some Bosch parts that are easily visible in the engine compartment (air flow meter of the electromechanical "flap" type, injectors, fuel pressure regulator etc.), it is often - but falsely believed that they are fitted with the Bosch L-Jetronic injection system.Some of the TL20EFI engines have closed-loop lambda control, while others are lacking that feature.
Applications:
This variant was used in Ford Transit exclusively. The power output was 570NaN0.
Applications:
In the beginning of the 1980s, Cosworth developed a 16-valve performance head conversion for the Pinto engine. This was seen by a Ford executive who asked Cosworth to develop it with a turbo for use in the new Ford Sierra RS Cosworth.The engine is therefore based on a modified Pinto block topped with the Cosworth-developed alloy head and Garrett turbo.
The 2.0 litre version was a narrower-bore version of the original 2.3 liter "Lima" four. Bore and stroke are 89.3and, respectively, for an overall displacement of 1990cc. This engine was installed in the 1983-1988 Ford Rangers and in some Argentinian Ford Taunus.
The Ford Pinto used the OHC version, a 2301cc unit introduced in 1974 which has a 96.042NaN2 bore and 79.42NaN2 stroke. This version lasted until 1997 in various guises. The earliest units produced 660NaN0 and 1600NaN0. This engine has also been known as the Lima engine, after the Lima Engine plant in Lima, Ohio, where it was first manufactured (it was also manufactured in Brazil starting in 1974).
In 1979-80, a draw-through, non-intercooled turbo version was produced for Mustang Cobras and some Capris. Lack of dealership and owner training resulted in many stuck turbochargers and other maintenance problems. They were limited to 5psi of boost, though Ford Motorsport sold a wastegate with an adjustable rod which allowed an increase up to 9psi. It was used in this carbureted form in a number of passenger cars, from the Fairmont Futura Turbo to the 1979 Indy Pace Car edition Mustang.
In 1983, Ford introduced a fuel-injected version of the turbocharged engine, which was used in the Thunderbird Turbo Coupe and the Turbo GT trim of the Mustang. In 1984, the Mustang SVO was introduced with an intercooler, initially producing 175hp and later increased to 205hp in 1985½. After the SVO was discontinued, the intercooler was added to the Turbo Coupe. Output for this turbo/intercooled version was 190hp and 2400NaN0 for the 1987-88 models with the five-speed (T-5) manual transmission. In addition to the 1983-1984 Mustang Turbo GT and 1983-1986 Turbo Coupe, the non-intercooled version of the engine was also used in the 1985-89 Merkur XR4Ti and 1984-1986 Mercury Cougar XR7, producing 155hp and 1900NaN0.
A dual-spark version (with two spark plugs per cylinder, distributor-less ignition, and reduced main bearing sizes) was introduced in the 1989 Ford Ranger and 1991 Ford Mustang. This version produced 1050NaN0 and 1830NaN0.
A stroked by 7mm version of the 2.3 OHC Ford Ranger engine appeared in 1998 yielding 2504 cc. In addition to the longer stroke, it used higher-flow cylinder heads utilizing narrower 7mm valve stems. Crankshaft counterbalance weights were increased in count from 4 to 8. Output was 1190NaN0 and 2020NaN0. It was replaced in 2001 by the Mazda-derived Duratec 23, but Ford Power Products continues to sell this engine as the LRG-425.
