1982–1990 Chrysler LeBaron (fuel-injected after 1985).Design work on the six had started in 1975, with the 2.2 added to the program in 1980, but due to labor unrest in Canadian automobile manufacture and the collapse of the diesel market in North America, Lee Iacocca suddenly and unilaterally cancelled these plans in 1983. In 1982, Chrysler also signed an agreement with Perkins Engines to build a dieselized version of the 2.2 (and of the 3.7-liter inline-six) in Windsor, Ontario. The Trenton plant largely switched to the new Chrysler 3.3 engine production, while FAW continues to build the 2.2, which they used in their version of the Audi 100. In 1995 Chrysler sold much of the machining equipment as well as the license to the design, to First Auto Works of China, after negotiations which had begun in the mid-eighties. The 2.2 was made at Chrysler's Trenton Engine plant in Trenton, Michigan. The Turbo IV pioneered the use of variable nozzle technology to minimize lag. The Turbo III, ironically developed after the Turbo IV, pioneered returnless fuel injection, and was coupled to high-performance, four-valve-per-cylinder heads, bringing 224 horsepower (167 kW) from the 2.2 liter engine. The primary difference between these engines was the use of an intercooler (in all except Turbo I). Later versions were fuel-injected and produced 93 horsepower (69 kW) to 99 horsepower (74 kW) and 122 lb⋅ft (165 N⋅m), and a High-Output version for the Dodge Charger produced 110 horsepower (82 kW) and 129 lb⋅ft (175 N⋅m).įour series of turbocharged 2.2 and 2.5 liter engines were produced, normally referred to as Turbo I, Turbo II, Turbo III, and Turbo IV. The initial carbureted 2.2 initially produced 84 horsepower (63 kW), but the output was increased to 96 horsepower (72 kW) and 119 lb⋅ft (161 N⋅m). In 1985 fuel injection became optional on the lower end models (Dodge Omni/Plymouth Horizon, Dodge Aries/Plymouth Reliant), eventually replacing the carbureted variant across the board. Fuel injection was standard on some higher end models such as the Chrysler E-Class, Laser, and New Yorker, and the Dodge 600 and Daytona. The earliest version used a two-barrel carburetor, but fuel injection was introduced in 1984 on both turbocharged and normally aspirated models (it is used on all 2.5 liter engines). All 2.2 engines have cast iron blocks, use a timing belt, and are non- interference engines. The bore spacing is 96 mm (3.78 in), limiting the potential for increased bore diameter. It is a siamesed engine: there are no coolant passages between cylinders. Developed under the leadership of Chief Engineer – Engine Design and Development Willem Weertman and head of performance tuning Charles "Pete" Hagenbuch, who had worked on most of Chrysler's V-8 engines and the Chrysler Slant-6 engine, it was introduced in the 1981 Dodge Aries, Dodge Omni, Plymouth Horizon and Plymouth Reliant, and was produced until 2000. The first version of this engine family was a normally aspirated 2.2 L (134 cu in) unit. It was the first Chrysler engineered four cylinder engine since the Chrysler flathead four cylinder was discontinued in 1933. After its launch in 1981, it became the basis for all Chrysler-developed 4-cylinder engines until the Chrysler 1.8, 2.0 & 2.4 engine family was released in 1994. The 2.2 and 2.5 are a family of inline-4 engines developed by Chrysler Corporation originally for the Chrysler K- and L-platforms cars and subsequently used in many other Chrysler vehicles.
