Chrysler 2.2 & 2.5 Engine - 2.2

2.2

The first version of this engine family was a normally aspirated 2.2 L (134 cu in) unit. 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 2.2 has an undersquare 87.5 mm (3.44 in) bore and 92 mm (3.62 in) stroke, which gives it a displacement of 2,213 cc (135.0 cu in). It is a siamesed engine: there are no coolant passages between cylinders. The bore spacing is 87.5 mm (3.44 in), limiting the potential for increased bore diameter. All 2.2 engines have cast iron blocks, use a timing belt, and are non-interference engines. The earliest version used a two-barrel carburetor, but fuel injection was introduced in 1984 on turbocharged models and 1985 on normally aspirated models (it is used on all 2.5 liter engines).

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). Later versions were fuel-injected and produced 93 horsepower (69 kW) to 99 horsepower (74 kW) and 121 lb·ft (164 N·m), and a High-Output version for the Dodge Charger produced 110 horsepower (82 kW) and 129 lb·ft (175 N·m).

Four 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 primary difference between these engines was the use of an intercooler (in all except Turbo I). 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 Turbo IV pioneered the use of variable nozzle technology to minimize lag.

The 2.2 was made at Chrysler's Trenton Engine plant in Trenton, Michigan. In 1995, Chrysler sold much of the machining equipment, as well as a license to the design, to First Auto Works of China. 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.
