The 2.2 and 2.5, also known as the Trenton Engine due to their manufacturing location, are a family of overhead cam inline-4 engines developed by Chrysler Corporation originally for the Chrysler K- and L-platforms cars and subsequently used in many other Chrysler vehicles. 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. It was the first Chrysler-engineered four-cylinder engine since the Chrysler flathead four-cylinder was discontinued in 1933. The engine block and valvetrain were not derived from the overhead valve Chrysler LA series V8 that was in production then.
