K series 

As a result of the oil crises in 1973 and 1979 , the interest of American customers in cars with large-capacity V8 engines dropped sharply. This development was particularly beneficial to the Japanese automakers , who imported large quantities of compact cars to the USA. In order to be able to counter its own products, Chrysler developed new K-platform automobiles and associated four-cylinder engines of the same name.

Although the new engines shared some design features with the Slant Six engines , but no common parts. With the K series, Chrysler first built engines using the metric system . The first carburetor was installed as far back as possible on the engine to increase safety in an accident. From 1984 optional gasoline injection wasoffered, which replaced the carburetor models completely from 1987.

Originally, a 2-liter engine was planned, but in the course of development, it became clear that more power was needed to sufficiently motorize the cars of the K platform for the American taste. For a variant with even more capacity, the 2.5 liter, the same cylinder head was used, but the engine block had to be built higher. From 1989 both propulsion options changed to a new "common block". Both displacement variants were also built with turbocharging . 1994 was the last year of the K series, which was replaced by newer four-cylinder.

Neon

With the succession of the K platform by the Chrysler Neon also the engines of the K series were replaced. The new Neon series shares with its predecessors design features such as the cast iron cylinder block or bore diameter, but many elements have been greatly changed. For example, the neon uses four valves per cylinder, which, depending on the version, are controlled by one or two camshafts .

The neon engine also served as the basis for the Tritec engine collaboration with BMW Mini . This was replaced by the World Gasoline Engine .
