History of the 4.0 Jeep engine

AMC and Chrysler began producing 4.0 jeep engines in 1987, AMC built a 4.0 engine in 1986, and a year after Chrysler bought AMC, Chrysler kept making required changes to the engine.  Then, after its two-decade journey, numerous modifications were made to bring the best out of it. The major changes include focusing on higher fuel injectors in 1988; in 1991, RENIX was replaced by multi-port fuel injection, intake ports were raised by 3.2mm; the throttle body was enlarged, and updates were made in the intake and exhaust manifold and also in cam timing methods.

1991 was a major year because it also raised the horsepower from 173 hp to 190 hp. Gradually, in the following years, the engine block was strengthened and the cylinder head was altered. In 2000, to enhance the overall efficiency of the engine, it supported lower emissions. In the same year, the distributor-less coil on the plug ignition system was developed further. However, the production of the 4.0 jeep engine came to an end in 2006.
