HEUI Diesel Injection System Overview

The hydraulically actuated electronic unit injector was technology developed by Caterpillar in the early 1990’s. The most popular application of this technology was arguably the 7.3L and 6.0L Power Stroke diesel engines designed by International Navistar and used heavily in Ford 3/4 and 1 ton pickups. In fact, the International T444E and 7.3L Power stroke are reportedly the first engines to employ the new technology on license from Caterpillar. Since then, the application has expanded to several models including the

Caterpillar C7/C9 & 3408/3412 engines. A major benefit of the HEUI injection system was engine control, as the characteristics of injection events can be controlled independently of any mechanical system. The results were cleaner emissions and greater fuel economy potential.
