Description

There have been a few catastrophic Caterpillar engine failures, but the 3406E is not one of them. The CAT 3406 engine is available in four different models: A, B, C, and E. It later developed into the CAT C15 and then the CAT C15 Acert. This was a very good engine for CAT because it was the first properly evolved electronic engine. The Caterpillar 3406E engine was so common in the mid-90s and early 2000s that it was used in the vast majority of Peterbuilt trucks.

The ECM architecture was simple to work with, and it quickly gained a following of programmers who could write a wide range of applications for the engine. The ECM’s “open source” design allowed end users to “hot rod” the engine by changing the injectors, camshaft, or valve timing to increase horsepower and torque. The CAT 3406E is still in use in millions of on-road and off-road applications around the world in 2016. In general, Caterpillar is regarded as the undisputed king of diesel engines.
