* Light-duty trucks: While less common than in heavier applications, some custom builders and older trucks may utilize them.
* Medium-duty trucks: This is a more typical application, frequently found in box trucks, delivery vehicles, and other commercial trucks in the 10,000-26,000 GVW range.
* Buses: Smaller buses, shuttle buses, and some specialty buses have used the 4BT.
* Construction and agricultural equipment: Skid steers, forklifts, and other similar machinery often employ the 4BT for its power and reliability.
* Marine applications: The 4BT is also found in some smaller boats and marine vessels.
* Industrial equipment: Generators, pumps, and other stationary equipment.
It's important to note that the 4BT is generally *not* found in passenger cars or larger, heavy-duty trucks (those applications usually utilize larger Cummins engines). The engine's popularity stems from its reliability, relatively compact size, and decent power output for its class.
