Slide 1

A vehicle’s engine is the source of its power. Although diesel-fuel-powered engines come in a wide variety of sizes, models, and design, the basic operating principles of all engines are the same. Almost all freight-hauling trucks (and most other heavy-duty vehicles) contain four-stroke, diesel-fuel-burning engines.

Slide 2

Tracks are necessary to provide the flotation, traction and mobility that machines need to work in soft, rough or uneven terrain that rubber tires cannot provide.

Slide 3

The modern vehicle powered by a diesel engine is an amazing piece of technology, with its many components working together to safely and reliably haul freight, transport passengers, and serve the construction and farming industries.
