Student and instructor standing at a computer in the diesel shop, with diesel engines and equipment all around them

Diesel engines are used in trucks, tractors, construction machines, power generation, boats, and trains. The transportation industry depends on diesel power to move the world’s goods.

The widespread use of diesel equipment allows diesel service technicians to work in a shop or field service. As a diesel technician, you could work on a construction job, in the woods with a logging operation or at sea on a tug or fishing boat.

The Oregon Employment Department forecasts diesel mechanic employment in the Portland area will grow 14.1% through 2027.
