From heavy trucks and buses, to hydraulics, locomotives and oil rigs – diesel makes our world work. The diesel engine is the workhorse powering our Nation’s trucks and buses, because it delivers more power and is more durable than its gasoline-burning counterpart. A degree in Diesel Technology from NWCCD will propel your diesel engine and repair career, and help keep vital transportation and heavy equipment industries running.


Industry Outlook

Diesel engine and equipment maintenance is growing in sophistication. Emissions criteria for diesel engines are also getting stricter via new mandates by federal and state agencies.
