The Navistar DT (Diesel Turbocharged or Diesel Turbo) engine family is a line of mid-range inline-6 diesel engines.With horsepower ratings ranging from 170 hp (130 kW) to 350 hp (260 kW), the Navistar DT engines are used primarily in medium-duty truck and bus applications such as school buses, although some versions have been developed for heavy-duty regional-haul and severe-service applications.
The first IHC "Highwheeler" truck had a very simple air-cooled horizontally opposed two-cylinder engine with a 5-inch (130 mm) stroke and a 5-inch (130 mm) bore, and produced around 18–20 hp (13–15 kW).
