AVDS-1790 Series diesel engines are turbocharged, air cooled 12-cylinder, 90 degree Vee configurations. Power ratings range from 750 - 1500 HP. Air cooling for engine cylinders, as well as engine oil, transmission oil, and charge air coolers, are provided by direct drivefans mounted in the center of the Vee.
Extensive use of aluminum components throughout the engine provides a high power-to-weight ratio. The compact design of the AVDS-1790 engine includes individual and easily replaceable cylinders. Overhead valves are used with an overhead camshaft in the top of the engine to facilitate rapid service. Air cooling eliminates the maintenance burden of liquid cooling systems.
