Model AVDS-1790-2C Series Diesel Engine

The CPS AVDS-1790-2C Series engine is an air-cooled, 90 degree upright Vee deisgn, 12 cylinder turbocharged diesel engine - rated at 750 gross horsepower at 2400 rpm. Air cooling for engine cylinders, as well as engine driven fans 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-1790-2C 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.

The engine is capable of starting and operating at temperatures from minus 25 degrees to plus 125 degrees Fahrenheit (minus 65 degrees with starting aids). It will also operate while totally submerged in water, with the aid of an intake snorkel.

The AVDS-1790-2C Series engine is an improved version of the CPS AVDS-1790-2A Series diesel engine. It is specifically designed to accept an oil cooled 28V alternator - rated at 650 amps.
