A750-HP aircooled diesel engine has been successfully developed with the primary purpose of reducing the fuel consumption of gasoline-engined-powered combat vehicles by approximately 40%. The new powerplant is characterized by low fuel consumption, light weight, and high compactness.
The basic features of the engine are: 5.75-in. bore × 5.75-in. stroke, 1790-cu in. displacement, compression ignition, 4-stroke cycle, direct-injection system, 90-deg Vee, 12-cyl, aircooled, exhaust turbocharged. Rated output is 750 hp at 2400 rpm with a potential output increase up to 850 hp.
Engine oil coolers transmission oil coolers, and cooling fans are mounted on the engine and form an integrally cooled powerplant.
