4.5 Liter Opposed-piston engine development for improved power density

Baker Engineering Inc. proposes a 4.5 liter opposed-piston, 3-cylinder, 2-cycle diesel engine with a target of 500 hp, weighing less than 900 lbs. to fulfill the Army's quest for an improved power density, multi-fuel capable and low heat rejection compression engine. This 4.5 liter engine offers an opportunity to further advance the opposed-piston combustion technology by building upon the successes proven through previous opposed-piston engine development and testing efforts (prototype engines ranging from 4.1 liter to 8.3 liter). The proposed new 4.5 liter engine design will advance the design of pistons, rods, cranks and other core opposed-piston engine components with the primary emphasis on improving the fuel delivery system and controls, adding a self-sustained turbo charger system, reducing weight, and improving packaging.
