Abstract
The objective of Phase I was to demonstrate a prototype 1 kWdiesel generator that weighed less than 50 pounds. Mainstream'sfirst prototype satisfied this requirement early in Phase I. Asecond-generation prototype was then developed with reducedengine block size and weight. A third-generation prototype willbe completed in the Phase I Option that substitutes magnesium foraluminum in the engine block. Magnesium is stronger thanaluminum and will reduce engine block weight another 33%. Thediesel engine has a shaft output of 2.8 kW and can thereforegenerate more than 2.24 kW electrical power (80% alternatorefficiency). The first, second, and third generation totaldiesel generator weights are 42.1, 40.7, and 36.5 lbs,respectively. Having exceeded Marine Corps operationalrequirements in Phase I, pre-production development and extensivelife testing of the third-generation engine will be completed inthe Phase I Option. Phase II will focus on demonstrating thereliability and maintainability of the diesel engine, optimizingthe alternator, fabricating a reduced-cost production version,and field testing by the user.
