Abstract: Busek proposes to demonstrate a small, quiet, electronically fuel injected diesel generator for powering auxiliary electrical loads on an Amphibious Combat Vehicle. The objective is to prove that an electronic fuel injection (EFI) system will enhance a single-cylinder reciprocating diesel engine to meet the desired performance objectives, by increasing its power-to-volume ratio, decreasing its fuel consumption, and decreasing its acoustic noise level. For Phase I, a full EFI system will be produced by selecting an appropriate injector and injector pump, producing a custom cylinder head, and developing a specialized engine management system. Furthermore, this Phase I will also establish that the proposed auxiliary power unit will be capable of fitting in the specified space constraint. The proposed APU will have the following capabilities: produce 7kW of power in a 220 lbs package; possess multi-fuel capability on JP-8, F24, DF-2, and DF-A; achieve reliable operation at a wide range of environmental temperatures; achieve fuel consumption less than 0.7 GPH; and achieve noise less than 80 dBA.
Benefits: A compact, lightweight, fuel efficient tactical generator has many versatile applications for DOD. This proposed generator design will weigh considerably less than other similar power rated tactical generators, making this generator highly transportable on a battlefield. Furthermore, the electronic fuel injection system makes this tactical generator more fuel efficient than all other available generators, which gives a significant tactical and cost-burden advantage, when fuel may be difficult to transport and may cost hundreds of dollars per gallon in combative locations. In addition, the use of a digital EMS on the proposed diesel generator allows easy integration to future intelligent battlefield power management systems.
