Compact Auxiliary Diesel Generator Enhanced with Electronic Fuel Injection

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.
