Small Engines Designed for High Efficiency, High Power Density and Quiet Operations
Agency / Branch:
DOD / DARPA
This program will establish a very quiet, fuel efficient and high power density engine and generator that can operate on JP-8 and diesel. It will be significantly lighter than existing engines and generators. The proposed approach will use an internally supercharged variant of the Migrating Combustion Chamber (MCC) engine. This engine's mechanism and cycle of operation allow it to operator on low octane fuels like JP-8 and diesel without auto-ignition, detonation or wet stacking. Small MCC engines have been operated on zero octane fuel, JP-8 and diesel without auto-ignition or detonation. The MCC engine provides full expansion of the combustion gases inside the engine which increases efficiency, reduces emissions and produces a very quiet, cool exhaust. This engine will be fully integrated with a proprietary, very high power-to-weight alternator using rare earth permanent magnets. Microprocessor controls will provide for load following, stabilized power under varying loads. This system is capable of partial load operation without wet-stacking. This system is scalable from 3 kW to 15 kW and larger and includes both AC and DC outputs in one unit.
