Small Engines Designed for High Efficiency, High Power Density and Quiet Operations

XRD Inc. will deliver a feasibility study and work plan to produce engines operating on heavy fuel that meets the objectives of Program Solicitation entitled “Small Engines designed for High Efficiency, High Power Density and Quiet Operations”. The goal is to have power density greater than 1 hp per pound and greater than 25% thermal efficiency while operating on available heavy fuels. This new design will be based on current existing operating XRDi engines which already use military fuels. These designs, using our patented technology, have already met heavy fuel engine requirements including: • Operation on a variety of fuels with no recalibration (JP5, JP8, Jet-A, diesel, gasoline) • Cold start demonstrated @ -30 °C (with no aids) • BSFC of < .49 lb/hp-hr @ cruise • Operation demonstrated @ 26,000 ft density altitude The 35 hp and 12 hp engine can be seen running with heavy fuel on a video at www.xrdi.com as well as a presentation of the technology. XRDi’s approach is to utilize our existing proven heavy fuel technology and apply advanced materials, perform component optimization using computer based simulation and modeling tools and apply system engineering techniques to meet the goals and objectives as outlined.
