Combined Technology Solutions, LLC — Department of Energy SBIR Phase I: 17e

Description

This SBIR proposal focuses on new ignition technologies which can operate a spark ignited internal combustion engine using lean burn techniques that typically impede reliable combustion in engines used in automobile applications. Prototype ignition systems for this topic need to ignite air fuel ratios greater than 20:1, operate at high pressures, be tolerant of exhaust gas recirculation and accomplish this while maintaining smooth operation. Achieving lean burn operation may require novel methods as well as advanced equipment. While not directly mentioned in the scope, these efforts may provide an opportunity to improve fuel economy by a substantial amount and reduce primary exhaust emissions as well. The Phase I will identify technologies which can accomplish a level of lean burn stability that can be expanded into a Phase II SBIR which will identify the exact equipment, controls and methods that will enable automotive engines to use lean burn processes to dramatically reduce fuel consumption for the general public, reducing our dependence on foreign oil and reducing the carbon footprint. Industrial engines use lean burn technologies to reduce NOx emissions to meet EPA regulations. While their ignition source is difficult to adapt to the automotive, the basic premise of operation provides the first clues. The companies who provide low NOx emissions technologies to the natural gas fuel industrial engine market should have lean burn experience that may be combined with automotive technologies to provide a marketable solution. The solutions provided under this DOE topic may have worldwide implications and cross market applications, such as generators, pumps, etc. The ignition robustness and lean burn process may be applied to fuel sources other than petroleum based.
