Appendix A: SBIR Success StoriesIn Appendix A: SBIR Program SBIR Phase III Success Stories...............A-6 |
SBIR Program Commercialization Success StoriesThe companies featured in this Appendix have successfully transitioned their ideas into revenue-generating products. Their success stories represent just a small part of the return on EPAs SBIR investment. The Agency applauds the success of these firms, as well as the other participants in EPA's SBIR Program.
ENOX Technologies, Inc. ENOX Technologies, Inc., in Natick, MA, has developed a plasma combustion ignition system that assures ignition stability and complete combustion in lean-burn engines. The patented INOx system significantly lowers combustion temperature, improves engine efficiency, reduces nitrogen oxide (NOx) emissions, extends engine life, and reduces required engine maintenance. The INOx system is able to ignite very lean air/fuel ratios in an open chamber cylinder design, with no engine modification or tear down. The technology produces a continuous electrical discharge at the gap of a conventional spark plug for any desired number of degrees of engine rotation. The energy delivered ensures that combustion will occur even at the leanest conditions. |
Conventional technology needed to meet CAAA requirements was costing as much as $750,000. The INOx system costs only $40,000 to $102,000 and can be installed quickly because it requires no modification of the engine's head. Impact of Commercialization. ENOX has successfully retrofitted over 100 engines with its patented INOx technology. In 1995, the INOx ignition system was placed among "the most technologically significant new products" in the world when ENOX received the prestigious R&D 100 Award. The companys success with INOx was again recognized in |
Installation of the INOx ignition system on a typical gas engine compressor. The INOx system causes NOx emissions to drop by consistently and completely firing very lean air/fuel mixtures from increased turbocharger boost pressures and thus reducing combustion temperatures. This leads to lower NOx formation rates and reduced NOx concentrations in the exhaust. In addition, it produces more stable engine performance from extended duration discharge. |
