| Project Detail |
Pinnacle Engines will develop a highly efficient hybrid electric engine that, if successful, will significantly reduce petroleum consumption and carbon dioxide emissions in the U.S. Adding a unique electric powertrain to Pinnacles four-stroke, spark-ignited, opposed-piston sleeve-valve engine technology enables a fundamental leap forward in fuel efficiency. Electric motor-generators on each crankshaft will improve engine efficiency by modifying and optimizing the piston motion and resulting combustion process. Pinnacle will also evaluate direct fuel injection, high rates of exhaust gas recirculation, and a low-temperature combustion strategy, which will improve knock tolerance and reduce heat loss, pumping work, and nitrogen oxide emissions. Pinnacles proposed engine technology will reduce fuel consumption and produce lower net greenhouse gases in a cost-effective manner when compared with current generation internal combustion engines and full-hybrid electric vehicles. |
