Supersonic Hot Jet Ignites Ultra-Lean Fuel Mixtures in Combustion Engines
Researchers from Purdue University have developed a technique to generate supersonic hot turbulent jets that can ignite ultra-lean fuel/air mixtures, which may not be able to ignite using current pre-chamber technologies. The supersonic hot jet makes it possible to burn ultra-lean mixture in combustion engines through the use of converging-diverging nozzles with a certain aspect ratio in the pre-chamber. Supersonic jet ignition improves combustion efficiency, reduces NOx emissions, and increases fuel economy.
