Ultra-Efficient Gas Engine Passes Test

A novel fuel-injection system achieves 98 miles per gallon

It plans to build its first factory in 2013, and to introduce the technology into production cars by 2014






Transonic Supercritical Fuel Injection


















believes much better fuel efficiency will be achievable when the Sonex Controlled Auto Ignition (SCAI) system is fully developed for Gasoline Direct Injected (GDI) engines using no spark ignition or throttle. The Sonex GDI Combustion System could improve fuel mileage by at least 25%.
