High flow, high atomization, Kinetic Direct Injectors (K-DI) with advanced injector technology. These injectors utilize a proprietary kinetic particle break-up mechanism with patented nozzles to provide smaller droplet sizes, superior fuel atomization, accurate controllability, and shorter liquid lengths versus leading conventional injectors. More than three years of research and testing have demonstrated significant improvements in fuel delivery. Engine tests show higher heat release and faster burn rates than conventional air-shear fuel injection mechanisms, resulting in improved fuel efficiency and increases in power.
