This paper discusses today's DI-engine problems with fuel-injection hydraulics, swirl, improper valve-timing and Air Cycle; and the threats they pose to the industry. We believe that fresh Divided-Chamber designs, with new thinking on valve timing, injection, and the combustion process itself, can solve those problems. This paper presents all-new four-valve designs, with radial valves and radically-new central Prechambers or Energy-Cells; the last with new injection concepts; all with optional Variable Valve Timing/Variable Effective Compression Ratio (VVT/VECR). These approaches are designed to increase output with reduced fuel consumption, emissions and noise; providing, quickly and economically, the alternative solutions needed for future engines.
