VanDyne SuperTurbo Inc. has recently completed Phase I of an Army SBIR project entitled “Diesel Waste Heat Recovery Utilizing a SuperTurbocharger”. The project focused on modeling a SuperTurbocharger for a specific Army application and evaluating the potential benefits from a single device capable of supercharging, turbocharging and turbocompounding. The modeling effort resulted in predicted efficiency gains from both air flow management and mechanical waste heat recovery. Additionally, the modeling program revealed additional engine power available that was inaccessible with the engine’s current turbocharged configuration. This paper will cover the fundamentals of the technology, the Phase I engine modeling results and the path forward for the Phase II prototype testing project.
