Diesel Waste Heat Recovery Utilizing a SuperTurbocharger

The VanDyne SuperTurbocharger a single device capable of supercharging, turbo charging and turbo compounding. The device mechanically controls the speed ratio between the engine crankshaft and the turbine/compressor. The SuperTurbocharger allows for improved engine transient response, increased power levels and an increase of overall fuel efficiency. During Phase I of this SBIR, VanDyne has completed GT-POWER modeling to verify the applicability of the device for the CAT 18L engine utilized in the Armys HET-A1. BSFC gains for targeted operating points exceed 6% and fuel efficiency is improved across all operating points. Turbo lag is eliminated and maximum engine power has been enhanced. An additional patent has been filed as a result of this work. During Phase II, a prototype will be developed for this application and tested in a laboratory environment. Phase II is intended to validate and demonstrate the positive results from Phase I. VanDyne is well positioned for commercialization of the SuperTurbocharger and intends to utilize Phase III for durability and vehicle testing. This testing will be followed by production for Army applications in parallel with similar programs for automotive and industrial customers.
