This is the second of four volumes of the contract final report, which summarizes all of the work performed in a government-sponsored Automotive Gas Turbine Development Program. In this volume, results are presented for the design and development of an Upgraded Engine. The design incorporated technology advancements which resulted from development testing on the Baseline Engine. The final engine performance with all retro-fitted components from the development program showed a value of 91 HP at design speed in contrast to the design value of 104 HP. The design-speed SFC was 0.53 versus the goal value of 0.44. The miss in power was primarily due to missing the efficiency targets of small-size turbomachinery. Most of the SFC deficit was attributed to missed goals in the heat recovery system relative to regenerator effectiveness and expected values of heat loss. Vehicular fuel consumption, as measured on a chassis dynamometer, for a vehicle inertia weight of 3500 lbs., was 15 MPG for combined urban and highway driving cycles. The Baseline Engine achieved 8 MPG with a 4500 lb. vehicle. Even though the goal of 18.3 MPG was not achieved with the Upgraded Engine, there was an improvement in fuel economy of 46% over the Baseline Engine, for comparable vehicle inertia weight.
