Abstract
This paper describes the development of a ceramic turbocharger at Ford Motor Company, Engineering and Research Staff. The potential advantages of reduced turbocharger and vehicle response time and manufacturing cost savings have made the ceramic turbocharger rotor a subject of interest to automotive, ceramic, and turbocharger manufacturers. An Ishikawajima-Harima Heavy Industries Co., Ltd. RH06 turbocharger was modified to incorporate a slip cast reaction bonded silicon nitride rotor to evaluate the effect of reduced rotary inertia on vehicle performance. The results of vacuum spin pit testing, turbocharger test cell testing, 2.3L spark ignition dynamometer tests, and preliminary vehicular tests, are reported.
