This CRADA supports the objective of demonstrating feasibility and minimizing manufacturing costs associated with the use of ceramic components in a heavy duty diesel engine manufactured by Detroit Diesel Corporation (DDC). Studies were conducted to evaluate existing, known data for ceramic material, and to identify additional data needed to better characterize a valve of ceramic composition. Tests were conducted to provide important information required for redesign of existing metal valves and other engine head components. A vendor was selected by DDC to produce the valve shapes for testing and Lockheed Martin Energy Systems (LMES) provided design modeling/analysis support. The effort also included the development of a bench-test apparatus to simulate the environment of a valve in operation that provided material data and confirmation of analytical results
