Case Example 2: Data analysis for diagnostics and process monitoring of automotive engines

This case example describes software for analysis of data from cold tests of fully and partially assembled engines. Cold testing of engines (testing without fueled running) at engine assembly plants has attracted considerable interest for its potential to reduce test costs and improve product quality. Cold testing of newly manufactured engines offers several advantages over traditional ‘hot’ tests (fueled, running tests): Speed: fewer hookups and detachments, shorter overall test time. Cost: less expensive test and facility hardware; cold testing also offers improved safety and environmental conditions. Quality: extremely sensitive to mechanical deviations which affect performance and therefore much lower probability of missing a failure. Coverage: wide range of potential defects can be detected and identified.
