Development of a Robust MEMs Based Micro Technology Engine Management and Health Monitoring System

A Micro-Electronic Controlled Combustion (MECC) system was designed in the Phase I effort and, the system will be built and demonstrated in Phase II. The low-cost microsensor to be used for primary input to the model is a pressure transducer, providing the possibility for an unprecedented level of cylinder pressure-based closed-loop control and engine health monitoring based on analysis of pressure data rather than on empirical calibrations. The goal of this effort is to extend engine control and diagnostics to microsecond resolution, allowing a robust and reliable engine controller to influence the action of a cycle based on interpretation of the previous cycle.
