A FLOATING-POINT COPROCESSOR FOR FAULT DETECTION AND ISOLATION IN ELECTRONICALLY CONTROLLED INTERNAL COMBUSTION ENGINES. FINAL TECHNICAL REPORT

This report details the design of a floating-point coprocessor intended for real-time fault detection in electronically controlled internal combustion engines. The fault detection strategies are based on dynamic models of various engine subsystems and require the use of state estimators. This coprocessor can be operated at a clock rate of 24 MHz, and is capable of operating up to sixteen state estimators in real time. The design is suitable for application to internal combustion engines used for vehicle propulsion or power generation, whether diesel or spark ignited.
