【 摘 要 】

This is the final report of a three-year project under a Department of Energy Advanced Reciprocating Engine Systems contract. The goal of this project is to develop advanced sensors for real-time combustion monitoring of advanced natural-gas reciprocating engines. Two sensor technologies, ion-mobility spectrometry (IMS) and acoustic gas sensing, were tested for detection of NO{sub x} emissions and monitoring of natural-gas composition. This project examined two novel approaches: use of a corona/spark-discharge ionization source for IMS, and acoustic-relaxation spectra of natural gas for the acoustic gas sensor. We have completed evaluation of laboratory prototypes of both sensors. In this report, we will describe the basic elements of the sensors, their operating and detection principles, their performance, and other issues. Design modifications and suggested applications of field prototypes will also be presented.
