Active combustion control based on fuel vapor measurements has been demonstrated to improve fuel efficiency and reduce failures of engine operation. These successful demonstrations motivate further research and development of active combustion control using laser-based fuel sensors. The first key component of this research involves the improvement of sensor performance and sensing capability. The second key component focuses on improving optical engineering of the sensors and algorithms to interpret the sensing signals, so that the control scheme can be used reliably in practical combustion devices. This research work will also provide valuable insights and experience for active combustion control based on other species (oxidizer, combustion products, or emissions) using laser sensors.
