Title

Development Of A Led-Based Sensor For Simultaneous, Time-Resolved Measurements Of Co And Co2 From Combustion Exhausts.

Abstract

A sensor was developed for simultaneous measurements of carbon monoxide and carbon dioxide fluctuations in internal combustion engine exhaust gases. This sensor utilizes low-cost and compact LEDs that emit in the 3-5/mi wavelength range which are more appropriate for practical applications than the more traditionally used lasers. An affordable, fast response sensor that can measure these gases has broad application that can lead to more efficient, fuel flexible engines and regulations of harmful emissions. LEDs have a more spectrally broad and diverging emission than lasers which presented many design challenges. The optical design software ZEMAX was utilized to overcome these challenges. CO and CO2 LED measurements are conducted in their fundamental bands centered at 4.7/μm and 4.3/μm, respectively, while a reference LED at 3.6/mi is used as a reference for H2O.
