The analysis of complex and combustible gas mixtures is typically accomplished by using bulky, complex and expensive equipment such as gas chromatography analyzers. The applications for such gas analysis range from air quality management to monitoring fuel quality to ensure an engine performance is matched to the fuel composition. A low cost gas sensor to measure the fuel quality to improve fuel efficiency is desirable.
UCR researchers have developed an inexpensive sensor to measure the energy content and fuel quality of gaseous combustible fuel. This sensor estimates the Wobbe Index in real time time and costs about $10. The sensor is confirmed to operate between -20°and 70°Celsius under pressures of -3600 Psi, with an accuracy of ±1%.
