Analysis of Nitrous Oxide Emission From Gasoline Vehicles and Study of Measurement Accuracy
Published September 29, 2010 by Society of Automotive Engineers of Japan in Japan
Nitrous oxide (N2O) emission from gasoline vehicles and the accuracy of N2O emission measurement systems were investigated. As a result, N2O emission from recent low emission vehicles is extremely low level. Controls of catalyst temperature and air-fuel ratio are important to reduce N2O generation. When NOx emission decreases, N2O emission is reduced, correspondingly. In N2O measurement systems, a high sensitivity analyzer and N2O reduction in dilution air are important for improvement of measurement accuracy for CVS-Bag method.
