Study of Heated Exhaust Gas Oxygen sensor downstream of the catalyst as an emissions calibration tool 2008-36-0319

Vehicle emissions development is a costly and time-consuming process, with numerous iterations in emissions laboratory. Besides the high cost of such tests, the limitation on the availability of that resource may be a serious obstacle to development timing.
The objective of this study is to perform statistical comparisons between the second-by-second modal analysis of emissions laboratory analyzers, and the voltage signal of a heated exhaust gas oxygen sensor placed downstream of the catalyst, in order to assess the usage of such sensor as an auxiliary tool to calibrate closed loop fuel control, aiming NOx tailpipe emissions, out of the laboratory.
