Continuous Monitoring of Diesel Exhaust Gas for Carbon Dioxide, Carbon Monoxide, Oxygen, Methane, and Nitrogen Oxides

摘要

The report describes a monitoring system to provide rapid, continuous determination of the main constituents of exhaust gas during the testing of diesel engines for underground use. Commercially available continuous analyzers with strip chart readout are employed for nitric oxide (mass spectrometric), carbon dioxide (nondispersive infrared), methane (NDIR), carbon monoxide (NDIR), and oxygen (polarographic). Good correlation is obtained between the continuous instrumental results and those obtained by batch chemical and gas chromatographic methods. (Author)
