Description
Summary:An analysis system is described which is composed of a Fourier transform infrared spectrometer, a quadrupole mass spectrometer, a total hydrocarbon analyzer, and a PDP 11/23 microcomputer as a data logger. This analysis system allows on-line, simultaneous measurement of a multitude of engine operating parameters, regulated emissions, and non-regulated emissions. The measured engine operating parameters include: air/fuel ratio, exhaust volume flow, hydrogen/carbon ratio of the fuel, and instantaneous fuel economy. Data are presented demonstrating the system's ability to reveal correlations among engine operating parameters and emissions, for both catalyzed and non-catalyzed exhaust emissions from methanol fueled engines. Data are also given comparing the analysis system with conventional instrumentation. The system provides exhaust composition, engine operating parameter data, and mass per mile emission rates with a 3 second time resolution without the use of a CVS unit.
