Summary

We report on the dynamic car exhaust gas analysis with single ignition cycle resolution. the optical setup using pulsed integrative IR diode laser spectroscopy as well as the fast sampling system are described. Preliminaary NO and CO measurements on a one cylinder engine with a time resolution in the ms range are presented.
