Abstract

The first known broadband single-pulse coherent anti-Stokes Raman scattering (CARS) measurements within the cylinder of a firing internal combustion engine are reported. Postcombustion temperature and carbon monoxide concentration are probed with 1-mm3 spatial resolution and 10-nsec temporal resolution. Space- and time-resolved measurements, as presented here, are shown to be necessary for the study of fluctuating systems such as engines.
