Abstract : In-cylinder process of a direct injection (DI) compression ignition (CI) engine was studied by using the Rutgers high-speed spectral infrared (IR) imaging system and the KIVA-II computer code. Comparison of the engine measurements with the computational prediction was attempted. In order to perform the instantaneous IR imaging, a Cummins 903 engine cylinder head was modified by installing an optical access in place of one of the intake valves, which required designing a new rocker-arm mechanism. The measurements obtained using the high-speed dual spectra IR imaging system were processed by the conventional two-color method which employed soot as the radiating target. The KIVA-II program was coded in order to match engine and operation conditions to those employed in the present measurements for achieving mutual consistency of the analysis. (MM)
