Abstract:

In a program sponsored by the U.S. Army Belvoir Research, Development and Engineering Center, researchers at Southwest Research Institute have been developing a new procedure for rating the ignition quality of fuels for diesel engines. The ultimate goal is to develop a new scale to replace the current cetane scale and procedure. The preliminary goal, however, is to develop an apparatus and procedure to determine cetane number using ignition delay time as determined in a small constant-volume combustion bomb. The development activities have involved experiments designed to determine the relationship between the various experimental variables, experiments designed to assess the quality of the cetane determinations, and development activities designed to improve or refine the calibration and test procedures. This report is a summary of the findings of these experiments and a discussion of the validity of the techniques for cetane determination.
