Effects of Ceramic Surfaces on Autoignition in a Constant Volume Combustion Apparatus.

Abstract

A constant volume combustion apparatus was used to determine the effects of ceramic-coated surfaces on the ignition of fuel sprays from a diesel injection nozzle. The goal was to determine if the ceramic surfaces could enhance ignition through catalytic effects on the surfaces. Statistical analysis of the data indicated that an aluminosilicate coating had no effect, while a partially stabilized zirconia increased the delay times. It appears, however, that the aluminosilicate coating could actually enhance the ignition, producing shorter ignition delay times, if the results of the appropriate baselines are considered. Keywords: Ignition, Ceramics, Catalytic surfaces.
