The objective of this paper is to investigate appearance of surface ignition - postignition experienced inside the engine cylinder and correlate it with the nature of the spark ignition combustion prior to the onset of surface ignition. The test engine used to carry out all experiments was a Jaguar optical single-cylinder engine, operating in spark-ignition mode, although with negative valve overlap. The optical configuration of the engine allows characterizing and analyzing combustion process based on the processing of captured images in correlation with in-cylinder pressure and other parameters recorded with regard to instantaneous engine operating conditions. Results of the experiments covered in this publication focus on flame propagation and development as well as reveal occurrence of abnormal combustion processes. Experimental observations, especially the captured images show a relationship between the nature of normal combustion process initiated by spark discharge and the existence of abnormal combustion phenomena. All tests were performed under fixed engine conditions - constant speed and single component hydrocarbon fuel. Because the nature of fuel can shape the combustion process, a brief discussion and a proposed correlation of anti-knock, auto-ignition, and resistance to surface ignition qualities of a few single- and multi-component fuels is presented. Finally the publication leads to provide an indication of possible solutions concerning the problem of uncontrolled post-ignition events in optical engines.
