Abstract

High speed cind photography has been used extensively in combustion research work carried out in the Mechanical Engineering Department at Leeds University. The experimental techniques adopted are presented and discussed, in particular, experiments that have been conducted on 'Turbulence and Combustion Rate in Homogeneous Charge Spark Ignition Engines'. Analysis of the 16 mm cine film enabled the flame progress to be charted when photographed through a modified perspex cylinder head. Comparison is made between single and dual, or divided, chamber cylinder heads. The cylinder head geometry is changed by using different pre-chamber sizes to vary the volume ratio and the interconnecting orifice size is also varied. The dual chamber engine is suggested to be a useful vehicle for genera-ting fundamental data, of a general nature, for turbulent burning rate in an S.I. engine and for validating mathematical models of such engines.
