The thesis is an initial study of a unique 3 cylinder geometry for naturally aspired piston type internal combustion engines (ICE). The advantages of the configuration are the production of a very compact but not necessarily light engine, thermal efficiency improvements of 15% to 20%, and the ability to operate on low octane fuels without the reduction in expansion ratio that accompanies all other ICE when their compression ratios are reduced. An increase in efficiency produces an equivalent reduction in carbon dioxide production as the fuel normally needed to produce the power produced by the improvement in efficiency is never burned. Regulated emissions of unburnt hydrocarbons, oxides of nitrogen and carbon monoxide ( ) would be controlled as they are in conventional ICEs.
