INLET MANIFOLD REQUIREMENTS FOR LOW EMISSIONS

The article describes a theoretical investigation into engine manifold requirements to provide a given level of fuel evaporation. Other aims were to understand the further evaporation processes during compression and combustion processes, and also, the effects of remaining liquid fuel on the formation of unburned hydrocarbons and carbon monoxide. The investigation is limited to a single-cylinder engine and evaluates manifold length, temperature and percentage evaporation of liquid fuel. It is concluded that manifold heating cannot vaporise fuel droplets to a significant extent although evaporation before ignition is critical for operation at peak performance with lean overall mixtures, so keeping carbon monoxide emissions to a minimum. /TRRL/
