Contents include: the effect of engine variables on hydrocarbon emissions - an investigation with statistical experiment design and fast response FID measurements; effects of gas flow and mixture properties on engine-out HC emissions; a strategy to improve the efficiency of stoichiometric spark ignition engines; analyses of exhaust hydrocarbon compositions and ozone forming potential during cold start; time-resolved, speciated emissions from an SI engine during starting and warm-up; simulation of exhaust unburned hydrocarbons from a sp ignition engine, originating from in-cylinder crevices; effect of fuel preparation on cold-start hydrocarbon emissions from a spark-ignited engine; and effects of mixture preparation on HC emissions of a SI engine operating under steady-state cold conditions.
