The total hydrocarbon emissions and the distribution of hydrocarbon species from the emissions of two different piston and cylinder liner designs; 1 reduced top land height, 2 smoother cylinder bore, were compared with a standard production Rover K16 spark ignited engine. Reductions in total HC emissions were achieved for both designs. The variations between the relative quantities of a selection of the most significant species were investigated for each design, considerable differences were observed between these design changes.
