The effect of hydrogen addition to fuel on ignition delay and combustion duration in spark ignition engines has been experimentally investigated. The mass fraction burned as a function of crankangle was determined by incorporating calibrated cylinder pressure traces into a two-zone thermodynamic analysis. Two different types of engines were employed: a 4-cylinder, 4-stroke passenger car engine and a single cylinder, 2-stroke shnurle-type engine. The results are presented together with processed results of Rauckis and and McLean. For combustion duration, a very good correlation between the 'eddy burning' model and the experimental observations has been obtained. However, for ignition delay the theory underestimated the pronounced effect of hydrogen addition.
