Experimental data are presented of the knock and combustion characteristics of a wide range of fuel mixtures of CO, H2 and CH4 while using a variable compression ratio engine. A predictive model was employed for predicting such characteristics where the oxidation reactions of mixtures of H2, CO, and CH4 were simulated using detailed chemical kinetics. Predicted results were validated against those determined experimentally and showed good agreement for a wide range of fuel compositions and operating conditions. However, it was noted that the predicted knock limited equivalence ratios for dry CO-air operation, in comparison to the other fuel applications, tended to display deviation from the experimentally established values. The reasons for this tendency are discussed and measures to permit the prediction of such a behavior are presented.
