Example of a multi-component fuel is a gas that contains H2, CO, CH4, CO2 and N2 etc.
Yes we can but this will produce heavy knocking and its not good for engine as well
Thanks Adnan. Can you make it clear more? How does knock occur?
I have examined both turbulent and laminar premixed flames of H2 + CH4 + O2 + N2 in a constant volume chamber ignited with a spark. The flames propagated like those of homogenous mixtures. Different flame propagation of the component gases was not evident. The effect of the different component is seen in the global flame properties in the form or increase or decrease of the properties due to the concentrations of the components. For instance, increasing H2 content to some extent in that mixture would increase the burning velocity and decrease the markstein number. Although CH4 does not react with H2, they are not oxidized independently. increase in H2 concentration increases the rate of consumption of CH4 by by increasing the pool of OH and H radicals in the flame. Hence, one would not see different flame propagations due to the different components because they "burn together".
