What Is the Stoichiometric Air-Fuel Ratio for a Dual Fuel IC Engine?

[ashishbhagwat]

Homework Statement

a mixture of 0.64 x 100 percent iso-octane and {1-0.64} x 100 percent methanol, based on volume, is mixed with air and combusted. Calculate the stoichiometric air fuel ratio. Note: please not this is mixing on a molar basis, not mass basis. It is necessary to perform a complete chemical analysis to solve this problem. Begin by writing the chemical equation for fuel and air= products of combustion, for a dual fuel problem. Then, calc the mass of the fuel and the mass of the air
