1. A flexible fuel vehicle operates with a mixture of 35% isooctane and 65% methanol, by volume. If the combustion is to be stoichiometric, what should the mass air--fuel ratio be?

2. If an dragster fuel tank contains a mixture of 70% octane and 30% nitromethane, by volume, what should the mass air--fuel ratio be to run rich at ???? = 1.24?

Answer rating: 100% (QA)

To determine the mass airfuel ratio for stoichiometric combustion and for running rich we need to calculate the mass of air and fuel in each scenario ... View the full answer
