A gasoline engine uses liquid octane and air, both supplied at P0, T0, in a stoichiometric ratio. The products (complete combustion) flow out of the exhaust valve at 1100 K. Assume that the heat loss carried away by the cooling water, at 100?C, is equal to the work output. Find the efficiency of the engine expressed as (work/lower heating value) and the second-law efficiency
