Question:

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.
