The efficiency is the amount of work output divided by the amount of work input. The work output is given as 3400 J/s. The work input is given as 10200 J/s. The efficiency is 3400/10200 = 0.33 or 33%.

Carnot efficiency is defined as (T1 -T2)/T1 x 100 where T1 is the temperature of the burning gasoline and T2 is the temperature of the air; therefore, the Carnot efficiency is (2600K - 304K) /2600K x 100 = 88.3%.
