Problem 5 on IC engine, Engine capacity or Cubic capacity, four stroke engine

Single cylinder , 4 stroke gas fuelled engine delivers a brake Power of 20 kW at 6000 rpm. air-gas ratio 8:1 calorific value of fuel = 11MJ/m^3 compression ratio = 8:1 volumetric efficiency 70% indicated thermal efficiency 33% mechanical efficiency 90% Calculate engine capacity of the engine.
