Question
Each cylinder of a four-cylinder four-stroke petrol engine has a bore diameter of each is 55 mm and
the stroke length for each cylinder piston is 280 mm. During engine testing, the engine runs at 2500
revolutions per minute (rpm) with a pressure-volume indicator diagram showing a mean net area of
6.50 cm² and diagram length of 2.75 cm. For a pressure scale set at 800 kN/m² per cm on the
indicator diagram, calculate the indicated power developed by the engine.
Give your answer in kilowatts (kW) to 2 decimal places.
