2-6. A five-cylinder, 3.5-liter SI engine operates on a four-stroke cycle at 2500 RPM. At this condition, the mechanical efficiency of the engine is 62% and 1000 J of indicated work are produced each cycle in each cylinder. Calculate: (a) Indicated mean effective pressure. [kPa] (b) Brake mean effective pressure. [kPa] (c) Friction mean effective pressure. [kPa] (d) Brake power in kW and hp. (e) Torque. [N-m]
