Determine the brake mean effective pressure, Mechanical Engineering

Assignment Help:

A 4 cylinder petrol engine operates on the 4-stroke cycle. The bore of each cylinder is 70mm and stroke 100mm. The clearance volume per cylinder is 60cm3. At a speed of 4000rpm, the fuel consumption is 20 kg /h and the torque talk developed is 150 Nm. Determine

(i) The brake mean effective pressure.

(ii) The brake power

(iii) The brake thermal efficiency if calorific value of the fuel is 44000 kJ/kg.

(iv) The relative efficiency on a brake power basis assuming the engine works on constant volume cycle.
