A six cylinder 2-stroke diesel engine running at 120 rev/min has a bore of 900mm and a stroke of 1300mm. The brake torque is 700 kNm, the mechanical efficiency is 94% and specific fuel consumption on a brake power basis is 0.24 kg/kWh.
Determine:
(i) The brake power developed,
(ii) The brake thermal efficiency,
(iii) The IMEP.
The heating value of the fuel used is 42 MJ/kg.
