A six-cylinder, 4-stroke petrol engine has a swept volume of 3.0 litres with a compression ratio of 9.5. Brake output torque is 205 N-m at 3600 r.p.m. Air enters at 85 N/m2 and 600C. The mechanical efficiency of the engine is 85% and air-fuel ratio is 15 : 1. The heating value of fuel is 44,000 kJ/kg and the combustion efficiency is 97%. Calculate:
- Rate of fuel flow
- Brake thermal efficiency
- Indicated thermal efficiency
- Volumetric efficiency
- Brake specific fuel consumption
