A four-cylinder racing engine of capacity 2.495 HIM has a bore of 94 mm and a compression ratio of 12/1. When tested against a dynamometer with a torque arm of 0 461 m a maximum load of 622 N was obtained at 5000 rev;min, and at the peak speed of 6750 rev/min the load was 547 N. The minimum fuel consumption was 17.2 ml/s at a speed of 5000 rev/min. the specific grasity of the fuel being 0.735. and 44 209 kJ/kg. Calculate the maximum brnep, the minimum bp, the minimum specific fuel consumption. and the maximum brake thermal efficiency at maximum torque. and compare this latter answer with the air standard efficiency.
