A four-stroke cycle, four-cylinder CI engine, operating at 3000 RPM, produces 48 kW of brake power. Volumetric efficiency is 0.92 and air–fuel ratio AF=21:1

Calculate:

(a) Rate of air flow into engine. [kg/sec]

(b) Brake specific fuel consumption. [gm/kW-hr]

(c) Mass rate of exhaust flow. [kg/hr]

(d) Brake output per displacement. [kW/L]
