Specific fuel consumption of a four-stroke internal combustion engine at a given rotational speed is 0.322 kg/kW-h value is minimum. Spindle power at this rotation rate is 123 kW, volumetric efficiency is 95% and air-fuel rate is 15. The number of rotations of this engine is calculated by subtracting 1.5 from the number of rotations giving the minimum specific fuel consumption. time, spindle power 162 kW, specific fuel consumption 0.394 kg/kW-h and volumetric efficiency 85%. a) Calculate the air-fuel ratio in this case. and By what percent has the efficiency of the engine changed?
