Why does the fuel consumption of the diesel engine ...

All Answers ( 18) For constant speed for stroke diesel engines, general tendency is that at 80% of the full load operation, specific fuel consumption (fuel consumption per unit brake power) decreases at 80% of the load, and beyond that load, it increases. This is due to increase of fuel conversion efficiency up to 80% of the load,...
