Friction Horse Power
The power consumed within the engine from friction between its parts.
The difference between indicated power and the brake power output of an engine is the friction power.
Frictional losses are ultimately dissipated to the cooling system and so this influences the required cooling capacity.
The bsfc rises with an increase in speed. Thus, the level of friction decides the maximum output of the engine which can be obtained economically.
