Name of power which is generated in the cylinder of an IC engine is?

  • A.IHP
  • B.BHP
  • C.FHP
  • D.DBHP

Answer: A

The power developed in the cylinder is the indicated horsepower (IHP).

Indicated horsepower is the power developed by the burning gases on the piston, worked out from the indicator diagram (pressure against volume) of the cylinder, hence the name. It is the highest of the engine's power figures, since nothing has yet been lost to friction.

BHP is what remains at the flywheel after friction, FHP is the power lost to friction (IHP − BHP), and DBHP is the power left at the tractor's drawbar. Mechanical efficiency is BHP/IHP.
