Brake horsepower (bhp) is the power measured using a brake type (load) dynamometer at a specified location, such as the crankshaft, output shaft of the transmission, rear axle or rear wheels. [ 30 ] In Europe, the DIN 70020 standard tests the engine fitted with all ancillaries and the exhaust system as used in the car.
Brake horsepower per cubic centimeter or (bhp/cc) is a figure of merit that is used to indicate the 'state of tune' of an internal combustion engine. It is defined as the ratio of the engine's net power output to its displacement, the internal size. Power is measured at its rated speed and full throttle.
Engine power is the power that an engine can put out. It can be expressed in power units, most commonly kilowatt, pferdestärke (metric horsepower), or horsepower.In terms of internal combustion engines, the engine power usually describes the rated power, which is a power output that the engine can maintain over a long period of time according to a certain testing method, for example ISO 1585.
The output voltage falls to the cutoff voltage when the battery becomes "discharged". The nominal output voltage is always less than the open-circuit voltage produced when the battery is "charged". The temperature of a battery can affect the power it can deliver, where lower temperatures reduce power.
It is typically used for comparing the efficiency of internal combustion engines with a shaft output. It is the rate of fuel consumption divided by the power produced. In traditional units, it measures fuel consumption in pounds per hour divided by the brake horsepower , lb/(hp⋅h); in SI units , this corresponds to the inverse of the units of ...

For electrical motors, a similar kind of information is conveyed by the service factor, which is a multiplier that, when applied to the rated output power, gives the power level a motor can sustain for shorter periods of time. The service factor is typically in the 1.15-1.4 range, with the figure being lower for higher-power motors.
