Prior to the 1972 model year, American automakers rated and advertised their engines in brake horsepower, bhp, which was a version of brake horsepower called SAE gross horsepower because it was measured according to Society of Automotive Engineers (SAE) standards (J245 and J1995) that call for a stock test engine without accessories (such as ...
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.
Brake-specific fuel consumption (BSFC) is a measure of the fuel efficiency of any prime mover that burns fuel and produces rotational, or shaft power. It is typically used for comparing the efficiency of internal combustion engines with a shaft output.
The Prony brake is a simple device invented by Gaspard de Prony in 1821 to measure the torque produced by an engine. The term "brake horsepower" is one measurement of power derived from this method of measuring torque. (Power is calculated by multiplying torque by rotational speed.) [1]
The clutch is a multi-plate carbon design with a diameter of less than 100 mm (3.9 in), and weight of less than 1 kg (2.2 lb), capable of handling up to 540 kW (720 hp). [34] The cars use seamless shift transmissions , which allow almost instantaneous changing of gears with minimum loss of drive and a shift times of 2–3 ms . [ 35 ]
In this context, power density is commonly defined as power per swept volume or brake horsepower per cubic centimeter. This measure is derived from the internal capacity of the engine, providing insight into its power output relative to its internal volume rather than its external size.
Between 1995 and 2000, cars using this 3.0 L engine formula, imposed by the FIA, produced a constant power range (depending on engine type and tuning), varying between 600 hp and 815 hp. Most Formula One cars during the 1997 season comfortably produced a consistent power output of between 665–760 hp (495.9–566.7 kW), depending on whether a ...
It describes the efficiency of an engine in terms of the brake horsepower it outputs relative to its displacement. The measure enables the comparison of differently sized engines, and is usually expressed as kilowatts or horsepower per litre or per cubic inch. [1]
