Two common definitions used today are the imperial horsepower as in "hp" or "bhp" which is about 745.7 watts, and the metric horsepower as in "cv" or "PS" which is approximately 735.5 watts. The electric horsepower "hpE" is exactly 746 watts, while the boiler horsepower is 9809.5 or 9811 watts, depending on the exact year.
Power Legend: U=unlimited time, D=daytime power, N=nighttime power, CH=critical hours power. Class A unless otherwise specified. Omnidirectional antenna unless otherwise specified.
For the purpose of manageability, this list is limited to production cars that have at least 600 kilowatts. Car models with higher-powered variants are listed only in their most powerful incarnation (for example, the Agera RS would be listed in place of the standard Agera, although the Agera makes over 600 kW).
Engine power is the power that an engine can develop. It can be expressed in power units, most commonly kilowatt, metric horsepower (often abbreviated PS), 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 ...
For reference, about 10,000 100-watt lightbulbs or 5,000 computer systems would be needed to draw 1 MW. Also, 1 MW is approximately 1360 horsepower . Modern high-power diesel-electric locomotives typically have a peak power of 3–5 MW, while a typical modern nuclear power plant produces on the order of 500–2000 MW peak output.
The flywheels store energy on the combustion stroke and supply the stored energy to the mechanical load on the other three strokes of the piston. When these engines were designed, technology was less advanced, and manufacturers made all parts very large. A typical 6-horsepower (4.5 kW) engine weighs approximately 1,000 pounds (450 kilograms).
1 PSh = 0.73549875 kW⋅h = 2647.7955 kJ (exactly by definition) The horsepower-hour is still used in the railroad industry when sharing motive power (locomotives). For example, if Railroad A borrows a 2,500 horsepower locomotive from Railroad B and operates it for twelve hours, Railroad A owes a debt of (2,500 hp × 12 h) 30,000 hp⋅h.
They would rev close to 8,000 rpm and could produce 80 hp (60 kW), close to 1 horsepower per pound (0.6 kW/kg) of engine weight. [4] OMC declared chapter 11 bankruptcy in 2000 and its assets were subsequently acquired by Bombardier Recreational Products, which continued to build Evinrude branded outboard motors.
