There are many different standards and types of horsepower. 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 ...
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 ...
Torque measurement is somewhat complicated since there are two machines in tandem - an inline torque transducer is the preferred method of torque measurement in this case. An eddy-current or waterbrake dynamometer, with electronic control combined with a variable frequency drive and AC induction motor, is a commonly used configuration of this type.
Boom. Crash! In today's fast-paced world, car crashes feel like simply a fact of life. In 1913, before cars dominated the roads, there were only 1.3 million vehicles registered and 4,200 deaths ...
The terms "active" and "passive" are simple but important terms in the world of automotive safety. "Active safety" is used to refer to technology assisting in the prevention of a crash and "passive safety" to components of the vehicle (primarily airbags, seatbelts and the physical structure of the vehicle) that help to protect occupants during a crash.
Ward, of Parsonstown, Ireland, was thrown out of a motor vehicle and killed. [10] Thirty years later, on September 13, 1899, Henry Bliss became North America's first motor vehicle fatality when hit while stepping off a New York City trolley. The need for a means of analyzing and mitigating the effects of motor vehicle accidents on humans was ...
Speed has dropped out of the equation, and the only variables are the torque and displacement volume. Since the range of maximum brake mean effective pressures for good engine designs is well established, we now have a displacement-independent measure of the torque-producing capacity of an engine design – a specific torque of sorts.
With a governor set to 8% accuracy, the rated power is 21.33 kW (29 bhp; 29 PS) at 3000 min −1, the highest torque is 69.63 N⋅m (51 lbf⋅ft) at 2000 min −1. [4] For other applications, the power and torque output may vary, e.g. On the Beetle produced 41 PS (40 bhp; 30 kW) at 3900 rpm and 88 N⋅m (65 lbf⋅ft) of torque at 2400 rpm.
