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.
Tax or fiscal horsepower is a non-linear rating of a motor vehicle for tax purposes. [19] Tax horsepower ratings were originally more or less directly related to the size of the engine; but as of 2000, many countries changed over to systems based on CO 2 emissions, so are not directly comparable to older ratings.
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 ...
In the United States, the Office of Vehicle Safety Compliance, a component of the Department of Transportation, is one of the agencies tasked to enforce the Federal Motor Vehicle Safety Standard (FMVSS). [3] Canada has published tire regulations, such as the Motor Vehicle Tire Safety Regulations SOR 95-148. [4] Metric tire code example
The Touareg V6 TSI Hybrid is a prototype hybrid vehicle featuring a 2,995 cc (182.8 cu in) V6 petrol engine with a 'Twin Vortices Series' (TVS) supercharger rated at 333 PS (245 kW; 328 bhp) at 5,500 rpm and 440 N⋅m (325 lbf⋅ft) of torque at 3,000 rpm, an electric motor rated at 52 PS (38 kW; 51 bhp) and 300 N⋅m (220 lbf⋅ft) of torque ...
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.
With power typically being the product of force and speed, a motorcycle's power and torque ratings will be highly indicative of its performance. Reported numbers for power and torque may however vary from one source to another due to inconsistencies in how testing equipment is calibrated, the method of using that equipment, the conditions during the test, and particularly the location that ...
Production vehicles with in-wheel motors include: Lohner–Porsche Chaise, Mixte, and others. Several models based on this design were produced by Lohner and other manufacturers in the early 1900s. [16] [7] Lightyear 0, briefly produced in 2022 using Elaphe In-Wheel Motors [42] before its manufacturer filed for bankruptcy. [43] [44]
