Shaft horsepower (shp) is the power delivered to a propeller shaft, a turbine shaft, or to an output shaft of an automotive transmission. [32] Shaft horsepower is a common rating for turboshaft and turboprop engines, industrial turbines, and some marine applications. Equivalent shaft horsepower (eshp) is sometimes used to rate turboprop engines ...
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.
In this case, unless external limitations are applied, the maximum torque is achieved at low RPM. For example, the AC motor found in the Tesla Roadster (2008) produces near constant maximum torque from 0 to about 6000 RPM, while maximum power occurs at about 10000 RPM, long after torque begins to drop off. The Roadster's redline is 14000 RPM.
Torque forms part of the basic specification of an engine: the power output of an engine is expressed as its torque multiplied by the angular speed of the drive shaft. Internal-combustion engines produce useful torque only over a limited range of rotational speeds (typically from around 1,000–6,000 rpm for a small car).
Engine Horsepower Torque Carburetor Compression ratio Bore & stroke VIN code 250-1V I-6: 155 hp (116 kW) @ 4000 rpm: 240 lb⋅ft (325 N⋅m) @ 1600 rpm
The L5P Duramax received an increase in horsepower and torque for the 2024 model year; 470 hp (350 kW) at 2,800 rpm and 975 lb⋅ft (1,322 N⋅m) at 1,600 rpm. Design specification performance can exceed 550 bhp (410 kW) at 3050 rpm and 1,050 lb⋅ft (1,424 N⋅m) at 1975 rpm. [12]
The torque on shaft is 0.0053 N⋅m at 2 A because of the assumed radius of the rotor (exactly 1 m). Assuming a different radius would change the linear K v {\displaystyle K_{\text{v}}} but would not change the final torque result.
The DOHC ECC 2.0 produces 150 hp (112 kW) SAE at 6500 rpm with 139 lb⋅ft (188 N⋅m) of torque at 4800 rpm. It has a cast iron engine block and aluminum DOHC cylinder head. It uses Sequential fuel injection , has 4 valves per cylinder with roller rocker arms and features fracture-split forged powder metal connecting rods , a one-piece cast ...
