For example, an unloaded motor of = 5,700 rpm/V supplied with 11.1 V will run at a nominal speed of 63,270 rpm (= 5,700 rpm/V × 11.1 V). The motor may not reach this theoretical speed because there are non-linear mechanical losses.
An electric supercharger is a specific type of supercharger for internal combustion engines that uses an electrically powered forced-air system that contains an electric motor to pressurize the intake air. By pressurizing the air available to the engine intake system, the air becomes more dense, and is matched with more fuel, producing the ...
As realized in the 2007 Volt concept, the initial E-Flex design includes an electric traction motor with peak power and torque outputs of 120 kW (160 hp) and 320 N⋅m (240 lbf⋅ft), a 1 L 3-cylinder gasoline engine coupled to a generator with an output of 53 kW (71 hp), and a 16 kWh (58 MJ) lithium-ion battery energy storage system.
The road-going engine is rated at 663 PS (488 kW; 654 hp) at 11,500 rpm, with a max torque figure of 467 N⋅m (344 lbf⋅ft) at 9,000 rpm, [1] making it the highest revving road car engine ever produced. [2] The engine is also more powerful than the 6.1 L (6,064 cc) S70/2 V12 engine used in the McLaren F1.
A fractional-horsepower motor (FHP) is an electric motor with a rated output power of less than one horsepower (745.7 W) (the term 'fractional' indicates less than one unit). There is no defined minimum output, however, it is generally accepted that a motor with a frame size of less than 35mm square can be referred to as a 'micro-motor'.
V engine in V8, V12 or V16 configurations: Displacement: 942 cu in (15.4 L) per cylinder: Cylinder bore: 10" (254 mm) Piston stroke: 12" (305 mm) Valvetrain: 4 valves per cylinder head: RPM range; Max. engine speed: 750-850rpm: Combustion; Fuel type: Diesel: Cooling system: Liquid cooled: Output; Power output: 63.3 hp (47 kW) to 213.75 hp (159 ...
While engines and motors have a large range of operating speeds, the power band is usually a much smaller range of engine speed, only half or less of the total engine speed range [1] (electric motors are an exception—see the section on electric motors below). Specifically, power band is the range of RPM around peak power output.
The inline six-cylinder 71 series engine was introduced as the initial flagship product of the Detroit Diesel Engine Division of General Motors in 1938.. This engine was in high demand during WWII, necessitating a dramatic increase in output: about 57,000 6-71s were used on American landing craft, including 19,000 on LCVPs, about 8,000 on LCM Mk 3, and about 9,000 in quads on LCIs; and 39,000 ...
