Engine power is the product of torque and angular velocity of the crankshaft. Learn how to calculate engine power in different units, such as kilowatt, pferdestärke and horsepower, and see a graph of a diesel engine's power curve.
Horsepower is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. It was originally based on the power of draft horses and later standardized by James Watt in 1782. Learn how to calculate horsepower and compare different types and standards of horsepower.
A diesel generator is a device that converts diesel fuel into electrical energy using a diesel engine and an electric generator. Learn about the different sizes, applications, and modes of diesel generators, as well as their advantages and disadvantages.
Learn how to calculate the torque constant and the velocity constant of electrical motors using formulas and examples. The torque constant is the torque per ampere and the velocity constant is the speed per volt or radian per volt second.
Power density is the amount of power per unit volume, a critical parameter for evaluating devices, systems, and materials based on their spatial energy distribution. Learn how power density is derived, applied, and optimized in various fields, such as energy storage, conversion, and propulsion.
A 2.8L diesel engine was developed by Navistar/International from an inline-four Land Rover Defender diesel 2.5L engine, with 130 hp (97 kW) (waste gate) or 133 hp (99 kW) (VNT). A 3.0L displacement version, with common-rail fuel injection, four-valve-per-cylinder heads, and 160 hp (119 kW) (wastegate turbo), is the electronic version of the ...
Learn how to calculate power-to-weight ratio for engines and vehicles, and see examples of different types of powerplants and their performance. Power-to-weight ratio is a measurement of actual performance of any engine or power source, and is equal to thrust per unit mass multiplied by the velocity of any vehicle.
Learn about the concept of power in physics, how it is measured in watts and other units, and how it relates to work, energy, and force. Explore the different types of power in mechanical, electrical, and fluid systems, and their applications and examples.
