Bhp what is it mean

The metric equivalent of a single horsepower, referred to as 1 PS, equals 4, kilogram-metres per minute, which rounds to 32, foot-pounds per minute, or 0. The horsepower rating of an engine is usually measured on a dynamometer, which is a form of mechanical brake used to apply variable loads to a running engine so that torque and power may be calculated at different engine revs — hence brake horsepower which is always quoted at a given RPM.

UK laws explained. Only engineers tend to talk about indicated horsepower, and then just amongst themselves. However, it is worth noting, that depending on who you speak to, wheel horsepower and BHP are often used interchangeably — again adding to the confusion. Skip to Content Skip to Footer.

To use fuel an engine needs 15 times more air than fuel present, cc measurements related to how much air an engine can take in. The bigger the engine size the larger the quantity of air intake and so the more fuel can be burnt.

If more fuel is burnt, then more power can be generated. This would lead you to believe that again, the larger the number the more powerful the engine, but advances in technology now mean this is not always true.

So to keep it simple if you want more speed and acceleration prefer a car with good BHP and if want a vehicle to haul stuff around at minimum performance problems you should consider more torque.

Energy Energy is the ability to do work. Power An engine being tested for power Power is the rate of using energy. Vector and Scalar Forces A little out of the topic thing that we need to cover which will make understanding power and energy even easier. This means BHP is scalar while torque is a vector quantity. What is Torque? Torque The measure of a force which rotates about an axis is known as torque.
