Difference between horsepower and bhp

Except for electrical machines such as motorsyou may frequently hear the word horsepower HP if you are a car enthusiast, related to engines or general vehicles and mostly from the mechanics in the machine shops.

What is bhp, and how does it differ from hp? Horsepower and brake horsepower are both intended to measure the power of an engine. However, the way in which the figures are calculated is different, and this results in differing numbers. An engine is measured for horsepower with some pieces of the system missing, while brake horsepower is measured with every component in place. As a result, brake horsepower measurements include more frictional losses, which results in a lower figure.

Although the automotive industry has progressed quite a bit, certain things remain unchanged. Just as important, if not more, than the list of features and amenities. However, there is a sense of ambiguity when discussing output. Is it engine horsepower hp or brake horsepower bhp? What about wheel horsepower WHP? What's the difference between horsepower and torque? Are they all the same? Mind you, these people are not just your average Joe or Joanne but sometimes include actual car folks. Horsepower is the unit measurement of power. Or, in other words, how much work the engine is capable of doing. Measuring horsepower is most commonly done via a dynamometer , with mathematics taking care of the second half. Brake horsepower bhp is very similar to hp. When calculating bhp, a brake-type dynamometer factors in the frictional losses from auxiliary engine pumps.

Rather, a device called a dynamometer more commonly known as a dyno is used to calculate its force. The difference between the two is small on a basis. What's the difference between horsepower and torque?

While hp does not take into account frictional losses in power from an engine, brake horsepower does — meaning hp is always higher than bhp. The difference between the two is small on a basis. For example, a car with hp would then have bhp.

Manufacturers typically now publish power figures in horsepower, though old habits die hard — with a lot of traditional car magazines still using a conversion to bhp as the blanket measurement. Horsepower is actually a completely made-up measurement. Back in the late s, steam engine pioneer James Watt wanted to compare the effectiveness of his engines against the horse that previously did their work.

Difference between horsepower and bhp

Power is defined as the capacity to do work. HP stands for horsepower and is a measure of the power of an engine, while BHP stands for brake horsepower and is a measure of the power of an engine at the output shaft. BHP is considered a more accurate measure of engine power, as it considers losses due to friction and other factors. The horsepower or hp is a unit of measurement of the output power of a mechanical or electrical system. It has various types, such as metric hp and automatic hp. The brake horsepower or bhp is the engine power of a mechanical or electrical system. It also considers the various losses due to friction in the engine.

I agree with both Dave and Chris…. I thought car manufacturers just wrote whatever rubbish came into their minds in their brochures just to sell stock. And Chris, that is NOT a maybe.

Realize that on a broader scale, horsepower is just a measurement interpreted differently across different parts of the world. If the force and distance are in the same direction, the angle is 0 degrees, which has a sine of one. Rather, a device called a dynamometer more commonly known as a dyno is used to calculate its force. Latest posts by Mabelle see all. Food energy used to be measured in Calories Cal and some countries still use those units. In addition, the machine efficiency will be maximum when the copper losses are equal to the constant losses.

Vivek Shingada. Automakers sure do have a bee in their bonnet when it comes to horsepower figures.

In the English Imperial system, force and distance actually displacement are at a maximum when they are in the same direction. Food energy used to be measured in Calories Cal and some countries still use those units. On the other hand, Brake Horsepower measures the HP of an engine without considering the loss in power that is caused by some parts of the engine, like the generator, gearbox, water pump and other auxiliary parts. HP is actually the same as BHP. Power can be measured in various units, but most commonly kilowatts and horsepower. Yes, but you will need to modify the engine. I take this answer to be more understandable for me. For anyone wondering about torque versus power, power is generated by a torque rotating at some angular velocity rotational speed and is equivalent to a force moving at some linear speed.
