ed84c Posted January 15, 2005 Share Posted January 15, 2005 what does the Break mean in BHP? Link to comment Share on other sites More sharing options...
5614 Posted January 15, 2005 Share Posted January 15, 2005 BHP generaly means breaking horse power, what do you mean what does "break" mean? it means the breaking as in deceleration. Link to comment Share on other sites More sharing options...
ed84c Posted January 15, 2005 Author Share Posted January 15, 2005 I ve always understood it as 'Break Horse Power' However if HP is a measurement of the engines power, what does it have to do with breaking? Link to comment Share on other sites More sharing options...
5614 Posted January 15, 2005 Share Posted January 15, 2005 horse power is acceleration power break horse power is the opposite. HP and BHP are measure in the same "HP" but are different, if ya see what i mean. Link to comment Share on other sites More sharing options...
ed84c Posted January 15, 2005 Author Share Posted January 15, 2005 so essentially they are the same, a bit like how a in F=ma, means change in acceleration rather than just acceleration. Link to comment Share on other sites More sharing options...
5614 Posted January 15, 2005 Share Posted January 15, 2005 kinda, HP is acceleration BHP is deceleration. Link to comment Share on other sites More sharing options...
ed84c Posted January 15, 2005 Author Share Posted January 15, 2005 but a car has the same BHP and Hp? Link to comment Share on other sites More sharing options...
5614 Posted January 15, 2005 Share Posted January 15, 2005 it does? are you sure? does that ALWAYs apply? or is it just a common trend? maybe i was talking crap, i dont think so though! Link to comment Share on other sites More sharing options...
5614 Posted January 15, 2005 Share Posted January 15, 2005 oh bollocks,,, i WAS talking totaly and utter crap! Brake horsepower. A measurement standard used by manufacturers to help consumers compare engines. NOTE: BHP is measured at the maximum operating RPM of the engine, which may not be the RPM level at which your engine will provide maximum life and consistent performance. rpm = revolutions per minute Link to comment Share on other sites More sharing options...
5614 Posted January 15, 2005 Share Posted January 15, 2005 horsepower: a unit of power equal to 746 watts Link to comment Share on other sites More sharing options...
5614 Posted January 15, 2005 Share Posted January 15, 2005 so what DOES "brake" stand for in BHP? BHP is to do with engine power, nothing to do with breaking or braking. Link to comment Share on other sites More sharing options...
Klaynos Posted January 15, 2005 Share Posted January 15, 2005 "Brake horse power, the net effective power of a prime mover, as a steam engine, water wheel, etc., in horse powers, as shown by a friction brake" See: http://dictionary.reference.com/search?q=brake%20horse%20power Also: http://en.wikipedia.org/wiki/Bhp#bhp (Note: indication of reality, but worth reading) Seems to be a measure of power which is actually measure instead of calculated and therefore takes resistance inside the engine into account... Therefore the break is refering to the internal resistance of the engin, it seems. Link to comment Share on other sites More sharing options...
5614 Posted January 15, 2005 Share Posted January 15, 2005 It indicates the brake[/u'], the device for measuring the true power of the engine. this doesnt sound like the normal brakes on a car, so i think the original question still stands. [edit] ok that last line of klaynos's post was not there a second ago! [edit2] its brake not break Link to comment Share on other sites More sharing options...
ed84c Posted January 15, 2005 Author Share Posted January 15, 2005 I thought dictionary.com is not a technical resource?........ Link to comment Share on other sites More sharing options...
5614 Posted January 15, 2005 Share Posted January 15, 2005 hey... you are the one who asked for a definition! Link to comment Share on other sites More sharing options...
Klaynos Posted January 15, 2005 Share Posted January 15, 2005 I thought dictionary.com is not a technical resource?........ It's not but it's the best I could do and still be fundementally lazy bhp is not a commonly used physical description of a power source, and it is therefore quite hard to find a technical resource which will refer to it with a definition :s Link to comment Share on other sites More sharing options...
Crash Posted January 16, 2005 Share Posted January 16, 2005 an now the new dragesters use "ponyshits" or PS a slang for a fraction (i cant remember what) of a Horsepower Link to comment Share on other sites More sharing options...
ed84c Posted January 16, 2005 Author Share Posted January 16, 2005 no iwas joking, as 5614 pointed out Sayos sig earlier yesterday. Link to comment Share on other sites More sharing options...
The Rebel Posted January 17, 2005 Share Posted January 17, 2005 My understanding of it is that horsepower is all about work, and how much energy is used for a particular job, e.g. torqueing something up, or dragging something, etc. It's equivalent to force x distance. Brake Horse Power is a measure of capability. I think its based on the amount of horses need to do the same work as the engine in the same time. To measure BHP we basically take an engine up to full speed, add some resistance (thus lowering the speed of the engine by torque), and equate the energy the engine is giving off by subtracting the work used on the load to the measurement at the opposite end. One example would be to wrap a rope around a pulley being driven by an engine. One end would be trying to lift a weight the other would be measuring the weight. The difference between the two shows the work done by the energy. Another is to have a clamp on a pulley driven by an engine under test, which is connected to some weights, the height the weights travel at a certain engine speed ( a bit like the biting point in the car, when the car starts to lift from the front), gives a BHP value. Today they use a dynamo either directly connected via a flywheel or using "rolling roads" and add in transmission losses, to find the power given by the engine in BHP.
