Horse Power question

[ryan_pogi]

a read & hear a lot of different types of HP.
there's this WHP, and there's this BHP.
ano-ano pa ba mga HP jan sa motoring industries, at ano difference ng bawat isa?

thanx.

HP is how the manufacturers refer to the actual BHP (brake horsepower).

Brake horsepower aka HP is measured at the crank with no additional strain (AC belts, etc.) on the powertrains. While WHP is measured at the wheels with all the additional powertrain components(using dynomometer).

HP Yung printer ng nanay ko :D (sorry, di ko matiis hehe )

[ssaloon]

HP din hilig ni pajerokid (Hanky Panky) hehehe joke lang! :D

meron yung gumagamit ng "PS" sa power rating ng engine ... ano yung PS? ano conversion sa kW or Hp?

[yebo]

ps is another term for SHP, or shaft horsepower. that is the power available at the output shaft of a motor or engine (after the flywheel). so in the car engine that is the power available between the engine and the transmission. most of the time expressed in horsepower.

ah ok ... nakakalito kasi nababasa ko parang ganito "Power: 135 PS" ... parang unit of power ang PS, like kW or Hp ... siguro hindi english yung origin ng PS ... baka french, german, or italian kaya ... thanks

[boybi]

unit of power din ang PS, pero mas maliit ng konti lang kesa sa HP.

[mbt]

for all practical purposes, 1 PS is equal to 1 HP... sobrang liit lang ng difference

manufacturers measure horsepower at the crankshaft of the engine. however, keep in mind that there are losses incurred as the power is transmitted through the transmission and drivetrain (the drivetrain, with its numerous parts, is not 100% efficient). thus, power at the wheels ("wheel horsepower") will always be lower than the published crankshaft HP. keep in mind also, that ultimately, it is wheel horsepower that matters since it is the measure of how much power is actually making it to the ground.

the drivetrain losses total about 15%-25%... thus, a 160 hp Civic SiR is actually putting only about 130-140 hp to the front wheels

1PS is = .99HP, sobrang liit nga :lol: And sa Japan yata usually ginagamit ang PS.

PS = "PferdeStarke" the german word for horse power

salamat clark kent! exactly the answer i'm looking for

pero tignan nyo website ng BMW ... Hp ang ginagamit ... sino kaya ang nagpa-uso ng PS na yan? pampagulo eh ... akala ko meron nang international agreement na mag-shift na sa SI units pero wala rin, kanya-kanyang diskarte pa rin

[Karding]

HP ang gamit ng BMW US website, pero BMW German website uses kWand or (PS).

as outlined here: http://www.bmw.com/generic/de/de/pro..._pricelist.pdf

BMW Z4 Roadster 2.5i
Nennleistung: kW 141 / 192 (PS)


Good article about HP,BHP,PS etc.
http://www.wikipedia.org/wiki/Horsepower

The horsepower (hp) is the name of several non-metric units of power. In scientific discourse the horsepower is rarely used due to the various definitions and the existence of an SI unit for power, the watt (W). However, the idea of horsepower persists as a handy term in many languages, particularly in the automotive industry for listing the maximum power of internal-combustion engines.

good info, karding! malinaw na ngayon na 1PS = 0.98632Hp

kinyo,
yep naalala ko yun noon sa isang episode ng Auto extreme hehe. I read somewhere na madaya yang PS eh... some manufacturers use it para magmukhang mataas yung rating hehe

Marami kasing measurement standards ng HP. Meron Deutsche Industrie Norm (DIN) (Literal Translation: German Industry Standard). This is used mostly in Europe. Meron din Society of American Engineers (SAE) used in America. Tapos dito sa atin yung Japanese Standard (forgot the exact name). kW i think is mostly for Australia and New Zealand.

DIN Standards daw are the most conservative while the Jap standard yung least conservative. The article that I read (forgot where I read it) mentioned that 100 SAE Hp is equivalent to about 96-98 DIN PS and around 107 Japanese Horsepower.
