Pabbi átti neflilega einu sinni svona 2000 árgerð (WRX) og það voru alveg ótrúleg ár í minni æsku. Hann seldi hann fyrir u.þ.b. ári - eins og hálfs árs.
The term “brake” refers to the use of a band brake to measure torque during the test (which is multiplied by the engine speed in revs/sec and the circumference of the band to give the power).
Baseline is that hp and bhp are the same thing – horsepower measured at the engine flywheel.
A scottish man named Watt figured that a horse could do 746 watts of work.Veit ekki hvaðan þú hefur þessar heimildir um þennan mun en ég held að það sé einhver misskilningur í gangi með þær.
Germans estimated that their horses could only do 736 watts of work and they called their measurement Pferdestaerke or PS (hp).
Conversion factor is approx 0.9866 PS = 1 BHP (fengið út með því að deila 736/746=0.9866) ergo, the 250 BHP has been translated to 247 PI (hp).
Brake horsepower (bhp) is the measure of an engine's horsepower without the loss in power caused by the gearbox, generator, differential, water pump and other auxiliaries. Thus the prefix “brake” refers to where the power is measured: at the engine's output shaft, as on an engine dynamometer.
The term “brake” refers to the original use of a band brake to measure torque during the test (which is multiplied by the engine speed in revs/sec and 2*pi radians/rev to give power, which is then converted to horsepower).
HP is the “general” term. Indicated horse power is the theoretical horse power that an engine can produce. Brake horse power equals the Theoretical HP minus the internal friction (power loss).So. BHP is really the HP available at the crank.
Wheel“ HP, or RWHP (rear-wheel drive HP), or FWHP (front-wheel drive HP), etc. Is measured when a car is put on a rolling dyno, and the amount of power that the car puts down on the pavement (or at the driven wheels) is measured. This is more of a true measurement of how the overall car will perform.
BHP, or ”brake" HP, is measured when the engine alone is put on a special dyno to measure what the engine alone puts out. This is the number that manufacturers give for the car's power. The is the 250 HP that the Renesis is supposed to have.
The Wheel HP number is normally around 20% less than the Brake HP, because the transmission and other drivetrain components (and sometimes the installed exhaust and intake components) eat up some of the power.
Brake horsepower (bhp) is the measure of an engine's horsepower without the loss in power caused by the gearbox, generator, differential, water pump and other auxiliaries. Thus the prefix “brake” refers to where the power is measured: at the engine's output shaft, as on an engine dynamometer. The actual horsepower delivered to the driving wheels is less. An engine would have to be retested to obtain a rating in another system.
