No, "Horsepower" was originally defined to compare the output of steam engines with the power of draft horses.
"Brake horsepower" (BHP) is the amount of work generated by a motor without taking into consideration any of the various auxiliary components that may slow down the actual speed of the motor. Sometimes referred to as pure horsepower, brake horsepower is measured within the engine's output shaft.

What is the difference between Shaft horsepower and Brake horsepower?
Shaft horsepower is the power output from an engine after it is put through the gear train and other components that result in a loss of power. It is usually used in respect to aeroplanes and ships though it can be used as the power output from a cars gearbox. Brake horsepower is the power an engine puts out at the crank and is not subject to losses. It is always higher than the true horsepower. The true horsepower or rear wheel horsepower is the power that is actually driving a vehicle foreward and is probably the most important for comparing motor vehicles. Horsepower itself is the imperial unit for power, like the metric systems Watt. 1 hp = 0.75kW
What is better a 500cc engine or 700cc engine?
if same power output, larger engine will be less stressed
What is Prony brake dynamometer?
proney brake dynamometer is a device use to measure engine power
What do you mean by the term mechanical efficiency of an engine?
It is the ratio of indicated power to brake power.
How do you compare a turbo charged engine and a normal engine quantitatively in terms of power output and efficiency?
How many horses, and how much gas mileage...power/effeciency
Why is it called brake horsepower?
Brake horse power is the amount of engine power which makes it to the wheels. This is different from the actual output at the engine.
What is brake thermal efficiency?
The ratio of brake power output to power input
The maximum power output of an engine is usually given in units called?
It's given in the units called: BHP=Brake Horse Power
Is the high output in line six cylinder engine a good engine?
No, Based on power output to displacement, that engine is terrible No, Based on power output to displacement, that engine is terrible No, Based on power output to displacement, that engine is terrible
What is difference indicated power and brake power?
In an engine, indicated power is the power produced in the cylinder and the brake power is the useful power at the output shaft. Brake power is always less than indicative, due to losses by mechanical friction and parasitic loads (oil pump, air conditioner compressor, etc...) The two are related by (mechanical efficiency) = (brake power) / (indicative power)
What is meant by brake horse power in cars?
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. 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).
What is the difference between brake horsepower and horsepower?
The difference between brake horsepower and horsepower or wheel horsepower, they are the same thing, is that brake horse power is the power produced by the crank. The wheel horsepower is the amount of power delivered to the wheels. Brake horsepower refers to the method used to test the engine. A brake is attached to the engine and used to maintain the engine at a constant RPM at full throttle. The delivered power output is then a simple calculation of RPM times torque. Horse power is based on the average amount of work that a horse could do in a day. It is taken to be 746watts. well you guessed it engine output is also specified in kilowatts so divide by 746 and you have horsepower. As stated above it is all the same thing. There is a difference between advertised horsepower and brake horsepower. Advertised horsepower is what a manufacturer will rate its engine/automobile/machine to produce. Brake horsepower is the actual measured horsepower, for example, of a motor on an engine dynamometer.
What is the brake horse power for a peugeot 307cc?
The brake horsepower of the diesel version of the 307 cc is 135, and the 2.0 petrol model is 138 bhp. The diesel model feels more sporty due to the torque delivery, the cc is a heavy car and benefits for the power delivery of the diesel engine/gearbox.
What is brake horsepower?
Brake Horsepower is simply power rated at the output shaft or journalThe term is used in powertrain applications mostly, because moving parts (transmissions etc) use some percentage of output force to operate by demonstrating some element of loss (heat, noise etc) when in operation, its usefull in separating the power output(s) when disclosing them.Abbreviations "BHP"Not to be confused with "Output", or "Horsepower at the Wheels" Brake horse power is the unit of measurement of power. It is the rate at which work is done. It is the most common conversion factor for electrical power. Brake Horse Power is also known a "crank Horse power"This is the measurement in horse power an engine will make while NOT driving any accessories.These accessories include:AlternatorWater pumpBeltsPower steeringACGear boxDifferentialand any other item driven by the engine that it does not need to directly run.The testing is done currently in a way that measures these losses and figures out an Brake Horse Power rating
Will the power brake work just one time if the engine fails?
The power brake reduces the driver's effort to brake by enlisting the engine to boost brake pressure. The Power Brake system is designed in such a way that should the engine fail, the brake will still work one more time.
What is the bhp in marine vessel engine?
The BHP in a marine vessel engine has the meaning of Brake Horse Power. Brake Horse Power is power that is measured in the engine's crankshaft.
