BRAKE HORSEPOWER Meaning and
Definition
-
Brake horsepower (bhp) is a term commonly used in the field of automotive engineering to measure the power output of an engine. It is defined as the amount of power that an engine can deliver at its output shaft, without taking into consideration any losses caused by accessories or other factors.
Specifically, brake horsepower refers to the power output of an engine determined by a dynamometer. A dynamometer is a device that measures the torque and rotational speed of the engine, from which the power output can be calculated. It represents the usable power available to propel a vehicle or perform work.
The term "brake" in brake horsepower originates from early testing methods where engines were typically coupled to a braking system. The brake would absorb the power generated by the engine and convert it into heat. This allowed for accurate measurement of the power output.
Brake horsepower is often used as a standard unit for comparing the performance of different engines. It provides a measure of the engine's power without taking into account any mechanical losses, therefore allowing for easier comparison between different engines or vehicles.
Overall, brake horsepower serves as a crucial indicator of an engine's capability and is widely utilized in the automotive industry as a benchmark for assessing performance and efficiency.

Etymology of BRAKE HORSEPOWER
The term "brake horsepower" (bhp) originates from the early days of steam engines when engineers used a device called a "brake" to measure an engine's power output. The brake was essentially a mechanism that applied resistance to the rotating output shaft of an engine, causing it to slow down or stop. This resistance allowed engineers to measure the amount of power the engine produced.
The unit "horsepower" itself was first developed by the engineer James Watt in the 18th century as a means to compare the power output of steam engines to that of horses, which were commonly used as a power source at the time. Watt estimated that a strong horse could do approximately 550 foot-pounds of work per second, and he used this as the basis for defining one horsepower.
