The power developed by the engine is measured in BHP (Brake Horse Power). It is a measure of how quickly the work can be done for example Moving the vehicle from point A to point B. In other words, it is the amount of power that is delivered at the flywheel of the engine after fuel consumption. Brake Horsepower can be measured on a dynamometer, which acts as a brake, as opposed to horsepower calculated using some arbitrary formula. The power of the engine is measured at several points in the transmission of its power from the generation to its consumption. The power generated during these stages are called by different names, but none is clear indicators for measurement. Power can be measured at the driving wheel with a rolling road or a chassis dynamometer. The power of an engine depends on its Torque and engine speed. The higher the brake horsepower, the more powerful the engine is. 0.986 BHP = 1 PS. Brake Horse Power is the amount of power that is generated in combustion chambers after the loss of power due to gearbox shifts and drivetrains. This is the actual power generated by the engine, and it could be lesser than the original Horsepower generated in the combustion chambers.
