Which manufacturer-specified term represents the power of an engine?

The term that represents the power of an engine can include various specifications provided by the manufacturer, each reflecting different measurements of the engine's power output.

Indicated horsepower refers to the total power developed by the engine's combustion process as calculated from the pressure in the cylinders, but it does not account for any losses in the system. Brake horsepower, on the other hand, measures the actual output power available at the crankshaft, accounting for losses due to friction and other factors. Rated horsepower typically refers to the manufacturer's specified power rating under optimal operating conditions, serving as a standard measure for consumers.

Since all these terms convey different aspects of the engine's power capability as defined by the manufacturer, they collectively encompass the various ways power can be understood in the context of engine performance. Thus, it is accurate to say that all these terms represent different measurements of engine power, justifying the choice that includes all of them.
