Normal Rated Power

 

the power developed by an engine over the greater part of its regular operation. It is defined as the average power developed under specific conditions during extended operation and is a function of the load on the engine or on the unit in which the engine is installed. For example, the normal rated power of the main engine of an ocean liner is close to the nominal (calculated) power; the normal rated power of a diesel switching locomotive is substantially lower than the nominal power. Different engines with different performance characteristics are needed to handle different types of loads. Efficiency of power production at an engine’s normal rated power is required for the most efficient overall operation of the engine.
