diesel-electric

the term is a modern compound adjective formed in the early 20th century, combining the name of rudolf diesel with the word 'electric'. diesel's invention of the high-compression internal combustion engine provided a reliable and efficient power source. when this diesel engine is coupled with an electric generator and motors to create a hybrid drive system, the resulting technology is logically named 'diesel-electric'. this nomenclature directly specifies the two core components of the system: the diesel prime mover and the electrical transmission, distinguishing it from purely mechanical or purely electric systems.
