Besides high torque and efficiency, what contributed to the engine's operational safety and industrial acceptance?

Answer

The lower flammability risk of diesel fuel compared to gasoline.

A key factor often overlooked is the lower flammability risk associated with diesel fuel when compared directly to gasoline, which added an extra layer of operational safety, particularly in confined environments like mines or engine rooms.
