Quick Answer

Rudolf Diesel patented the diesel engine in 1893 and built a working prototype in 1897.

The Full Story

German engineer Rudolf Diesel received a patent for his compression-ignition engine on 23 February 1893 and demonstrated a successful prototype at a factory in Augsburg on 10 August 1897. Unlike gasoline engines, the diesel engine ignites fuel through high compression rather than a spark plug, achieving higher thermal efficiency. Diesel originally envisioned the engine running on peanut oil, foreseeing biofuels by over a century. He disappeared from a ship crossing the English Channel on 29 September 1913; his death remains mysterious.

Key Facts

1.Diesel engines are about 20–35 % more fuel-efficient than gasoline engines.
2.About 70 % of global shipping fuel is diesel.
3.Diesel's original 1897 prototype achieved about 26 % thermal efficiency — remarkable for the era.
