LENOIR
(Belgium)
Jean Joseph Ethiene Lenoir was the first to apply Beau de Rochas's theories in 1842, although on a gas engine with little compression.
-Later, the first successful engine with the 4-stroke cycle was made by Nikolas August Otto. In 1860 and years later, Benz made the first vehicle powered by these engines.
-From then until today, the 4-stroke or Beau de Rochas cycle is the one that continues to be applied in aviation piston engines.
