This is the history of internal combustion engine the parts I like
-5th century Roman first did with crankshaft-connecting rod machines to do sawmills
-17th century Christiaan Huygens designed gunpowder to drive water pumps the first rudimentary
internal combustion piston engine
-1780s Alessandro Volta built a toy electric pistol which electric spark explode in a mixture of air and hydrogen which use this pressure to fire cork from the gun
-1794 Robert Street built a compressionless engine
-1807 Swiss engineer Francois Isaac de Rivaz built an internal combustion engine
powered by a hydrogen and oxygen mixture ignited by electric spark.
-1824 Sardi Carnot established the thermodynamic theory for heat engines to
have more temperature difference between the upper and lower working temperature
-1854-57 Eugenio Barsanti and Felice Matteucci patented the first 4- cycle engine
but lost
-1878 Dugald clerk Designed first two-Stroke engine
only till 1878 Ill post more after 1878 cuz after 19th century the innovation bursts off!.
