The first carburetor was invented by Samuel Morey in 1826. The first person to patent a carburetor for use in a petroleum engine was Siegfried Marcus with his 6 July 1872 patent for a device which mixes fuel with air.
András Mechwart
Mechwart get in contact with János Csonka as well. By the buying of the factory in Leobersdorf they had a lot of finished, but unfunctioning engines. Mechwart left the repairing of these engines to Donát Bánki and to the leader of the trainning workshop of the Technical University of Budapest, János Csonka who was already well-known because of his engine constructions. Their cooperation consisted beside the repairing of these unfunctioning engines, also the gas- and petroleum engines between 1889 and 1896. As a result of their common improvements the carburetor was born in 1893.
