The first effective carburetor unit.

On the 18th of October 1893 Donat Bankee and Yanosh Chonk took out a patent on an atomizing carburetor unit, titled “An Improvement for Petrol Engines”. The concept of this carburetor was the following: if petrol is atomized in the air in particles small enough that leads to its even distribution among the cylinders; vaporization inside cylinders occurs due to the heat produced under compression. Bankee suggested imbibing petrol into the air flow via a dosing jet for providing the atomizing effect; for providing the constancy of mixture composition he suggested maintaining a steady level of petrol column behind the jet. The jet itself was constructed as a hole (or several holes) in the sides of a tube put obliquely to the flow; for maintaining the flow consistency a small chamber with a floating unit was used, which kept the petrol column on a certain height (the float-chamber). The amount of petrol imbibed is in direct proportion to the volume of air flow being sucked in. In fact, Bankee suggested a method of calculation of a simplest carburetor.
