Carburetor
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.
Carter Carburetor
Carter adapted carburetors for Willys Jeep four-cylinder engines, waterproofing them for water crossings and making it possible to keep the engine going even on a steep incline (the Y-S carburetor). Carter also produced the first American four-barrel carburetor, used for Buick’s 1952 straight-eight, and followed by the WCFB on the 1955 Chrysler C300. This was eventually superseded by the AFB and the AVS. The final Chrysler use of four-barrel Carter carburetors was the Thermo-Quad, which used a lightweight thermoplastic float bowl, on the most powerful Chrysler engines.
