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.

The 2G (later 2GC and 2GV) carburetor, commonly called the 2 Jet, was introduced in 1955, and continued to be used on GM V8s until at least 1969. In all, it was used in at least 125 applications, including the Brockway's inline six. In 1957 Chevrolet introduced their first fuel-injected engine, the Rochester Ramjet high-performance option on Corvette and passenger cars at $484. In 1956 Oldsmobile were also experimenting with Rochester fuel injection, at the GM desert proving grounds near Phoenix, but offered the Rochester triple-carburetor J2 option for 1957.
