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.
Frederick W. Lanchester
Lanchester began to find the conflict between his job as works manager and his research work irksome. Therefore, in 1893, he resigned his job in favour of his younger brother George. At about the same time, he produced a second engine type similar in design to his previous one but operating on benzene at 800 rpm. An important part of his new engine was the revolutionary carburettor, for mixing the fuel and air correctly. His invention was known as a wick carburettor, because fuel was drawn into a series of wicks, from where it was vapourised. He patented this invention in 1905.
