Electronic Fuel Injection (EFI) is a technology that has revolutionized the automotive industry by improving engine efficiency and reducing emissions. The invention of EFI can be traced back to the late 19th century, with various pioneers contributing to its development over the years. One of the earliest patents for an electric fuel injection system was filed by German engineer Wilhelm Maybach in 1893. However, it was the work of French inventor Étienne Lenoir in the 1880s that laid the groundwork for modern EFI systems. Lenoir's invention used an electric current to control the flow of fuel into the engine, which was a significant departure from the mechanical fuel injection systems of the time. This innovation paved the way for the more sophisticated and efficient EFI systems that are now standard in most modern vehicles.
