When did fuel injected engines come out on foreign vs. american vehicles?

Answer 1

Fuel injection has been used commercially in diesel engines since the mid 1920s.
One of the first commercial gasoline injection systems was a mechanical system developed by Bosch and introduced in 1955 on the Mercedes-Benz 300SL.

Then Chevy introduced a "Fuel Injection" system in 1957. Hope that helps you.

Answer 2

As someone has already said, fuel injection was first developed for racing in the mid-1950's, but it took a while to come to the consumer market. European cars definitely were equipped with it before American cars, but the difference was only 1-2 years.

Many people preferred carburation over fuel injection until the systems became reliably computerized (in the early 1980's), though.

Answer 3

Foreign cars had fuel injection long before American cars did. Usually the more expensive cars. Extravigant. Fuel injection started showing up on the racing scene in the late 50's.
