It's been a long time since carburetors controlled the flow of fuel into the engines of new cars. Today, all new cars use some form of electronic fuel injection. How did this innovation come about? The introduction of computer chips into cars allowed for the kind of precision that fuel injectors needed to be really successful. This article from Edmunds.com explains a little about the history of fuel injection, the main components that go into an injection system, and the advantages over old-style carburetors.
Injection comes of age
Car technology has come a long way. Disc brakes replaced drums, electronic ignition replaced mechanical, and injection systems replaced carburetors.
The computer
Three main components go into an electronic injection system: computer, sensors, and injectors. Find out how they work together.
Why EFI is better
Carburetors are pretty finicky compared to injection systems. The trade-off has won us more efficient vehicles that require less maintenance.
