Fuel Injection History

Most engines these days are what the industry calls fuel-injected. If you are not car savvy, you overlook this detail with a shrug and move on down the list of more exciting and tangible features for the vehicle in question. But what does fuel-injected mean? Maybe we should stop and do a little reading on what this engine does and where it came from. Are there better options? Has there ever been another option?

The fuel-injected engine became the primary fuel delivery system during the 1980s and they replaced having the need for a carburetor. The main difference in these two engine types is that the fuel injection system forcefully pumps gas through a small nozzle which is under high pressure. The carburetor relies on suction to draw fuel into the airstream.

Even though many modernized vehicle engines didn’t see this technology until the 1980s, the Germans had dabbled into it during World War II in their fighter aircraft. But, even earlier than that, around the turn of the 20th century, a man by the name of Herbert Akroyd Stuart created the first system that closely resembles what we have today.

By the 1920s, this system was used mainly for diesel engines. During the 1950s, Chevrolet began working on their fuel injection system as well. Their take on the invention was to meter the flow of fuel by a collection of injection lines instead of just a “pulse” used by other developers. This allowed their engines to adjust the flow of fuel according to the load and speed of the vehicle.

Not much changed from the 1950s until the 1980s when the first fully digital electronic fuel injection system was invented. Electronic fuel injection mixes an appropriate amount of fuel and air in an internal combustion engine. This has become the standard of many vehicles and is still used today. It has almost completely replaced the need for a carburetor.

One major advantage of having a fuel-injected engine is that you get better fuel economy and more power. The car also produces less carbon-based emissions and drives smoother than one with a carburetor.
