What year did EFI start?
Electronic Fuel Injection (EFI) is a technology that has revolutionized the automotive industry, but do you know when it first emerged? The answer may surprise you. EFI, a system that precisely controls the amount of fuel delivered to an engine, was first introduced in the 1950s, marking a significant milestone in the evolution of engine technology.
The Early Days of EFI
The origins of EFI can be traced back to the 1950s, when automakers began experimenting with electronic fuel delivery systems. Bosch, a German engineering and technology company, is credited with developing the first production-ready EFI system in 1967. This system, known as the Jetronic, was initially used in the Volkswagen 1600 TL and quickly gained popularity among other automakers.
The Jetronic system represented a significant departure from the traditional carburetor-based fuel delivery systems that had dominated the automotive industry for decades. Instead of relying on a mechanical device to mix air and fuel, the Jetronic system used electronic sensors and a computer-controlled fuel injector to precisely deliver the right amount of fuel to the engine.
The Advantages of EFI
- Improved fuel efficiency: EFI systems can precisely control the air-fuel ratio, leading to more efficient combustion and reduced fuel consumption.
- Enhanced engine performance: EFI systems can respond more quickly to changes in engine load and speed, resulting in improved acceleration and power output.
- Reduced emissions: By optimizing the air-fuel ratio, EFI systems help reduce the amount of harmful emissions produced by the engine.
- Easier engine starting: EFI systems can provide the right amount of fuel for cold starts, making it easier to start the engine in various weather conditions.
As the benefits of EFI became more apparent, the technology quickly gained widespread adoption in the automotive industry. By the 1980s, EFI had become the standard fuel delivery system for most new vehicles, replacing the traditional carburetor.
The Evolution of EFI
Since its introduction in the 1950s, EFI technology has continued to evolve, with advancements in sensors, computer processing power, and fuel injector design. Today, EFI systems are more sophisticated than ever, with the ability to precisely control fuel delivery, ignition timing, and other engine parameters to optimize performance and efficiency.p>
The impact of EFI on the automotive industry cannot be overstated. By improving fuel efficiency, reducing emissions, and enhancing engine performance, EFI has played a crucial role in the development of modern, environmentally-friendly vehicles. As the industry continues to push the boundaries of engine technology, the legacy of EFI will undoubtedly continue to shape the future of automotive engineering.
When did EFI become standard?
The first examples started to appear in the 1950s. By the 1970s, fuel injection was appearing in mainstream cars. Since the mid-1990s, it has been impossible to buy a new car without fuel injection in Europe (all newly introduced engines have had to be fuel injected from 1992).
What was the first car with EFI?
In 1958, the Chrysler 300D, DeSoto Adventurer, Dodge D-500 and Plymouth Fury offered the Electrojector system, becoming the first cars known to use an electronic fuel injection (EFI) system.

When did Toyota go to EFI?
Engines
| Year | Technology developed and applied |
|---|---|
| 1967 | Twin-cam Type 3M engine developed |
| 1971 | Sintered-alloy valve seats adopted in the Type 4M engine |
| Electronic fuel injection (EFI) system adopted in the 18R-E engine | |
| 1973 | Exhaust gas recirculation (EGR) system adopted in the 18R-C engine |
When did GM stop using carburetors?
FWIW, the last GM carbureted engine was built in 1990.
What year did dirt bikes get EFI?
Fuel injection first found its way into production on a mainstream motocross machine in 2008, when Suzuki made it part of the RM-Z 450. Yes, other, smaller brands tried it, like the Cannondale of the late 1990s, but Suzuki was the first to add EFI to a proven platform.
What year did the F150 get EFI?
For 1984, a high-output version of the 5.8L V8 was introduced. The 5.0L V8 was fitted with fuel injection as standard equipment for 1986, becoming the first fuel-injected engine in an American-market pickup truck. The 4.9L was fuel injected on 1987 models.
What year did Honda start EFI?
1982
The CX500 Turbo (a 500cc export model) was the first Honda motorcycle to be sold with fuel injection, in 1982.
Is a 1987 Ford F150 fuel injected?
Powertrain and chassis. In a move to further update the F-Series engine lineup, the 4.9 L inline-6 was converted to fuel injection for 1987.
What year did Chevy start using EFI?
The 1957 Chevrolet Corvette Super Sport that General Motors proudly paraded around the show circuit nearly 65 years ago was no ordinary Corvette. It was, in fact, a game changer—the first to feature high-performance Ramjet fuel injection.
