The first mass-produced direct fuel injection system was developed by Bosch and used in Goliath GP700 in 1952
The history of direct fuel injection in cars is a long and complex one, with many companies contributing to its development over the years. One of the key players in this story is the German company Bosch, which has been at the forefront of fuel injection technology since the early days of the automotive industry.
In the 1930s, Bosch began developing a mechanical gasoline direct injection (GDI) system for cars. This technology was based on diesel injection systems and was first used in aircraft engines during World War II to prevent engine stall-out during high-speed aerial maneuvers. After the war, Bosch continued to refine its GDI system, and in 1952, it was introduced in the Goliath GP700, a small saloon car produced by the Bremen-based car company, Goliath.
The Bosch GDI system in the Goliath GP700 was a high-pressure diesel direct-injection pump with an intake throttle valve set up. This system offered several advantages over traditional carbureted engines, including improved performance and up to 30% less fuel consumption, particularly under low engine loads. The Goliath GP700 was the first mass-produced car to feature direct fuel injection, although only a handful of these vehicles were built.
Following the Goliath GP700, Bosch continued to supply its GDI system to various car manufacturers, including Mercedes-Benz, which used it in its 1954 W196 Formula One racing car and its 1955 300SL sports car, the first four-stroke engine to use GDI. However, despite the benefits of GDI, it remained a rare technology in the automotive industry until the 1990s due to its high cost and various technical challenges.
In the mid-1990s, Mitsubishi introduced the first mass-produced GDI engine for the Japanese market, leading to a rapid increase in the adoption of GDI technology by car manufacturers worldwide. Today, GDI systems are commonly used in both entry-level and high-performance vehicles, demonstrating the significant impact of Bosch's pioneering work in this field.

The first four-stroke direct-injection petrol engine for a passenger car was released by Mercedes-Benz in 1955
The history of direct fuel injection in cars goes back several decades. During World War II, Germany began equipping its fighter aircraft with direct fuel injection to prevent engine stall-out during high-speed aerial manoeuvres. German aircraft engines such as the Daimler-Benz DB 601, DB 603 and DB 605 used gasoline direct injection (GDI).
In the post-war era, automotive manufacturers in Germany and abroad began experimenting with direct fuel injection in cars. The first mass-produced petrol direct-injection system was developed by Bosch and introduced in 1952 for small automotive two-stroke petrol engines, including the Goliath GP700 and Gutbrod Superior.
However, the first four-stroke direct-injection petrol engine for a passenger car was released by Mercedes-Benz in 1955. The 1955 Mercedes-Benz 300SL sports car used an early Bosch mechanical GDI system, becoming the first four-stroke engine to use GDI. This engine suffered from lubrication issues due to petrol diluting the engine oil, and subsequent Mercedes-Benz engines switched to a manifold injection design.
Despite these early developments, direct fuel injection did not become widespread in passenger cars until much later. In the 1970s, fuel injection began appearing in mainstream cars, and by the mid-1990s, it became mandatory for all newly introduced engines in Europe to be fuel-injected. In 1996, Mitsubishi widely introduced their GDI system, making it the first mass-produced car to use GDI. This technology was soon licensed by other manufacturers, leading to rapid adoption in the automotive industry.

Mitsubishi introduced gasoline direct injection (GDI) systems in 1996
The history of direct fuel injection in cars goes back to the 1920s, with the first GDI engine introduced in 1925 for a low-compression truck engine. During World War II, German aircraft engines used GDI, and German car manufacturers began using Bosch mechanical GDI systems in the 1950s. However, the technology remained rare until Mitsubishi introduced gasoline direct injection (GDI) systems in 1996.
Mitsubishi's 1996 GDI system was an electronic version designed for mass-produced cars, marking a significant milestone in the adoption of this technology. The Japanese-market Mitsubishi Galant was the first mass-produced car to use a GDI engine, with a GDI version of the Mitsubishi 4G93 inline-four engine. This technology was then brought to Europe in 1997 with the Carisma model, and Mitsubishi also developed the first six-cylinder GDI engine, the 6G74 V6, in the same year. By 2001, Mitsubishi had produced over one million GDI engines across four families of engines.
Mitsubishi's GDI technology offered several advantages, including increased fuel economy, higher power output, higher maximum torque, lower weight, and reduced production costs compared to diesel engines of comparable capacity. The use of GDI can also help increase engine efficiency, specific power output, and reduce exhaust emissions.
While Mitsubishi was a pioneer in the mass adoption of GDI technology, other manufacturers have also contributed to its development and refinement. Several Japanese and European manufacturers introduced GDI engines in the years following Mitsubishi's introduction. Peugeot, Citroën, Hyundai, Volvo, and Volkswagen licensed the Mitsubishi GDI technology, further expanding its reach and influence.
In recent years, GDI has seen rapid adoption by the automotive industry, with a significant increase in the United States from 2.3% of production for model-year 2008 vehicles to approximately 50% for model-year 2016. This trend reflects the benefits of GDI technology and its potential to enhance engine performance and reduce emissions.

By 1970, fuel injection was appearing in mainstream cars
The history of fuel injection in cars dates back to the early 20th century, with the first fuel injection systems introduced in aircraft engines during World War II. In the post-war era, automotive manufacturers began experimenting with fuel injection in cars, but early attempts were limited by the technology of the time.
By the 1950s, fuel injection started to appear in passenger cars, with the 1952 Goliath GP700 becoming the first car to feature a direct-injection system. This system, developed by Bosch, was initially used in small automotive two-stroke petrol engines. The 1954 Mercedes-Benz W196 Formula One racing car also featured a Bosch mechanical direct-injection system, showcasing the potential of fuel injection in high-performance vehicles.
Over the next two decades, fuel injection technology continued to evolve, with various manufacturers introducing their own fuel injection systems. By the 1970s, fuel injection had gained significant traction and was appearing in mainstream cars.

The first petrol engine with direct injection was a two-stroke aircraft engine designed by Otto Mader in 1916
The history of direct fuel injection in cars is a long and complex one, with the technology evolving significantly over the past century. The very first petrol engine with direct injection was a two-stroke aircraft engine designed by Otto Mader in 1916. This pioneering engine was a significant milestone, paving the way for future developments in fuel injection technology.
Mader's engine was designed for the Junkers airplane, initially as a diesel engine. However, due to a decree from the German ministry of war, it was switched to run on gasoline, as aircraft engines were required to operate on either gasoline or benzene. This engine featured a crankcase-compression two-stroke design, and to prevent potential engine destruction from a misfire, Junkers developed a gasoline direct injection (GDI) system. Unfortunately, the end of World War I brought a premature conclusion to its development.
Despite this setback, the concept of direct fuel injection persisted and evolved. During World War II, Germany equipped several of its fighter aircraft with GDI systems, preventing engine stall-out during high-speed aerial maneuvers. This technology was also adopted by the Allies, with the American Wright R-3350 Duplex Cyclone engine and the Soviet Shvetsov ASh-82FNV radial engine both utilizing GDI.
In the post-war era, the German company Bosch played a pivotal role in advancing GDI technology for automobiles. They began developing a mechanical GDI system for cars in the 1930s, and in the 1950s, several German cars utilized this innovation. However, it wasn't until 1996 that an electronic GDI system was introduced by Mitsubishi for mass-produced cars, marking a significant turning point in the automotive industry.
Since then, GDI technology has seen rapid adoption, with its benefits becoming increasingly apparent. GDI systems offer improved fuel efficiency, increased power output, and reduced exhaust emissions. By 2016, approximately 50% of model-year 2016 vehicles in the United States featured GDI engines, showcasing the technology's dominance in the market.
