Fuel injectors are one of the greatest technological inventions for automobiles, improving fuel efficiency and reducing environmental impact. The history of fuel-injected automobiles dates back to the early 1900s, with the first fuel-injected compression-ignition engine constructed in 1902 by French aviator Leon Levavasseur. This technology was initially used exclusively in aircraft engines, with the first fuel-injected production sports car introduced by Mercedes-Benz in 1954. In the 1960s, European automakers began experimenting with mechanical fuel injection, and by the 1970s, fuel injection was appearing in mainstream cars. The development of electronic fuel injection (EFI) systems further improved efficiency and user-friendliness, with the first EFI system offered in a production vehicle by Bendix in 1957. Today, all cars are fitted with electronically controlled fuel injection, showcasing the evolution of this technology over the past century.

The first fuel-injected compression-ignition engine was constructed in 1902 and entered production in 1906
The history of fuel injection in automobiles dates back to the early 1900s. The first fuel-injected compression-ignition engine was constructed in 1902 and entered production in 1906. This engine was designed by the French inventor, aviation pioneer, and aviator Léon Levavasseur, who implemented a prototype version of an injection system into his Antoinette 8V airplane. This was the first V8 engine system installed in any vehicle in history.
The Antoinette 8V was similar in principle to a compression-ignition engine, although it used an external heat source, rather than compression, to ignite. It was also the first production V8 in history. The engine was French, but one might assume it originated in the USA, the Promised Land of the eight-cylinder engine.
In the years following the debut of the Antoinette 8V, fuel injection systems were further developed and adopted for use in aircraft engines. During World War II, money and resources were poured into exploring innovations, with the hope that any technical improvement would lead to an advantage over the enemy. This resulted in the use of fuel injection systems in fighter planes such as the German Luftwaffe's Messerschmitt Bf 109s, which were able to outperform the British Spitfire and Hurricane planes that were fed by carburettors, which resulted in fuel supply interruption during negative-g manoeuvres.
In the 1940s, racers and hot-rodders began to experiment with mechanical fuel injection, and by the 1950s, fuel injection systems were appearing in automobiles, with Mercedes-Benz embracing mechanical fuel injection in the form of Bosch direct injection. In 1954, Mercedes-Benz outfitted a 300SLR with the Bosch direct injected aircraft engine, which Stirling Moss drove to victory in the 1955 Mille Miglia. In the same year, Chevrolet introduced its "Small Block" V8, which was fitted with Rochester fuel injectors, and the British company Lucas came up with its own variant of fuel injection, which was fitted to Jaguar racecars. By the 1970s, fuel injection was appearing in mainstream cars, and since the mid-1990s, it has been impossible to buy a new car without fuel injection in Europe.

The first direct-injected compression-ignition engine used in road-going vehicles was the Hesselman engine, introduced in 1925
The history of fuel injection in automobiles dates back to the early 1900s, with the first fuel-injected compression-ignition engine being constructed in 1902 and entering production in 1906. However, the first direct-injected compression-ignition engine used in road-going vehicles was the Hesselman engine, introduced in 1925 by Swedish engineer Jonas Hesselman.
The Hesselman engine was a hybrid between a petrol engine and a diesel engine. It was designed to address the limitations of contemporary diesel engines, which required high compression and pressure during combustion, making them heavy and challenging to start. Hesselman engines had lower compression ratios, allowing them to be smaller, lighter, and cheaper.
One of the key advantages of the Hesselman engine was its ability to burn low-quality, cheaper fuels. It could run on various fuels, including fuel oil, kerosene, petrol, coal-derived tar-oils, alcohol, and conventional diesel fuels. This versatility was particularly useful given the inconsistent fuel supplies available during that era. The engine also offered better fuel economy compared to petrol engines of similar performance at the time.
In practice, Hesselman engines had higher efficiencies than carburetor spark ignition engines but lower efficiencies than diesel engines. They were used in heavy trucks, buses, and industrial applications. However, they faced some challenges, such as incomplete combustion, which led to spark plug fouling and toxic exhaust emissions. Despite these drawbacks, the Hesselman engine remained in production until 1951, with continuous improvements being made to address these issues.

Fuel injection technology was used in German aircraft engines during World War II
The history of fuel injection technology dates back to the early 1900s, with the first fuel-injected compression-ignition engine constructed in 1902 and entering production in 1906. Initially, fuel injection was used exclusively in aircraft engines, continuing through World War I and World War II.
During World War II, fuel injection technology played a significant role in the performance of aircraft engines. The German Luftwaffe, in particular, utilized advanced fuel injection systems in their planes, giving them an advantage over their opponents.
One notable example was the use of Daimler-Benz 601 V12 engines in German fighter planes such as the Messerschmitt Bf 109s. These engines, equipped with fuel injection, did not suffer from fuel supply interruption during negative-g manoeuvres, unlike the carburetted Rolls-Royce Merlin engines used in British fighters like the Supermarine Spitfire and Hawker Hurricane.
The BMW 801 engine, which powered the feared Focke-Wulf Fw 190 fighters and Junkers Ju 88 bombers, was another instance of German aircraft engines employing fuel injection technology. This 42-litre, air-cooled radial 14-cylinder engine demonstrated the German aviation industry's prowess in utilizing fuel injection for enhanced performance.
Additionally, the Junkers Jumo 210 engine, found in the Ju 87 Stuka dive bomber, and the Jumo 211 engine, used in the Heinkel He 111, were both equipped with fuel injection systems. These German aircraft engines showcased the widespread adoption of fuel injection technology during World War II, contributing to the overall effectiveness of their aerial warfare capabilities.

In 1954, Mercedes-Benz also built the first fuel-injected production sports car, the 300 SL, nicknamed the "Gullwing" for its swing-opening doors. That same year, Chevrolet introduced its "Small Block" V8, which was fitted with Rochester fuel injectors, and the British company Lucas came up with its own variant of fuel injection, which was fitted to Jaguar racecars.
By the 1970s, fuel injection was becoming more common in mainstream cars, and by the mid-1970s, Japanese automakers had joined their European and American counterparts in offering EFI-equipped automobiles. In the 1980s, fuel injectors began to quickly overtake carburetors in auto design, and by the mid-1990s, it became impossible to buy a new car without fuel injection in Europe.
