Historical electric/onic engine/body management

[barana]

Gday all,
I enjoy at times the historical aspect and tech,So I thought I'd start A thread on the subject in the title.Im not anything like a good writer with the ability to draw in readers like some have written, but I can write down the thoughts that lead me to seek out the info that im ..i dunno sort of journalling... Some articles are incredibly interesting(Analogue engine management is sortof a side interest of mine)
So a while ago I took what the old writers call a 'Walking tour' of the net searching for the remains of the first electric fuel injection controller.. that I subsequently discovered was installed on a WWII Aero. something about G's and upside down being incompatible with float bowls ..or something
What I did find is reference to an automotive electric fuel injection being installed on a car in Italy in WWII.

I recall a guy from the USA on his work trip to help install a machine here was telling me about what he claims the first car to have EFI. I think it was 1962 bmw with servo controlled injectors, like a water tap, it turned to open and close and control the flow.

I dont know of any such thing nor have seen any reference to it.

the only car I know of to have mass produced analogue EFI was the vw type 3 with its bosch D-Jetronic.

I had one of them and it was a huge improvement over the twin carb.

heaps of people still play with those vw type 3 "1600TLE" models and the EFI. The first release I believe was 1968

some info here

I also have hard copy of the schematics and a workshop manual section for the VW TLE model which has very detailed explanation of its operation.

I think it was Atlas who developed the first solenoid fuel injector system in the early 1930s, but the 1957(?) Bendix Electrojector is the earliest petrol EFI system I've heard of.

Not saying ive fact checked this, and i'd love for anyone to post any other systems by date outside of this.

In 1955 a mechanical fuel injection system was developed by Bosch in Germany. Two years later, in 1957, General Motors in the United States produced a mechanical fuel injection system.

The “Electrojector” developed by Bendix in the United States during the mid 1950s was one of the first electronic fuel injection systems. From 1957 it was offered as an option by Pontiac, De Soto, Chrysler, Dodge and Plymouth.

However, it was not reliable and was only fitted to about 35 cars.

Note: The Bendix fuel injection system was originally used on aircraft during the Korean War (1950-53).

Bosch later obtained patent rights to Bendix’s Electrojector system and during the 1960s Bosch developed their own “D-Jetronic” electronic fuel injection system.

This was first fitted to the VW Type lll in 1968. Between 1970 and 1973 the system was also used by Volvo, Saab, Renault, Porsche and Mercedes-Benz.

The D-Jetronic version was last used in 1976. Bosch introduced improved versions, including the L and K-Jetronic systems.

The Wright Brothers Engine No. 2 of 1904 had fuel injection :

cool, but i assume mechanical injection not electronic. i think in this thread we need to track what type

This is the caproni-fuscaldo system as fitted to a 2.5l 6cyl alfa racecar. It was simple, it ran off of a dedicated distributor.The injectors were solenoids.as I understand it, it was a development by an aero engineer for an automotive engine first,as it was an italian system, and this was wartime 39-41 the real info is surrounded in mystery as at the time italy's leader mussulini was sending a shedload of petrol to general franco in spain (another fascist style dictatior)Italy were also stockpiling petrol, preparing for war.The league of nations embargoed italy's petrol imports for its sale of juice to franco in spain.Meanwhile, 2 months after the running of this injected system in the mille miglia in '39(coming second only to a carburettored works Alfa Romeo 6C 2500 SS Type 256 Ala Spessa of the same type yet beating the other 6c's that were competing)Italy signed a steel pact with germany.
I could only find one drawing of the system, here.[img]http://www.flightglobal.com/FlightPDFAr ... 97.PDF[img]
This is a little bit on the car https://translate.google.com.au/transla ... t=&act=url

It used a distributor to fire the injectors so was even a sequential injection system

Well, all I can say is this not only predates the invention of the transistor (1947), it even predates the invention of the vacuum tube triode (1906)! So, definitely not electronic!

Delco did a cold carburation system in 1930 which was a cross beetween efi and carby and also desotto did a bendix system on chryslers 1958
