EFI question

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

EFI question

Post

When was it first introduced? Just curious.
I don't suffer insanity. I enjoy every minute of it.

Early '80s on production cars while F1 engines were using mechanical all the way to early-mid '80s. Than I believe they slowely switched to Bosch jetronic and later Marelli. Can't tell you the exact years and engines but try searching it can be found on web.

Been checking a bit more and the sources also mention Lucas as supplier for various teams, Renix for Renault, Bosch that I mentioned was working together with Kugelfischer at the beginning (sort of transition from mechanical Kugelfischer to full Bosch EFI).

fuel injection

Post

Mercedes-Benz used direct cylinder injection on their DB601 V12 aircraft engine in 1937. In the US, Offenhauser used Hilborn constant flow port injection on his 1952 Indy engine. And of course, the Cosworth DFV had a Lucas mechanical CIS system (in 1967?).

True, but those are all mechanical. "Silver-Arrowz" was inquiring about EFI.

first use of EFI

Post

manchild,

Sorry.....I should have read the original post more carefully.

As for automotive applications, the Bendix "Electrojector" system was available in the late 50's, but I don't think it ever went into production. The Bosch Jetronic was available on VW's in 1968 (analog controller and solenoid delivery valve).

Regarding race applications, by 1983/1984 most F1 engines were running EFI systems such as the Bosch Motronic. Don't know exactly who was first, but back then, budgets were not what they are now. So most ECU's were production based to save money.

riff_raff,

E in EFI stands for Electronic not Electric, there is the difference.

I agree with second part of your post regarding F1 use (by 1983/1984) which is more-less in compliance with what I've posted before saying that "...F1 engines were using mechanical all the way to early-mid '80s". That is if you agree that early mid-'80s are 1983 and 1984 as you mentioned :wink:

the Corvette SS that raced at Sebring (WSC) in 1957 had Delco/Rochester electronic fuel injection
presumably the same technology as the $484 option on road Corvettes and some other Chevrolets from 1957
this was an analogue system with vacuum tubes/thermionic valves in its amplifier

the Lucas (mechanical) system was introduced on the 1956 D type Jaguar
but didn't become dominant in F1 till 1962
in F1 Vanwall used Bosch from 1955 on, as did Ferrari from 1963
John Surtees said it was inferior, he should know
the Hilborn was used by Connaught in the WDC in 52 or 53 (only possible due to alcohol fuel)

Yes, this was a major contributor to their superiority, right?

This article says Honda introduced the PGMFI system on its turbo bikes in 1982.

1975 datsun 280z had what we now call a "bosch generic" digital fuel injection system (L jetronic) while the cadillac seville of the same year had a bendix of similar operating principles.

Earlier bosch D jetronic was an analog fuel injection system that used breaker points to trigger it as found on the porsche 914 but earlier found first on the VW type III of 1967 and the type IV in 1968........love those cars.

Both D-jetronic and L-jetronic units were also found in various volvo and mercedes cars in spite of the fact that the mercedes also had CIS injection on most models.

Don't forget that the aston martin DBS V8 came with bosch fuel injection in 1969 before going to webers.

The first "EFI system" offered on a production car was on the 1958 chrysler 300 with a 390 horsepower chrysler hemi.
