Back to simplicity: Would carbureted ethanol-only cars pass new car emission tests?

A high-altitude nuclear strike will cook your EFI while nothing short of a direct lightning bolt (or a solid whack with a big hammer) will disrupt the function of your carburetor.

Outside a nuclear war. There is that little asterisk.

Aren't you more likely to suffer an EMP pulse from an overzealous SWAT tream? Unless you make a Faraday cage in your engine compartment? That would put you a step ahead of, oh say, Telsas.

A step short of Armageddon might be a volcanic eruption like Mt St. Helens. It was a localized 'nuclear winter' and anything that didn't have a massive cleanable air filter stopped dead in it's tracks. EFI'd or carbed.

That's my rationalization for driving a 40-year-old car. It's not a land yacht, I consider it a mid-size compared to something really economical. It's a VW Beetle.

As for the second point, you might want to look at Cool Planet. Biomass to 110-octane gas-o-line.

I had EFI once. The first one—the VW Type III. Eventually I couldn't source a replacement temperature sensor and it went to carbs. Big, HONKING Webers. They sounded like Gabriel's trumpet.

I look on a carburetor as an analog computer where the feedback loop is through constant hand tuning. There is a field of study called Fluidics. It involves logic circuits and amplifiers implemented in rigid chambers and moving fluids (like gas, or air ) I'd look for anti-detonation elsewhere, though. Maybe sensors in the spark plugs and put it in the ignition system.

Got an SU type on my bike, old tech EFI on the 97 Ranger, new tech with two independently varaible cams in the Fiesta. With the powershift the Fiesta with AC is getting almost the same mileage as my old Echo manual with no AC.

If I had or have a carburetor it would be like the SU types on the first 240Z built in 1969. Single point of delivery like EFI, good mileage and excellent throttle response. That car taught me to keep the ball of my clutch foot on the floor, throttle response was so quick.

There were also other similar carburettors such as the Stromberg CD and a few Japanese copies made by Keihin and Hitachi.
