Back in the days of the MK 1 Ford Cortina (early 60's?) there was a Cortina
converted to need no carburettor. The fuel tank had no breather hole at
the top, instead a pipe led from outside to almost the bottom of the tank so
air could only enter by bubbling up through the petrol resulting in a
combustible vapour at the top. This was collected, using the suction of
the engine intake, by a hose attached to the tank top and it lead straight
into the engine via a butterfly throttle valve and some sort of safety
device in case of blow back. It used far less petrol than the
conventional design and the car performed much better. Of course the
health and safety people nowadays would have a field day. Last I heard,
one of the carburettor manufacturers (SU, Solex or whoever) was supposed to
have bought the patent and killed it stone dead.

I am told that the grill things on the ground at filling stations are
there to recycle the fumes given off when filling up. So you pay for the
fuel then the garage gets some back!

I believe it was toyota that had a lean burn engine in their carina
several years ago, the principle of it is the same, once a car is at
speed you need less fuel to keep it up to speed and so you can run it
with a leaner mixture.
i experimented with that on a light motorbike ( yamaha DT) by having
air induction on the air filter side and a smaller venturi in the
carburetor giving the air more speed over the nozzle
it allowed to reduce nozzle size by some 25% and thus having about the
same effect on fuel consumption.
of course it meant that pulling away for first corner at traffic light
pole position was out of the question but that time was made up for in
spending less time at the petrol station
Of course the

the thing is with that principle that you have to have a more or les
consistent fuel temperature in order to get the mixture right, i.e.
the colder it gets the leaner the mixture will be. So i dont think the
patent was killed, It might have died of natural causes
