It was a trick with ultrasonics. There had been rumors of ultrasonic
carburetors in GM for several years, the so-called 30 mpg box, and it was
supposed to be wired with transducers and such. Of course, the guy I ran
into who claimed to really have one until the first service on his new '74
Impala could have just been describing an early test Q-Jet with the
electronics plugged in. He claimed he got around 20 mpg with his Impala
and
then 13 when it was gone.
I positioned an ultrasonic transducer above the barrels and pumped in a
40khz signal. I really didn't have anything to base it on and was just
trial and error. The transducers I had were surplus electronics items and
were not designed for the heat, gas, or anything, so they failed after
about
a week. I went through 4 of them.
The idea was that ultrasonics let the gas and air atomize better and that
would improve fuel economy. It appears that it did. With more time,
money,
and equipment, it might have been a good deal, positioning them under the
carb, in the intake, or maybe above and below, but I didn't have the
resources to do all that. I never had the chance to really tune for
mileage
as by the time I ran enough miles and gas, they had failed. If I had
transducers that could have lasted, I could have tried turning the carb
for
the ultrasonics and seen if they actually
Since them, the EFI, TBI, and TPI all have created much better atomization
than carbs did so it is academic today. If it improved over the fuel
injection, it might only be 1 mpg or so, and that isn't really worth the
effort.
