You know how intercoolers work on a forced induction engine?

Do you think the same principle could be applied to fuel? If you had a good fuel pump and regulator, do you think you could run your fuel through a radiator to cool it down a bit more and increase energy density?

The main problem I can think of is that your fuel isn't actually very warm to start with, not like intake charge.

Run your fuel pipes through an electric fridge? Only drive in polar regions?

This will likely not work well because if you spray it into the intake the viscosity may be too high to cool the air effectively. That is, the viscosity will not enable the fuel to mist as well.

It is better to heat the fuel anyway. Effectively this puts energy into the engine system, thus increasing efficiency and power assuming the air intake volume doesn't significantly change. The hotter fuel will not cool as effectively either, which should be obvious because its temperature is now higher.

As it is, the fuel should be approximately the temperature of ambient air, so an intercoler would do nothing unless you had an evaporator system. If you were to cool it with refridgerant, you would lose more power than you gain anyway, unless you used something like an evaporative ammonia system which works off waste heat energy.

The only reason to cool the fuel is for gaining slightly more power by cooling the air more, but the ECM or carburetor will do this anyway by enriching the intake charge. In fact, this is the reason that carbs can ice over.

Um, gasoline is pumped in a liquid state so a change in temp is going to have a tiny change on the density.

Found this on wiki

"The following shows the key specifications issues for each class. It was also introduced for the 2005 year, that under rule 2.10.5: 'No fuel on the motorcycle may be more than fifteen °C (15 °C) below ambient temperature. The use of any device on the motorcycle to artificially decrease the temperature of the fuel below ambient temperature is forbidden. No motorcycle may include such a device.' This stops an artificial "boost" gained from increasing fuel density by cooling it."

So it appears that it would have some effect on performance, unless the wiki article is bullshit

$109?

I could make one myself with a decent cool box, some unions and some copper pipe.

I wonder if these actually work...

That's what I was thinking, but I think it'd come out pretty steep in the end if you use all new bits, just like Moroso have done (though they've done it in bulk so they can get better profit margins into that $109).

Basically, it's just this is a thermal box:

The point is that your idea is, if nothing else, marketable.
