Custom Fuel Ice Box

[Bliksem]

I just found this on another forum and had a good laugh...

Does anyone actually think this would work ?

Hey guys,

Ive always been facinated as to why people put on huge intercoolers to cool intake air, but dont cool the other crucial element of the combustion system: fuel

Basically, an engine needs two things to run: Fuel and Air. The colder the incoming air or fuel, the denser it is, thus the more air and fuel that can be packed into the combustion chamber, and the more that is burnt in the explosion (less wasteage)

This in turn makes more power, and more power means more fun!!!

I had a big problem last year with my Gem during the 40+ degree summer. The car was very laggy, and a downright pain to drive, due to the heat.

I created an intercooler spray system, that sprayed directly onto the front and rear of the main core that was operated off a manual switch inside the cabin.

This did have alot of effect on the car at 50kph or more (Air temp - 40 degrees down to 20 degrees = 50% reduction).

NOTE: Intercooler cost over $2k from Mr Enforcer Engineering, and was custom built for my Gemini.

Now, Im pretty unsure of water injection setups. The idea of water pouring into the combustion chamber really freaks me out. My grandfather has done alot of work with such setups from the 50s onwards, and has had great success.

Ill be looking more into this at a later date.*

These setups Ill be looking at using on my next car, as I think nothing will save the Escort

Ive done a bit of research into basic fuel cooling setups, but havent come up with much. Seems there isnt much a need out there, but plenty for huge truck intercoolers.

I have to stress the ice wont last forever, and that its not ment to be a permanent solution to the problem, although the empty box would also double as a heat sheild around the fuel line.

So here goes. Anyone with ideas, please post up at how I can improve my design.

CUSTOM FUEL ICE BOX

* The box or cylinder will be lined with a dense foam, so the ice dosent come into contact with the sides. The metal exterior will be hot from the engine bay, and will cause the ice to melt faster.

* The fuel line will be coiled/spiralled around a central point. Corners would create pressure, and slow the flow speed of the fuel.

* Ice will be packed around the the spiralling fuel line. NOTE: the coil has plenty of width to the outer edge, so ice can be packed in.

* The box will have a drainage outlet, that would pass into the radiator overflow tank.

Its all about R & D. Lets go!!!

I know petrol has a stupidly low freezing point so that won't be an issue, but, won't that seriously mess with the fuel atomization?

As we all know, cool air has more oxygen per given volume allowing you to put more fuel in and make more power. The same can't be said for petrol, cooling it does nothing to the overall volume so why would you bother?.

Contrary to popular belief, water injection has NOTHING to do with "cooling" the fuel, it is there simply to reduce the chances of preignition (pinging) in high compression or blown engines.

Even if chilling fuel were to benefit, alot of heat would be put back into the fuel once it passes through the injector rail etc.

Easier just to buy a Cryo2 product

cooling the fuel can have a bad effect. mitsubishi magnas have a problem where they get a lean spot after fitting a k&n filter. the solution is to put alloy spacers in the fuel rail to heat the fuel up to get it to atomize better.

Yes, not to mention water heated manifolds to help with atomisation...
