Has anybody looked into Fuel Cooling in order to release a few extra BHP for not a lot of effort ??

 

If so, what did you do?, Im thinking of introducing a separate air cooler somewhere , somehow,

 

I also wonder what power could be released with sufficient cooling, or even charge cooling on the fuel system.

 

Thanks.

The stock fuel rail has a thermometer that tells the ECU. I believe fuel pressure is effected in this scenario.

It's more to do with intake charge temps and density rather than fuel temperature. Fuel burns as a vapour, it doesn't matter what temperature it is in its liquid state, it will always have the same flash point based on its octane and other properties.

 

A fuel that burns cooler like E85 has higher octane at a lower flash point, it isn't to do with the temperature its stored at in its liquid state.

 

The ECU can compensate fueling relative to fuel temperature anyway, but it's not the main factor.

 

Larger intercoolers will help you more in this weather and in general anyway.

Absolutely correct.

None whatsoever.

As already said fuel is vapourised before combustion so liquid temp is irrelevant. It gets cooled all the time as it circulates back to the tank which remains cool as its under the vehicle..

Cold air is whats needed as colder air can hold more fuel suspended in it.

To aid hot starting when fuel can vapourise in the fuel lines, the ECU has a fuel temperature sensor. When it goes above

the temperature threshold (75C) the ECU signals the PRVR solenoid for ~30 seconds to increase fuel pressure at engine start.

Did someone mention larger IC's...

They're still in your conservatory aren't they...….!!!

Thank you for the additional info Andrew. It was in the recess of my mind as I was concerned what impact would be had as my sensor is open circuit. After looking, I’ve deleted my PRVR so the impact, not much. Still intend to fix it though.

That’s what I’ve got on my zed V3 plus all the pipework.

the ideal is the ethanol fuel E85, the octane number greater than 100 allows a more aggressive ignition and more turbo pressure

 

in France, with identical configuration the gain can vary from 30 to 50 hp

In my game, we run the fuel through a fuel heater!

 

In Sibera in the winter they do too! Diesel turns to gloop. :lol:
