Adamfiza80 Member 73 Member For: 11y 26d Gender: Male Location: Newcaslte Posted 28/02/14 01:19 PM Share Posted 28/02/14 01:19 PM Has anyone got some info or put some thought into fuel temperature just prior to injection into cyclinder? I noticed that my pcw dual surge tank was pretty damn hot after a short run or 20mins to get my car up on a hoist. Its was a fairly hot summer day and there was no problem with the car.It just got me thinking. Is the engine performing best when the fuel is close to its combustion point as in for my experience it is in a coal fired power station furnace? Or will this higher temperature hinder the lower air intake we all look for with running E85.....Thoughts? Link to comment Share on other sites More sharing options...

This is why manufactures strive to create systems that run fuel cooler.To run a surge tank system , especially close to engine and exhaust is prime candidate for heating fuel. KPM have engineered direct replacemant fuel pump systems to be housed intank as OEM that deliver cool fresh fuel up to 1000HP quitely , efficiantly, safely without any hassle of external tanks.

I took the pump out of my EL on a 38c day, fuel burnt my hands. I couldn't believe the temp. If you wanted to do something, you'd want to get some sort of liquid to liquid cooler back to the rail. I say an exchanger setup as it's probably not wise to mod the rail infront of the rad if there is a crash Link to comment Share on other sites More sharing options...

Found an interesting study comparing pump 98 to E85 but more inregards to IAT, timing, knocking and pinging. It was an indepth study but the fuel was kept at an average ambient temperature. http://www.google.com.au/url?sa=t&source=web&cd=1&ved=0CDIQFjAA&url=http%3A%2F%2Fdspace.mit.edu%2Fbitstream%2Fhandle%2F1721.1%2F59952%2F676953430.pdf&ei=ZYMRU7PaFce5lAX8tYHYCA&usg=AFQjCNGoUbwWCbaXkcdiwv-ivpeAG-uzCg Edited 01/03/14 06:54 AM by Adamfiza80 Link to comment Share on other sites More sharing options...

They did it as the cooler the fuel was the denser it became - eg more fuel in a smaller area.There was probably an advantage injecting the fuel that hard in to the cylinders it doesnt matter about atomisation. However for a normal road car, atomisation of the fuel is more critical for a more homoginious combustion. Honestly, if my last name was Senna, I'd worry about fuel temp. For all other purposes, maybe not 1 Link to comment Share on other sites More sharing options...
