Engine bay filter

[Tony]

I call this the WTF (Wax Trap Filter)



Did me for a two hour round journey - with lots of PTFE!  Yes, those are 15mm isolation valves...

Now permanently installed in the engine bay (with the right fittings and a little bracket).  I'll take some new photos tomorrow

there was a guy on the noname site selling half size car kits for fuel filters 5 inch jobbies, ok if you got the room, im well happy with my sausage filter buy 5x off the bay of E for roughly £12 so ont even bother claning them just throw away ( although nver had to clean one )

I suppose your next trick will be raw bio in the tank and on board filtering

[Tony]

It seems that the standard 10" housings are only designed for positive pressure though, that red knobbly bit on top (where the pressure gauge can be fitted?) has a sprung rubber washer sealing it against the inside.  Good against positive pressure but bad with vacuum.  I've had to remove it as put in a self tapper from the outside with a washer underneath it instead.

I've put it next to the rad (only convenient space) and put the course filter somewhere more visible at the top.

Only issue is that there no NRV so it all drains back to the tank when the engine stops, so I'll have to add that.

Won't you get a problem with wind chill mounting it there?

[Tony]

Hopefully not as it's sheltered by the fan cowling. Hadn't thought of that!

[Keef]

Can anything suffer from wind chill if it's at ambient temperature already?

I thought you couldn't lower temps using windchill unless the thing you are chilling is above ambient to start with (eg. warm blooded animals) and you can only lower it to ambient anyway.

[Julian]

I agree with what Keef said plus I thought wind chill was had a lot to do with moisture evaporation, making it "feel" colder.

In the case of the filter, being tucked in a cosy little corner of the engine bay absorbing some of the engines heat must be far preferable to a stream of outside air.

"For inanimate objects, the effect of wind chill is to reduce any warmer objects to the ambient temperature more quickly. It cannot, however, reduce the temperature of these objects below the ambient temperature, no matter how great the wind velocity."

i know when you stick ya hand a out a car window going along it gets pretty dam cold more the faster you go.

will have to test this out stick a probe out the window after it being ambient temp see if it gets colder, i would say yes

Take a read through this Wiki to understand what goes on with wind chill.

http://en.wikipedia.org/wiki/Wind_chill


With your probe and car experiment it will measure the ambient temperature outside. Ie: colder than the ambient temperature in your car for instance.

This is the key statement in one of your links..

"The rate at which a body loses heat increases due to the wind"

with the car experiment was gonna leave it outside then drive with probe out window to catch windchill

==========================================================

so say something (filter) is at 5c (just enough  to drive on with bio) and not get fats/gelling or whatever the terminolgy is, the wind / speed your mph will lower that 5c to say 0c and create solidifying/gelling bio ?

Do you not believe scientific fact ?

  Clearly the light is not on !
