SVO WVO DIESEL Heater Exchanger Kit- before Inj.-pump

[rayf3262]

what about capturing the already warmed diesel back from the return fuel tube...?

OK Ditchmeister, I confess, I wasn't looking and thought the glowplug was the second set of pipes. Duh. OK? :doh :lol:lol:lol

But personally I wouldn't run one of these....as Rick says, its drawing a lot of current....if they HAVE to be used, the ones with the two sets of pipework that work as I described above, i.e. the cooling circuit takes over the job of the glowplug when its reaches operating temperature, are the best variety.

But I'd still say (i) if you are only running 50/50 you don't need this gubbins, and (ii) if you must, I'd go for the Peugeot heated filter gubbins to replace your existing filter setup - I've seen one and they look easily adaptable....available at your nearest scrapper for mere shekels, oi vay....

Air will be the problem here unless you put it through a fuel to fuel heat exchanger, probably not worth the effort, Rick

jeezz Briggie, whats that all about? to find the amps youre going to bung through the wire you simply divide the wattage of the appliance by the voltage suplied............simples Not a lot else to worry about on an installation where the longest bit of wire will be about 2 foot

As far as the current draw goes, I suspect there's something out on the maths or the bigger electrical picture. I never ever saw any impact on the engine/electrical system when it was clicking in and out. So what if it uses a few wiggly amps :nenau also think of it like a heated rear window , once its warmed up it doesnt have to come back on for ages. You will find the block stays very hot for quite some time. On a couple of occasions I wa convinced it wasnt working but a burnt finger tip quickly showed me it was hot enough maintaing that heat whilst keeping it away from melting things is why I was on about the ali mounting bracket :thumb2

As for the other points and a flaw in this unit, it is a budget one. It is meant to be used to supplement a water/electric heated one not used in isolation although it can be. The others are significantly more expensive, heated filters are into the hundreds if my recollection is correct.

As far as mix goes? well never measured it scientifically but I worked on the basis that the thinner and warmer the oil mix going in the better all round for reasons well discussed elsewhere. Effectively as soon as you show the tescos carton to the fuel filler cap youre thickening up the normal diesel mix so start doing something about thinning it :thumb2

Its a larf though isnt it

exactly what i said above daved lol :lol

 

[briggie]

P= I x v

I =P divided by v

v= p divided by i

phhhhhhhhhhhhhewwwwww after all this reading my brain is dead and really confused.....so is it even worth fitting this yoke or not, i remember just a few months ago we had the coldest weather in many of a year so i thought be ideal to fit and have a override switch in the vehicle to use only in the winter.

daved if you think its worth to fit i would be thankful for a diagram.

not all of it you didnt , you never burnt your finger on mine as far as I know :naughty no need to intro ohms law either.

Talking to a physics teacher a bit back he said the worst thing you can do is draw the triangle without explaining it because its a short cut or reminder once you have the basic understanding ie p actually means in this case watts and I means Amps . he taught me ahemmm many years ago and I remember it so his theory must have some truth in it :thumb2

it worth it in my opinion. thats all it is mind, my opinion, there'll always be controversy around running on svo and what the ups and downs are because there hasnt really been any definitive scientific research dont that Ive seen. I did shed loads of research though before i fitted it. Bit of a cynic at heart and as an ex (are you ever really?) engineer I like to know the ins and outs of everything that gets fitted to my car, especially after reading one account where someone fastened one of these into his car flat against part of his wiring loom guess what happened when it warmed up properly :doh:lol:lol:lol:lol

Dont forget what Mr diesel actually designed his original engine to run on :thumb2

I'll sort out a diagram later today :thumbs

 

[briggie]

from memory the equation used is .

p ( measured in watts ) ... is i ( measured in amps ) multiplied by v ( measured in volts


p=i x v

:thumb2

my point exactly, needs explanation and the ohms triangle is not needed to work out the current draw on this occasion in fact drawing a triangle confuses the issue without a proper explanation :doh

Poor iceman has already said his heads wrecked.

i also find s=ut+1/2at(squared) on some occasions but not this one :thumb2

lol , i was a t.l.o /instructor for matsushita ( panasonic /technics ) you are correct , once a engineer always a engineer . somethings seem so simple to us , and it manifests itself in explaining to others sometimes .

kind regards

Dont I know it, when I first started making presentations to large groups of individuals on some specialist subjects (dont consider myself a teacher) I was as nervous as hell and rushed, coupled with using abbreviations and acronyms lets just say i got plenty of feedback

which included


"KISS" or as one of our bosses says "Janet and John"


Lesson learnt!

ive had " suggestions " which involved physical impossibilities :thumb2


seriously though , i used to get spotty faced kids from college who had passed all their theory , i gave them a board with a fault on , and got blank faces :lol

i terminated one students course once because he thought it was fun to swap a fellow students electrolytic caps around on a op amp power supply..resulting in a big bang when tested and lots of smell /mess

As somone on a tight budget I would have thought you'd appreciate an efficient £20 part (thats already purchased) that works fine as opposed to the rolls royce alternative

which at crucial times ie from cold draws at least the same or more current because its a bigger block to heat up for one thing and has to overcome the intial excessive coldness of the water. Speaking of the water , it still doesnt hold the block to the correct (as in suitable for svo) temperature all of the time and the glow plug(s) will still operate regularly to achieve that.

I think you'll also find that once up and running the draw from the glow plug on a Terranno alternator and beefy battery is quite frankly bugger all to worry about. Been there done that :thumb2

If youre going to shell out for the bigger one you might as well go for the heated filter which works with the water but far more efficiently than one of the blocks and can achieve a consistently suitable temp. But then of course you need either a dual tank system or an electrical heater to operate on diesel or electrically heated oil prior to the water warming up. So there you are back with the leccy one drawing max 20% of generator current (excluding battery power from the equation) or several hundred quids worth of dual tank kit.

All the info and debate is already out there the conclusion really has to be that since Mr Diesels peanut oil running design was effectively highjacked by the petroleum industry to get one of their products used, things have moved away from svo as the main source of fuel and bringing it back again requires compromise in some areas to get it running sweetly, be that drawing extra current or shelling out for more parts :nenau

I have a question? if veg oil is made of veg what's baby oil made of? :augie
