My veg oil conversion - update

Saltlick · Nov 27, 2014

Oh balls - you're right there! Not sure where I got 5% from - must have been thinking of something else - its 200:1 ratio - about 350ml TSO to 70L derv runs really well. I add a little more to my veg oil tank.

Crowman, I understand now why you have done such a comprehensive job,
belt and braces and all that.

That said have you considered that all that nice hot veg coming out of the Eberspacher heater has got to heat up about 5kg of steel/ally that is the injection pump, with this in mind is a minuet long enough.
Yes a Bosch VE will tolerate cold veg, but as this is a long term vehicle (with a nice shiny new pump) you may wish to give it a little longer to warm up.

I must say though, it's all been done to a high standard and looks great.

i must say you have done a spot on job there but i like to keep things simple on our svo car i, like you tried all sorts to warm the cold veg, electric heaters/ heat exchangers which is where i found the simplest solution the fuel pipe that runs from the fuel filter to the IP is run over and around the rad a few times i admit the car is starting on cold veg but then it was no matter what system is used as the fuel in the pump is always cold but in a very short time the fuel supplied to the IPis nice and warm.

simple

Why would you start on cold svo?
Also are you talking about running a hard metal pipe to allow heat transfer, or a rubber flexible pipe to allow you to bend/wrap it around the rad? That doesn't make a lot of sense...
It must be horrible to start in the winter...

actually i have no cold starting issues what so ever i winterise my svo and as with any fuel system the fuel in the IP and injectors will always be cold at start up unless you electrically heat them.
8mm copper pipe works a treat

Winterised by extended cold weather settling, Or do you cut it with something?

im using svo straight from the cash n carry i add 5% unleaded can go as high as 10% if needed i mix out of the tank and leave it a few days before putting it in the tank giving it a shake each day

Ah, so not so much winterised SVO as VOWULP then

You are correct - in truth I rarely use the Eberspacher - as you can see from the miles I do its a recreational vehicle.

Almost always I wait until the water has reached 40deg (I have installed a digital reader) and then switch over. At this point thee combustion chambers will be hot and that's the biggest concern for me but you are right the poor old Bosch VE pump will be pretty much stone cold and whilst the oil will be warm it must stress the pump until it all warms up.

In attempting to fit digital regulator I needed to strip away the turbo pipework - this is what a 130,000 mile 200tdi looks like with water injection fitted.......

Isn't that the intake side of the turbo, it's widely excepted that the water is injected post turbo as any water (even misted) should be added after the turbo due to erosion of the turbo compressor blades.

No its the inlet manifold - what may be confusing you (aside of the lack of an impeller) is the turbo waste gate T off is now on the manifold rather than the turbo - it reads boost as it is at the manifold rather than the turbo.

Ah I see now, it was the waste gate T off that through me.

Nice and clean inside.
