TD5 and Veg Oil

[Landysteve1975]

My brother in law has a TD5 Disco and would like to know if he can run on Veg Oil?

If so what percentage would be safe and would he need any mods?

[floyd fan]

I dont think you can run TD5 on veg oil, something to do with it being a common rail injection system.

[freelanderPX54]

Unfortunately not. I asked that question on Mud club and the answer seems to be an emphatic no

[Landysteve1975]

As I thought.

I did say this to him but thought I should check.

Thanks

[ROWSI]

How about the TDI 300, can you and if so what is the mixture. Plus for those in the know, how much is a litre of veg oil.

[lynalldiscovery]

Run mine on 10% veg no probs, ran my old 300 on up to 40% before i noticed a power loss over straight diesel, so 25% would be about right.

TD5 is not common rail as all the injection pressure is made in the injector itself.

There was a fella who ran his TD5 Def on 100% veg but cant remember were i read it as it was a while ago.

Fact: Veg oil will go bang if you squeeze it. As does diesel.

However, diesel comes with an inbuilt cleaner and lubricator specifically designed for injectors, pumps and the general care of other engine components and sadly, veg oil doesn't, and it's here where the problems may arise.:rolleyes:
A Top Gear program from some while back ran a Volvo on veg oil after draining the diesel out. They also pointed out the lubricating + cleaning properties of diesel and recommended a mix if 97% veg oil to 3% turps to overcome the problem. The Volvo started and ran well but I don't know for how long this experiment continued. So this may be a starting point but make sure you are aware of the requirements regarding customs and excise and taxes etc.;)


Got to be honest here, I wouldn't risk my 300TDi engine for this but then again..............................I wouldn't fry my chips in diesel either!!!!:D

[floyd fan]

I run my Disco on 50:50, runs a lot smoother and has plenty of power.
Rapeseed oil is £1.67 per 3L bottle from Tesco/Asda.

Is it the Disco 1 in your avatar? How long have you been doing it? do you just put in 40 litres of each at the pump, or what?

I'm not sure you're right there Lynall. The TD5 injector - as I understand it - is piezo electric and that won't generate an awful lot of pressure. The principle is the reverse of a gas stove lighter. When the piezo crystal is struck sharply with the spring hammer, it generates an electric current at a voltage high enough to cause a spark.

Conversely, the TD5 injector crystal is stimulated with an electric current and the crystal distorts proportionately, opening a needle valve and allowing a 'squirt' of fuel to pass into the engine. The quantity being moderated by the length of time the valve is open and how far (I think).

Fuel is present - under enormous pressure - at each injector from the unmoderated HP pump - the common rail. I think I'm right, but Templ4r will probably be along in a bit and slap me around if I'm wrong. :D

How long (how many years) and how many miles have you done running on a 50/50 mixture? Which model Disco do you have? Have you noticed any downside to running on this mixture? When do you put the veg. oil in, after a visit to the garage or before?

[coco]

Been running 200tdi on 100% veg in warm weather 70% in winter for 3 years no probs

change engine oil every 3000 miles

[stabinthedark]

Was looking at the ACEA (European Car Industry Body which set, amongst other things, oil spec standards), came across this report on the use of veg oil.

http://www.acea.be/files/070208%20ACEA%20pure%20vegetable%20oils%20final.pd f

Has put me off thoughts of trying veg oil. I do accept that running a 50/50 mixture will reduce some of the side-effect.

Call me a sceptic - but don't you think that they have a slightly bias opinion on this subject?

It does state 'modern' Diesel engines (but does not define what 'modern' is?
In the 'test' it has no 'control group' ie out of another 110 that ran on Diesel ...the comparison was x% more or less repairs etc......

It could be that the results are actually BETTER for the SVO run vehicles...if normally 100 out of the 110 vehicles needed repair!

It also fails to state the definition of 'repair'....what does this cover? does it count items not related to running on SVO?

Its a naff 'position' statement and not a true independent body report I'm afraid.

Remember the old quote:
There are LIES, DAMN LIES and then there are STATISTICS!:rolleyes:

Hi Roger,
You are way of the mark here.The TD5 engine is a common rail engine, fuel is supplied by a centrifugal pump in the fuel tank. The fuel is recirculated and passes through a filter and then pressure regulator and then to all five injectors via ports in the head and back out to cooler/cleaner and back to the tank. The injection is provided by mechanical means in the form of rockers and cams just like the exhaust/inlet valves. (the td5 has hydraulic tappets for the valves). The piston inside the injector pushes fuel through the jet just like an ordinary injector. Inside the injector there is a spill valve which is controlled by a solenoid which in turn is controlled by the ECU. The spill valve when open allows fuel to return to the fuel tank and when closed allows injection to take place. Length of injection and timing is all controlled by the computer (ecu). This is a simplistic description of how the td5 injection system works, there are much better detailed descriptions elsewhere on the net.
Hope this helps and doesn't confuse.:D

As Jon says, welcome to the forum Richard. You are obviously in the right place, however ...... :rolleyes: Errr, isn't that what I said, in far less detail? I was pointing out to Lynall - in the nicest possible way - that the TD5 is a common rail diesel and that the fuel pressure is not generated in the injector. :D Is the fuel quantity not moderated - under control of the engine ECU - via the piezo electric injector? :)

Hi Roger,
Ther is no high pressure fuel pump on a TD5. The fuel pump is a two stage centrifugal pump, the first stage generates a pressure of only .75 bar where fuel is fed into a micro filter and water separator the second stage feeds the injectors via a pressure regulator at a pressure of only 4 bar this feed is common for all five injectors. High Pressure is developed by mechanical means inside the injector which is required to atomise the fuel. A piezo crystal couldn't possibly achieve this. There is no piezo crystal in a TD5 injector. Like I said before the length and timing of injection is controlled by the ECU closing and opening the spill port via a solenoid on each injector. Incidentally, piezo crystals are used for doing a similar job and that is in inkjet printers. Ink is fed from the reservoir into the print head cavity where the crystal is made to vibrate at such a rate as to cause the ink to expand (boil) and forces it out of the jet ........................................but that's another story for another forum :D

That makes it twice this year ive been right:D

Def not common rail TD5 has enough probs as it is:)

Richard great name!



Richard (aka Lynall)

[lynalldiscovery]

Lifted from Tech section from DOC site



Electronic unit injectors

There are five EUI’s located in the cylinder head (one per cylinder). The ECM controls the operation of each EUI by supplying a voltage to activate its solenoid. The exact timing of this voltage and the calibration coding associated with the EUI’s is explained in the section on the Td5 diesel engine.
The ECM does not simply switch the voltage ‘on’ and ‘off’ to operate the injectors. Instead, it controls the amount of current supplied to each EUI solenoid. It calculates the current requirement using a current/time relationship map stored within the ECM.
The ECM uses a strategy of ‘hit and hold’ when operating the EUI’s. This strategy will initially allow a very large current to flow to the solenoid ‘hit’. This ensures the injector opens very quickly. After approximately 20% of the injection period, the ECM will start to pulse the current supplied to the solenoid ‘hold’. By doing this the overall current consumption of each injector can be reduced and the amount of heat energy generated inside the ECM can be reduced.

[Roger Whittle]

Oh. :rolleyes:


There was me, believing what I'd read elsewhere. :eek:

But ...... even if the 'rail' pressure is only 4 bar ...... it is still common to all five injectors and thus .... common rail, is it not? :rolleyes:

And going back to the original question, does anyone have documentary evidence of running a TD5 on any mixture of vegetable oil/diesel and what were the results? This question has been asked many times on here, but I've never really seen a satisfactory answer, other than; 'I wouldn't - I don't know anything about it.' :D

Roger.

[RichardJG]

Hi Roger,
Here is a much better description on how the td5 injection system works.
http://www.discoveryownersclub.org/tech/td5engine/
I suppose it could be debatable wether it be classed as common rail or not, but it certainly does have a common feed to all injectors. The likes of the volvo diesels are true common rail and do use piezo crystals in their injection design, but not the td5.
Getting back to veggy oil, no one seems to be able to decide. When I first got my td5 I coincidently started filling it up with Sainsburys diesel and occasionally BP, one day while hooking up the caravan with the engine running I noticed that the exhaust smelt very sweet and almost pleasant also after towing the caravan some distance I noticed there wasn't any soot on the front of the van. So am I using a type of veggy diesel or what. The car seems to like it, not noticed any performance loss. And it certainly smells nice. Doesn't smoke either.

Hello,

Have run my 300 Tdi on 100% biodiesel for a year with no problems, the engine runs smoother and is less noisy. I think biodiesel is a little more refined than straight veg oil though. The biodiesel itself provides better lubrication than normal diesel, it also acts as a solvent and removes the black crud that accumulates after using regular diesel for several years.

[Lord Croft]

My brother in law has a TD5 Disco and would like to know if he can run on Veg Oil?

If so what percentage would be safe and would he need any mods?

I don't know about the disco but read my post else where about my Defender TD5 but bare in mind the TD5 Defender engine is designed to run on any ond rubbish and for the army usage. It pre-heats the fuel before it is injected into the cylinders. The Disco engine is totally differant in design (BMW?)

The fuel I brew is filtered down to 5 microns.

Just an addition to my previous entry as there are a frew errors & omissions. I run my TD5 Defender on 100% 2nd generation bio ex-chip oil. I have been doing this since last October with no side efects. I have covered about 11,000 miles. MOT fine.

Sorry to ask, but what is 100% 2nd generation bio ex-chip oil?

Do you know what feedstock the oil is: soya, rapeseed, corn et al?

Do you mix this with standard (pump/mineral) diesel?

Have you covered 11,000 miles on the same system?

Many thanks!

I am interested here whether or not you are using biodiesel.

How long ago was this? Did you think the change in smell was due to the fuel or towing the van? (have you experienced similar without the van or using a different outlet - Shell, Tesco, Esso?)

[RichardJG]

Hi Oxtonvillage,
Hell! this thread's going back some.

Well, I'm still using Sainsburys Diesel, apparently it's City Diesel and my TD5 seems to like it, and like I said it smells nice, it doesn't smoke and it doesn't throw soot all over the front of my caravan when towing. Been using it since just before I first posted on this thread and has shown no ill effects on my car. Incidentally, I've just had my TD5 1st stage tuned at TD5 ALIVE which involved a remap, egr removal and a decat pipe fitted. (yes, strangely my car had a catalyst fitted) What a difference! Pulls like a train now. If you've got a spare 600 quid and you love your disco, go get it done, it's absolutely amazing.

Thanks for the reply. I have a 200tdi - which I don't think can be remapped?

What I mean by 100% 2nd generation is the tank is full of old chip oil converted into biodiesel through the process that seperates the glycerine and other undesireables leaving a very high quality fuel. It can be mixed with 'dino-diesel' but I don't bother.
This is rape seed and or corn oil(maize) but this time of year I do not notice if there is any palm oil included. Only rarely during the winter did I come across palm oil and I was able to put it to the side until the Spring.
Yes I have been using the same system if you mean the same processor and method of conversion.
I purchased the unit from Etruk at Preston who have been extreamly helpful in sorting out any problems that I manage to encounter often!

[Yorkshire90]

I was advised by Bell Auto Services in York NOT to run the TD5 on veg oil/Bio diesel.

Granted, mine is remapped, however a few months before someone had his/her TD5 to Pete for a full set of injectors after doing so..... I dont think I'd run the risk....rather get ripped off by the Government tax! :)

I am interested to know why Bell Autos advise against bio and on what grounds/experience they base there advice?

Etruc run their own vehicles on it and dozens if not hundreds of customers vehicles on 2nd generation bio including very high spec vehicles.

I am having my TD5 chipped shortly and I don't mean chips chipped!!!!!!

Most people recommend against 2nd generation without sufficient knowledge - ring the guys who I have dealt with - they were at Peterbrough show.

Hi Lord Croft
Are you having your vehicle remapped as a result of running on bio diesel.. I am using a Fuel pod system and use WVO. Have you any issues on water or debris in the WVO and how have you found performance, I have noticed a slight drop in power and less MPG but so far no issues.. I am in th eprocess of fitting a pre heater system to the engine to assist in Winter.. Any ideas on improvements would be gratefully received

I am having my vehicle re-mapped because I can't go fast enough! I process the chip oil (WVO) into diesel so there is NO water or debris in it after the process.

I have not noticed any drop in power, on the contary, the noise is reduced and the power is the same. I really notice if I have to put in Dino-diesel - the engine 'rattles' in comparision. There is no need to have any form of pre-heater installed, the heater plugs are quite sufficient for converted WVO.

The secret is to make sure the WVO is fully converted. Too much detail to go into here but if you go to http://www.etruk.com/
you may find some answers. (I am not an employee or benificerie(?) of this company - I just researched them and then met them at the Biofuel Expo last year. I then purchased a unit from them and am extreamly glad that I did!!!!!!! If anyone buys a unit from them, I do not receive commission or anything from them - I just reckon they are a good and honest company who are very helpful.)

Hi Guys,
It seems like Lord Croft is out there ahead on this at the mo.. I have found no issues with the Fuel Pod system and am very happy with all the cheap fuel!! I understand Land Rover are involved with Greenfuels on this system as Prince Charles vehicles are on the bio diesel etc...:biggrin:

Some quick question on this system:
- How many miles have you done using it?
- how long have you run on it?
- what base oil do you use/where do you get your WVO from?
- which one system do you use and how much did it cost?

ta!

[Auto Defender]

So far I have done 1200 miles with no ill effects.. I paid around 2.5k for the Pod.. I use WVO from 3 cafes and one hotel.. I then filter any debris and de water, place WVO into drums and filter it through to the Pod.. Great fun;);)

[JayHoe]

1200 miles isn't much to say anything about it yet.

Just wondered, have you calculated the pay back time on £2500, quite a while.

[Auto Defender]

Not as long as you would think I was doing £250 a month in diesel!!! So will not take too long, but I have also cut my mileage and use my bicycle .. Now getting fit , looking after my pocket and also about to run the heating on it!!
Not bad...:D

[JayHoe]

Don't forget that after 2,500 litres you are supposed to pay tax as well. Good luck though, hope it all works out!

[Lord Croft]

Hi again guys - just thought that I would update you all on my 2nd generation biodiesel.

So far I have done 13750miles using the fuel - Just about all of this time has been on 100% bio. No ill effects whatsoever.

Some of my processes have not been straight forward and even gone wrong - yep even I have made mastakes!!!

TD5 is running very well indeed. So is the old Peugeot 205 diesel. The car preferes to have a tenner's worth of dino diesel in the tank to the rest being bio. The TD5 is happy with total bio. It just means that on these cold days, it is sensible to let the heater plugs warm up for 5 seconds or so prior to starting. I can cope with that.

Current price per ltr = approx 30p/ltr :D

[JayHoe]

I would be interested in the steps you take to actually produce the bio. Where do you get the various chemicals from - aren't some of them extremely hazardous?

Basically, can you give us a run down please!

TIA

[KrisC]

Biodiesel will run in any Diesel vehicle. However because of complex electronics adjustments might have to be made to newer vehicles.
Biodiesel is not only environmentally friendly but is much more lubricating than mineral diesel.
Straight Waste vegetable oil (filtered) can only be used in old indirect injection diesels with Bosch fuel pumps ( +change rubber fuel lines).
Biodiesel can be produced at home. The equipment to produce can be purchased from yorkshiregreenfuels.co.uk at £295 . The ingredients are waste vegetable oil, methanol and lye. Health and safety rules apply as you are dealing with chemicals.
Remember Rudolph Diesel ran his engine on peanut oil!

I use a different system and the company who I bought it from are www.etruk.com/ (http://www.etruk.com/). Although the kit costs more I have to say that the company are fantastically helpful and I would recommend them any time.

Ring them and ask questions. There is no hard sell ever and they will always try to help you if you have problems with a batch or whatever. Based in Preston.

Where are you based? I buy the Methenol for myself and a couple of other guys who make bio locally.

[OneTen Tom]

I've been running my 1999 110 td5 on B100 since May 2008, no modifications needed just changed the fuel filter after the 3rd tank. There seems to be alot of hysteria around biodiesel from increasing food prices to damaging engines..... none of which are true. Don't forget that Rudolf Diesel designed the engine to run on vegetable oil (peanut oil to be precise) and demonstrated it at the World Exhibtion in Paris (1900). True some engines run better with dino diesel, but all diesels should be able to utilise biodiesel. The important factor is the production of the biodiesel....how clean is it and how much water has been removed ( don't forget that dino diesel isn't all the same quality....you pays for what you gets!). There is a european standard : EN14214 for biodiesel to which commercial producers should adhere.

So far my power is unchanged (subjective) my fuel economy has dropped by 1 mpg, the engine runs smoother ( don't confuse viscosity with lubricity) and quieter and I'm producing less CO, CO2, SO2 and particulates. I'm currently living in Norway and can buy biodiesel from commercial producers Statoil and HydroTexaco, though I have used wvo also. Winters hear are severe (-14C today) and I have started from cold and driven at -20C mixing in @ 20% dino with no problems....just let the glow plugs go for an extra 30s or so. There is no need for clumsy fuel preheaters. If you buy wvo then below -5C just add in some dino to prevent sludging.

My advice to anyone considering trying biodiesel....if your auto is out of warranty....JUST DO IT!! You will only wonder why you didn't do it before. The manufacturers are even coming inline - Porsche have recently carried out a major research program for Mercedes where they conclude that biodiesl actually improves longevity of the engines....10 years from now we will remember these debates rather like the Millenium Bug scare:eek:?

[derbywill]

Hi i work for a hgv garage and the most of the engines i worked albeit alot larger have the same fuel system as the Td5's unit injector (PT fuel system) which it is not a common rail system, a common rail system has a low pressure pump which supplys a high pressure pump, whereas in a unit injection system the high pressure is made in the injector by the force of the camshaft, the electical solinoid on the injector allows the required amount of fuel into the injector around the needle and doesn't control when the fuel is injected, the fuel timing is controlled by the camshaft.

The manufacturer has released a service bulliten about the use of bio diesel and stated that the maximum ratio was 5% bio diesel and various seals have to be changed because bio diesel reacts with rubber differently and the service intervals have to be halved

Hi im new to owning a landrover and have bought the 300tdi first of all doest it have a TD5 engine? and second i want to run mine on veg oil and i have been told to do a 50/50 split by a land rover mechanic and avoid using it in the winter if you can i dont know what to believe as there are so many opinions and so many different ratios of using oil, but it would be great to run it at this point in time as diesel costs, is there anyone out there who has had a 300tdi and has run it on veg. i have herd of alot of ways to do it but what steers me more towards doing it is that i have never herd of any problems maybe you could do it in the winter if you switch to a thinner oil who knows not me?????????

[wytco0]

Hi im new to owning a landrover and have bought the 300tdi first of all doest it have a TD5 engine????

As far as I am aware the 300 can run fine on veg and bio. Its the TD5 that cant.

[Tookie]

Which one is the TD5??

[Charles]

I read a thread on the RR site that on the V 6 diesel they add 500 ml of 2 stroke oil semi synthetic to every fill up and some are achieving good drop in fuel consumption, does anyone know if the TD5 can do the same ?

Regards to all

Charles

[Tookie]

Hi guys just to update you im now using WVO which is filtered to take out all of the bits, i then place it into a 5l container along with 3 quarters of a pint of white spirit to thin the oil down, a friend from landrover recomended this as he has done it for about 10 year, i asked him about the TD5 models and he said its a big no no as something to do with inline something ha ha i dont know but he said i cant really be done, mine also has the bosh pump and i carry spare fuel filters just incase, it smells like last nights bbq on start up but has now done over 100 mile with the veg oil in and everything is running fine, quieter engine and a little more responsive to the pedal but i here you may loose off the top end, who cares.......
