The vegetable oil instead of diesel - sure go for it!

[spiki_x]

From the interest shown servant a preview of all of my knowledge on the issue of alternative fuels. Given the price by theft that we are currently at the gas pumps, and very welcome any kind of alternative.

The information will be in parts, because the material and truly vast. Concludero with a tutorial clear and condensed.

To forward the theme I on the plate a historical fact interesting, that has given me the incentive prior to start this adventure:
Rudolf Diesel, the pope of our preferred motor, knew something that we didn't know. Some people have access to information that are igniote to the general public. And the sense of responsibility to create solutions in advance by the problems that will be created in the future.

He knew that come the day in which the price of the mineral oil suprerera any reasonable threshold and will be difficult to afford it. Then he invented an engine that goes on peanut oil! Right. The diesel engine was primatamente intezionato to operate on vegetable oil. Just after they invented the diesel oil as fuel, which was probably a waste in the process of refining.

Of course , when he exhibited his first prototype was mocked, much derided. Perhaps as myself when I was a novice with the fry street.

[danny677]

I would say that secrets there are, are the prejudices of being able to break up and the fear of being caught for "evasion of excise duties on fuels, " that hamper the gesture of throwing in the tank milk oil ( not necessarily peanuts )
Would you like an example ? all engines unijet fiat and Peugeot, as well as? all the tdi the vw group, with fixed geometry turbocharger digest the oil ( including waste provided that it is at least filtered ) without giving any problem if not cold, with temperatures below 10?C approximately.
From 1999 to 2001, I had a marea jtd which I drove 183mila km oil absolute ( often at once ) and scrapped for the incident, a colleague with Ibiza tdi 90cv did 252mila km and still travels..
only thing the smell of fried exhaust that enters your brain.
The engines of the latest generation can not afford it because of the new injectors at risk and clogging of the fap/dpf that you ostruirebbero. Also the turbine variable geometry give problems in a few thousand km by sticking to the palette for fouling, oily and sooty.
No problem with all the diesel chamber but are now extinct..

sorry with the tide I made 183 km in total but oil absolute little + of 60 thousand.

I look forward to more info ( if you have ) on any proceedings abbreviated and less time consuming to separate the glycerin from the oil to create biodiesel as those found in the network for anything affordable as costs and time.

hello

[rts]

I had a customer that put the oil corza in the freelander...40000km and then pump + injectors not ? was a good deal...

[spiki_x]

I knew that you were alive other fryers engines :) Thanks for sharing of experiences.

My adventure started with a golf diesel 87, able to eat everything. It was my company for 3 years with which I have fate 70,000 km oil. The principle was receiving oil from an elementary school, and used directly in the tank, filtering it through by sheer woman. After a while I got bored of it to change the fuel filter every week.
After a lot of research and strokes of genius, I built a real rafineria in campania between the pigs and the chickens. An ideal place for a job so dirty. Believe me, in the process spilling oil all over the place.

To achieve an excellent quality of oil you have to consider the following factors:

- Content of various crap : filter through filter drainage construction. And convenient, and is found in every shop of building materials.
content - aqua : keep the oil above 100 degrees for 10 minutes to evaporate the water from the
- micro filter surface: to filter the oil through the Filter for aqua 5 microni

The result should be a product that is pure and ready to use.

Details follow.

[dariuccio]

but I am in my 1.3 multijet use for about 3 years various types of seed oil diluted with fuel oil (40% oil 60%oil) with a level of care at intervals of approximately 3 weeks, gasoline
(about 2 liters in the mixture mentioned above)? a knock-out.
Then, if we want to make the discourse of consumption... well, saving about 10-15 € per week with an average of 70km per day.
not bad!!!

[danny677]

with 40-60 still have not crossed the threshold limit for the clamping of the injectors, and even why? implement cycles of "dry" with the gasoline.
if you do it on an engine in which the turbine is a variable geometry you would see immediately the blades locked in the span of a few thousand km.
do not exceed 40-60 on the multijet otherwise it will be pain.
on the unijet as said before, no problem even with 100% oil except for cold starts in the winter.

[lukemon79]

This ? my experience: seat ibiza year 2000 1.9 tdi 90 hp rotary vane pump bosch. I went to cooking oil exhausted, filtering it through mainly with a canvas of jeans. I had installed a heater on the flow of diesel, which is heated by the spark igniter dedicated, cold. Hot, he thought about the radiator coolant that passed through this "block" of aluminum, where he was also the fuel.
Scrapped, as danny677, due to an accident, due to an accident. The second I was better with the oil with the diesel. Additivavo with a small percentage of acetone, and would, occasionally, a cleaner injectors in the fuel tank, to be quiet.
However, having a free waste oil, ? still convenient to produce biodiesel for the car of new generation. The only problem ? to know if the tires used in the power system to withstand aggressivit? biodiesel, otherwise it should be changed with the spare parts in a material that ?, the cio? the viton.

[leandro89]

but why? should hang the vanes of the variable geometry? but closing the egr valve does not solve the problem of exhaust gas recirculation? I have read that a machine that is 100% oil pollutes the 98% less than a normal diesel.
the problem for cold-weather starting, just a filter with pre-heating according to me.
anyway, on an engine of the new generation I don't I would never ever cooking oil.
only problem is that putting oil you do not pay the excise duty.

the cooking oil contains lots of glycerin, which, after combustion is deposited together with the soot, creating a sort of tar rubbery blocks the movement of the vanes. If the oil to be refined and separated from the glycerin, it would be ideal to burn in any diesel engine and, for this, as it is called biodiesel.

[leandro89]

but in the vanes of the variable geometry there is exhaust gas or air coming from the filter?

[rts]

The air that comes from the filter and, consequently, with the gas coming from the egr and the sfiatto of the engine and then with residues of oil, amica chips:p

and then closing the egr it solves the problem of variable geometry right?

[spiki_x]

Closing the egr greatly improves the combustion, and then solve the problem in part. There still remains the problem of cold start and smoke; hence at full throttle.
I must also add that the quantity of combustion residues also depends on the quality of oil.
I have had various sources from where predevo the oil and the difference is noted and the like. From the tavern of my village, I took oil of poor quality because it changed every week, and while filtering it through well, you immediately felt the decline in power and increase in the smoke; hence. It was burned bad, very dark color.
Pero from the bakery in the city, I received an oil practically new, given that, because of the quality of the products there were only two rounds of crostole and then changed. And smelled of sweets from the exhaust that was a wonder.

[spiki_x]

I confirm also that the engines are best for this sport are the JTD 100 and 105hp. And it really was the best oil to naphtha. The second choice would be the TDI PD of WV. The system to the injector pump reaches the high pressures (up to 2000bar) that digest everything.
The system is the ultimate for having 100% reliability and ,as already mentioned, the supplied heat exchanger to heat the oil before it enters in the appropriate filter, or you can find filters or attacks for cooling/heating of the fuel. That I saw it on the Passat 4motion.
To completely avoid the inconvenience, I mounted a second tank of a dozen litres for diesel fuel. So I solved the problem of starting in the winters more cold. The car started to oil and when heated to operating temperature, with a switch azionavo the electromagnetic valves connecting the main tank full of oil.
I have used these valves: http://www.jaksa.si/3-way-direct-acting-solenoid-valves.html
The tank I made in stainless steel and mounted under the hood, as in golf, you could dance around the engine. Currently I'm going to make a tank fiber glass custom because adheres perfectly to the place of the spare wheel.

[dvdtuning]

then you say that on a common rail jtd 115hp injectors should be to be blessed, as well as the turbine?

[leandro89]

sar? that I'm wrong, but I think the turbine is not affected, why? if as you say the catalytic converter will also sooner or later it becomes clogged permanently

[spiki_x]

No, The jtd 115 should also go well, because it's almost the same engine. The important is always to ensure good combustion and mixing the oil gradually and see how it behaves. Start with 20-30% of the oil, and do you just have an idea. Furthermore, you can always adapt the program of the control unit, by closing the egr, raising the pressure of the turbine , lowering the misciela (smoke; hence), and raising discreetly the pair.
The catalyst ceases to perform its function immediately after seeing a couple of litres of oil. :) The residues of combustion , and provided with thin deposits on the surface, assessment of the action of the rare earth metals.
The biggest disappointment I encountered was the Vivaro 115 DCI of my father, who metendo 10 litres of oil on a full tank was not more, and you would expect for the road as a lumacha. Sara because of some sensor after the catalytic converter..... boooo. Only after 10 supplies a full and cleaned up and back to normal. So... modern cars do not go.

[spiki_x]

A thought on biodiesel.

Por being a fuel superiorissima quality? for our diesel has problems all his own. And the success that the 5% is mixed in the fuel oil to the european directive, he did break a couple of engines. The official explanation was that they are created of micro-organisms in the fuel and have it ruined. But from the studies I have done are almost sure that you have the wrong recipe. In the process of formation of the biodiesel is used as a catalyst in chemical KOH, which must be removed at the end of the reaction. And here that hangs usually. If the catalyst is not washed from the biodiesel and susceptible to chemical reactions with the water that condenses from the air and form with biodiesel, a kind of soap which of course does not burn and goes to lock the motor. So from this point of view, I feel more safe with the vegetable oil raw, which, with the biodiesel.
Of course, that has even more economy with the oil. Biodiesel costs the same as diesel fuel, or and expensive to produce it.

but what you're saying? are the exhaust gas flowing into the geometry of the turbo!!!!what does the egr? do not write just to write...

[spiki_x]

Perhaps you have not understood the mechanism in question. The recirculation of exhaust gas, and was invented to lower the excess oxygen to decrease the NOx.....
But totally ruin the combustion process by increasing catastrophically the fumostita - then more combustion residues that go to impasticciare the turbine. On euro4 the combustion and damaged so much that the car fumerebbe as a ferry for the EGR, then bisognia munirla of the DPF in order to catch all these smokes.... Then the burn dumping diesel fuel directly into the exhaust..... The result and a diesel that exceeds the rate of consumption of gasoline engines. Congratulations

By removing these technologies***** the burning and almost perfect if you do not exaggerate with the diesel. Or vegetable oil, in fact. :)

[mikyrace82]

I do not agree with absolutely...the egr reinmette in the combustion chamber the exhaust gases, which decrease the amount? mixture useful for the purpose of combustion and the power output, serves to lower the maximum temperatures of the cycle, reducing, in this way, emissions of oxides of nitrogen (NOx), and not the quantity? of oxygen. If you would lower the amount? oxygen then that would increase the fumosit? and not vice versa.

If you dropped the deal? oxygen equal? the amount of? of the mixture is useful then that would increase the fumosit

[spiki_x]

There is not reason to discuss, because both are true statements. The NOx emissions are reduced through the EGR for both effects - the decrease of the temperature of combustion and the reduction of EXCESS oxygen. In truth a hoax does consume more fuel, decreasing the efficiency of the engine.

In fact, more often than not, excluding the egr significantly lowers the fumosit? exhaust (throttle parzialittato and not with the motere at full load since? in queesta particular situation, the egr is closed).
How not to quotarti ;)

However, be careful when you write (I am referring to the discourse of variable geometry) why? you confedere who reads.

I close the ot and go back on topic.
Returning to the discussion of biodiesel: c'? someone who has found a way to produce biodiesel without the use of methanol and caustic soda? Why? I have the impression that it becomes a process much danger with this methodology, not so much for the risk of explosions or fires, but since? the methanol ? highly toxic (risk cecit?) and the caustic soda ? highly corrosive. In conclusion I do not think that is so? sure to produce biodiesel in an artisanal way.

I took the experiment next finch? I have disposed of the vehicle (accident-free), driving along at about 20,000 km, as gi? said without problems.
In the house we also have a focus 1.8! that would be great to be powered by oil, not mixed, but I have perplessit? on the deal? huge carbon deposits that would generate the risk of crusting, pistons, rings, valves, head, and exhaust.

[spiki_x]

To make biodiesel, you need the following ingredients:

- Raw material : Fats, greases, and fats of any type
Here is a lot of freedom of choice, just that it is clean oil without the impurities or aqua
- Replacement glycerin: alcohol - methanol, or ethanol
in theory, and can also use entanolo that is not harmful (if consumed moderately,:)), but it's not possible to produce it
the most pure of 96% through the process of distillation. To completely remove the aqua you would need a "settaccio molecular" that
frankly I don't know how to, and seems to
- catalyst process chimicho: NaOH or KOH
the potassium and the most powerful of the sodium
- Detergent and neutralizer catalyst: aqua demineralized and acid (sulfuric acid or vinegar)

And of course a process that would be a barrel with heating and mixing, and cover not to run off the methanol.

The absence of aqua and essenzale, because understanding the result of the chemical process, and soap. The right dose of a catalyst, but the product after washing becomes mayonnaise!

[lukemon79]

Then I would also add a kit to titration to measure the ph of the oil, to determine the amount? of KOH or NaOH

[camillo]

Maybe he would have problems with a variable geometry turbine such as those mounted on the early models 2,2 HDi PSA where the group palette ? a single piece, and moves in the axial direction to the turbine..

[cronoprima]

guys I have a question from the ignorant. we put the case one is hard to use a mixture of oil and diesel engines with crowd fixed geometry, but unconsciously does not know that in the oil you are microparticles of water, because this molecule is incompressible in the combustion, in the long run will not damage the bands? so I naturally arises the question: is the procedure to heat the oil to 100 for a tot of time to remove the water and should be done always and anyway, no?

[camillo]

to ****l combustion water I think that with the high pressures and high temperatures, its break-up into 2 atoms of hydrogen, which is highly explosive and one of oxygen, good combustion, I think it's more a question of power pumps and ignettori in the problem..

[cronoprima]

camillo I would not insisterti but qnd burn the head gasket, you realize that the water ? incompressible because out water vapour from the exhaust and you get wet the hand, qnd the machine ? hot

[camillo]

All the liquids are incompressible also petrol and diesel, and if buttassi by the bucket load diesel fuel in a home is probably the spegnerei.. I Meant to ****llo humidity, some molecule that is certainly no damage to the combustion, the air is sucked from the filter, especially when it rains a percentage of humidity? the contains surely..

I do not think, however, throw a lot of water from the head gasket, burnt, for the incomprimibilita of the liquid precisely, if the volume of incoming water in the combustion chamber exceeds the volume of the room.. You will break a rod or anything else..

[spiki_x]

The water in the oil used ec! But you have to delete in the refining process. The oil the ricuocevo for 5 minutes above 100 ° c to evaporate all the water.
Quantity minors should remove the filter-separator..... Never had a problem with it, but I have seen the symptoms if there is water in the fuel the engine " bouncing ", at a minimum irregular.

Damage of the madonna is on the engines of the boats. That is the possibility that enters a lot of water in the fuel. A friend has the ancestral home of this experience . He voted down the injectors suffering from this incontinence to overheat the engine.

[anniver]

Up to 50% oil +oil for frying works it smells a little not to the benefit of the motor, but the everything-and-tested opel corsa and goes

[anniver]

According to me better if prepared a aditional it certainly works better

[dariuccio]

? also true that the seed oil will leave a residue in the bodies of power. I have revised my pump rail after having walked for a long time
with the oil of the seeds in the oil ( I used 6 litres of fuel oil, 4 litres of oil and 2 gallons of gasoline) and in the pump, there were solid particles deposited in the passages.
and in any case when an engine burns well, and the catalyst is working properly ? a good sign the water vapor from the exhaust.
I also camillus when he says that all the fluids are incompressible and one sees this type when the gasket burnt I have a injector
that drips when the first engine start of the day, the starter motor fails to turn the engine

[anniver]

Surely the whole thing works but does not burn completely and then brings consequences

[dariuccio]

and in the pump rail what should it burn?
the problem according to me ? with the changes of the temperature, you change the chemical composition of the same and solidifies

[jack91]

Sorry but the gasoline nn hurts to the injectors, common rail diesel?

[dariuccio]

the gasoline ? a good cleaner of the power supply system of course if you exaggerate with the amount? risk of melting the pistons

[jack91]

ah well.. ok and then pi? or less on ke percentage you should put?

[dariuccio]

when the machine is with the fuel warning lamp turned on, I do a 10-euro diesel and 2 litres of petrol.

[jack91]

10 euro is 6 litres anyway, as it says in winmx nn and damaging the gas in the common rail?

[dariuccio]

I use it regularly in my mjet and never have problems

[jack91]

ah ok if you use it in the mjt okay

[anniver]

I said more to emanate the smell of oil, over time, you can incostrare all secialmente with egr turned on
