    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 combustion and almost perfect if not exaggerate with the diesel. Or vegetable oil, in fact.

    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

    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.
    For the speech vegetable oil, I tried it out on my old micra 1.5 dci (good soul ) to travel with the mixtures that went to the max 30% of oil with absolutely no mechanical problem and no problem of cold start (outside temperature 0?)
    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.

    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 is not possible to produce
    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!

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

    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..

    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?

    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..
