    and those toroidal instead, how do they work? those that receive electrical impulses. In practice those toroidal should I be having you in my 1.9 tdi. Interesting!!! You never finish learning!

    in broad lines, the injector has a needle inside, and the toroidal coil and a ball of copper wire cross-section and length dedicated immersed in a kind of transparent varnish this is crossed by the current generates a magnetic field which moves the above-mentioned needle

    I few days ago I just saw a picture with all of its parts and there I realized granch?. I had to do the mechanical great... too bad, I would have liked a casino. If you need help in sicily are there.. I would also do for the hobby!

    hello munro correction injectors is used in diagnosis and as already said, must be close to zero i.e. a correzsione say to an optimum around on all four cylinders around 0.30 0.50 mg/cycle diesel....example if a diagnosis is cylinder 1 = -2,00 mg on the cylinder 3=+2,00 mg the cylinder that should not be, and is always in the positive, never the negative in practice the lever to the cylinder 1 for conpensare the cylinder 3 then evaluate where is the fault, if it is an injector, or, for example, a low compression on that cylinder....
    I read it just now alfetta80...meanwhile, I thank you for having clarified precisely what it is about...more specifically to that unit? d measure we are talking about...even if I have to say that the speech mg and more attributable to go vw tdi pd while for the common rail would be better to speak of millimeters cubic..***** unue, this correction that the ecu f? even "hearing" if a cylinder more or less compression it seems to me veeery strange...I think that the engine and its cylinders,one or more, they can also be completely seized,gone,macciulati,etc,etc...but the ecu knows that for a given transient load on the engine,rpm, and whatever else is always the same amount? the injection has to give...the speech correction according to me ? more than a calibration that the ecu f? depending on the code ina injector to a question of the balancing of the cylinders in order to have an engine the more regular as possible...and I read that the ec is able to manage this calibration, the end say,up to a maximum of 30% of the wear and tear of the injectors...everything else, according to my humble opinion are talking to the wind....

    A control unit is able to understand what'? the cylinder that does not go through the speed of rotation of the motor.
    Let's say that this "speed" unable to evaluate it through the sensor of turns

    ..mmmhhh...and then tell me on a perfect engine that st? at 1000 rpm engine with 1 or 2 or all 4 cylinders, which should not be but that always turns to 1000 turns per minute...the ecu as farebe to figure out which cylinder is not v???
    spigamelo please..why? I don't get it....in fact, I didn't know of these unsuspected capacity? diagnostic of the ecu...

    the engine is not running alone...are the injectors that allow it to run at 1000 rpm...
    I don't remember about the diesel but the petrol there are sensors of detonation that you can understand, to the control unit if there are no shots,depending on the intensity? understand also that the cylinder c'? the problem, and then adjusts the fuel mixture....
    in fact, then the diagnosis ? able to tell you exactly which cylinder has a problem...

    based on engine speed,accelerator pedal (for the first two mentioned, ask yourself why after a certain number of engine revolutions can no longer calculate the correction) pressure pipe,injection time(msec indicates and calculates how much time is remaining in the injector open during the phases of injections per cylinder) from here understands that the time of opening more pressure flute(on the basis of the pressure indicates how much diesel ec in the flute and so far as I inject in the early stages of injection indicated in msec etc.
    I will not dwell otherwise ce to write so much
    ps the explanation and a little home-made, but much more' technical
