doubt for maps SOI,EOI and injection times

[sportknight]

guys,I have a small doubt on this thing

if I change the maps soi on edc16 on vw it also elongates the time of the injection,then in theory it would also change the timing of injection, or am I wrong?

if instead I change the maps soi on edc16 common rail injection time is anticipated, and then the injected ends before,right?

at this point, the EOI to serve if good or bad in the beginning to me the advance and the end of the from the time of injection?

[marcusmagic]

Unlike classical systems, the Common Rail provides for the generation of pressure
is decoupled with respect to the injection: there? means that the pressure is generated
regardless of the number of turns and the amount? fuel and pu? be
selected within a predetermined range (currently from 150 to 1800 bar). The
the component that makes possible the decoupling ? the accumulator high pressure;
the injectors are opening controlled electrically by a solenoid valve. The system ? managed
completely electronically and allows for the generation of multiple injections (pilot,
management of post-injection).

[sportknight]

then sorry,the injection times manage the time of each injected?
the advances would be the soi and manage the pilot injection?
the eoi manage the post-injected?

[marcusmagic]

it is just so..:) for the post-injection means injecting after the outbreak!!!

[sportknight]

and the main injection that is managed?

[marcusmagic]

but from what aspect?? in the map?? I have in the motor circuit?? try to be more precise, thanks :)

[sportknight]

always map speak :)

[marcusmagic]

the main injection is handled by the map type 16x20 grommet 16x16 16x24 20x20, etc, etc, then it also depends on the map!! there are a couple of maps that manage the main injection!!

[sportknight]

I know that if I do not put a map we do not understand :D

to 1D0620 I see the first map in advance
to 1D0864 the second
to 1D0AA8 the third
to 1D0CEC the fourth
to 1D0F30 the fifth

then these other two should be the eoi
1D1FDC
1D2220
1D2464
1D26A8
1D28EC

[marcusmagic]

you've done well to put the map!!:) cmq is the first addresses are the advances, and all other eoi are absolutely right...
but be careful that you touch ste maps!! usually do not need to touch them, if you do not know how to tap you can make a sea of damage!! eye!!

[sportknight]

usually on advances do a 5%,the eoi not to touch them

look,another thing,between soi and eoi are there other maps in degrees,are the maps to the pilot or what?

[SandroMarciano]

usually on advances do a 5%,the eoi not to touch them
...

advances perhaps of all ? what is pi? wrong mod in percentage! To be modified as required and as needed!

[sportknight]

and how is the cacolo should be changed with the advances?

[SandroMarciano]

In order to keep the end of the injection near the pms

[marcusmagic]

the maps that you know up to now, and those that are modifiable as advances soi and eoi, and the pilot of the degrees you change with the points, not percentage! you may make a mistake depends on the map that you can find,are not all the same unfortunately....

[marcusmagic]

In order to keep the end of the injection near the pms

sandro,please explain better what you mean by close to tdc, and the meaning of pms..thanks...

[marcusmagic]

so who has any doubt unable to understand the whole....:)

[SandroMarciano]

depending on the engine that lies before, if it has the dpf/fap, if the map is a pi? or less boost, etc etc decided to end the injection near (+/- 5?) at tdc (top dead center). you quoto when you say the mistake that you might make...
My 159 at 4000 rpm comes from the original, 40?, if you apply a 5% go to 42?, a little' tantini... (and useless)

[marcusmagic]

it is, in fact, do not need to touch them, so nothing changes! indeed, you can only make a mess for nothing....so ec is always a limit to everything :)

[SandroMarciano]

not ? true that you do not need to touch them, ? mandatory to do it in some cases: I in my jtd injection 100mm^3 of diesel fuel/inj, advances without a pilot ori are calibrated for a deal? 55mm^3, let ori would be a serious error, why? termineresti the injection surely after 10? from pms... consequences: temperatures at the stars, turbine, cooked in a short time, collectors deformed, reduced power, etc, etc

[marcusmagic]

but your machine ?? jtdm? I have a jtd?? safe and a multijet...am I wrong??

[sportknight]

well, to the soi, the 5% would be a difference of 1.22 points on 24,49 that ? the maximum value and that should be the equivalent of half a degree
it seems to me very
then by changing the soi are not going to anticipate the injected but to move it to the pms

in the eoi instead, I read that it can be up to 3 degrees, which are 129 points

I was wondering what the advantages would be to move the eoi? away from eoi from pms cos

[SandroMarciano]

but your machine ?? jtdm? I have a jtd?? safe and a multijet...am I wrong??
I have both mjet jtd is, l? I was referring to a 156 1.9 jtd 115

[marcusmagic]

in theory, moving away from the dead point, but the advantage should be injected much more in advance, but 3 degrees I would risk them...anyway the theory and important, but the experience is far more than that :)

[sportknight]

wait what? I don't understand anything worse than before

the soi maps are those that regulate the preiniettata
if I increase the values, what happens? the map is anticipated or is postponed to the pms?

the maps eoi are those that regulate the post-injected
if you increase the values, what happens? the map is postponed, or closer to tdc?

the maps main instead of in the files that I have attached where are they located?

however, to better understand what we are talking about I attach an example of the injection

3284

[sportknight]

I see that it affects so many,yet ? a topic that should be of interest to

[marcusmagic]

instead, you're right, ? a very interesting topic...if you increase the soi map is anticipated. but remember the post and after the outbreak then it is postponed.....these maps that you are looking for usually are touching even when you're doing dpf off depends on the machine...are the curves on the square on half the map...

[sportknight]

as soon as I arrive home, I search for them :D

then let's see if I understand

if we consider the top dead point, such as 0 we will have that by increasing the map soi(advance) preiniettata you allontanera from 0 as if it were an increase in the negative

[marcusmagic]

exact and proven to do so :)

[marcusmagic]

let me know the test result will give you that...;)

[SandroMarciano]

note that the SOI regulate the advance of the main injection, and then modifying them, however, has no effect on the preiniezione, given that the advance of the latter is given in a relative manner, I make an example:

if the main starts at 20?, the pre-start? 20?+x?.
Anticipating the main 2? this will start? 22, and the pre-to 22?+x?, the value "X" dipender? from another map specially calibrated.

[sportknight]

if the soi and eoi regulate the main injection by modifying the soi and eoi andrei also to change the timing of injection at this point, no?

[sportknight]

what I wanted to say ?

if I do I change the soi and eoi together at this point allunghero it can also be injected as if modificassi the time of injection?

[SandroMarciano]

I think, but I'm not sure that the soi are related to the main, while the eoi at the beginning of the postiniezioni, the file never ? determined solely by the duration, and I'm pretty sure!

[sportknight]

a,here we go,then the eoi should anticipate all of the injected while the eoi should give the end of the postiniettata(the beginning depends on the time of injection)

[sportknight]

alora,I studied a bit the damos of edc16c39 mounted on fiat group 1.9

the maps soi are these that I listed already? before

to 1D0620 I see the first map in advance
to 1D0864 the second
to 1D0AA8 the third
to 1D0CEC the fourth
to 1D0F30 the fifth

these are no other than those in regeneration
1D1FDC
1D2220
1D2464
1D26A8
1D28EC

at this point I think that the eoi in the real world? does not exist why? depart from a certain angle to date other maps(but moved from the down payment) and end when the injection times say that they have to finish



right?

I think that the eoi can be related to the angle of the beginning of the post-injections, which I think that are only enabled during regeneration.

[sportknight]

I have been searching all over the map, but I did not find,tonight maybe looking better,I noticed that there were of the descriptors that I called pre post main etc.. so I think that really is? those give the right position of that type of fuel injection in the engine cycle,with the advances in these maps, we can anticipate or postpone

in the damos called both the soi that the eoi(which we do) soe start of energising,so here's why? I believe that they are the same thing only that the latter refers to the advance during the regeneration...

[SandroMarciano]

The damos anyway ? all but complete, it's missing a lot of things!

[sportknight]

I know,but I think that at least the things that we are complete
