you have to see when it reads the value of afr, it will surely be blocked by some limiter. With 0.8, the dpf does not like so much

I don't think there are "limiters" in the classic sense of the term, but rather a "curious" interpretation of the values of lambda, my question was if it was possible to correlate them to the AFR "real" measured from the wideband, chesso', say, for example, add 0.2 to all that you see in the map, lambda and more or less get the actual. clearly if this "0.2" was written somewhere in the map you could be sure that that you do.
But there are also limiters lambda on edc16, on average, the high and fixed to the lambda of 1.25 to a low of 0.6..
As far as the calculation can not calculate "apples and pears"
The calculation is done in one unit of measure.. also calculates that the equivalence ratio of diesel in the edc16 and fixed 0,835 but there are maps that vary the amount of fuel as a function of the temperature of the same..
Some are limiting as that is classic for the only iq are compensation to vary the temperature of diesel..
Perfect, then, however, the values that are normally found in the map are inside this limitation.
from the comment of the overbooster, I thought he meant that "reality" low ones, would not have been actually used.
behold, these I just found, but if you say that there are, I trust, and I try best!
this has left me puzzled.
you may link to "post" you speak of?
the ecu to limit always refers to the couple is a fact, but I don't understand what you mean by "limitation-fix".
by the way I happen I do exactly the same function of the old maps fumes.
if you lower all the values to the flue gas, if we lift not will never be more than a TOT.
I thank you for the answers.
I forgot that the same principle applies to the air to be sucked in that tablet..
He also wrote in the other post that are lambda simulate the ecu does not work in afr function in the strict sense of the term pair-quantity of diesel to the lambda are Of the maps of limitation-fix..
What you say about lambda edc16, and this is just part of the amount of fuel injection of the final in these ecu and extrapolated crude from the map nm-iq, and subsequently "clean" from the map, lambda, and various limiters are scattered in the eprom after that, the ecu knows how long to hold open the injectors to inject X fuel
I try to have my say to see if I have understood the concept. Let's say that you want to have a torque of 400 Nm at 4000 rpm then the map nm-iq revenue the value 83,70 then for a given extrapolated in the rough you want to own this 83,70 mm3 of diesel oil, then clean from the map lambda I want to say that I must search in the map the lambda to the corresponding value for 4000 rpm crossed with the amount of air, because the table stops at 1050,0 and 3750 and it is likely that at 4000 rpm the air intake is already more than 1,05 gr, let's say for example 1,15, the value, however, is that given by that intersection is the last one available and then 1,13. Then I convert the 83,70 mm3 in weight by multiplying by 0,835, and then 69,8895 mg and comparing them with the available air. In the example, 1150 mg of air according to the map the lambda would be sufficient to 1150/(14,7*1,13)=69,23 mg of diesel, so I have to "clean" the 69,8895 and reduce it to 69,23 because the map lamdba me limited to that value.
I know that we speak 2 different languages.
From a former student of Computer science and Engineering, to hear talk of "crude" and "clean" in a microprocessor makes me cringe.
the ecu works with logic, formulas and numbers, accurate at least up to the third decimal place XD
The options are 2, you'll forgive me the bluntness, but are done so:
1) you have the ideas a little confused
2) don't want to say too much because we are in the section of those who should not know anything.
prepondo for the second.
I wish so much that to intervene in someone else's right to give their opinion, not because I do not trust your answers, only that they seem to me, at least, vague.
Thanks again![]()
