ops please forgive me for the error mm2, but mm3,
I wanted to know if 0,85 the map is informed of that value , I ask this because around I read approsimazioni different 0,82 or 0,84 and so on
if it is informed of this value where I read it?.
I know that the values vary little but it is only curiosity.
Also I wanted to know what is the formula for determining the opening time of the injector are read in the map injection .
example in my map of the 147 jtd 16v 140 hp, I read that for injection of 60 mm3/inj with rail pressure of 1200 it takes 920 which formula is used .
thanks a lot for your interventions.
The map works how it should work, the value of 0.85, 0.82 what you think is an artifice our to do the calculations from mg to mm3 and vice versa. If the map is all in mm3 , I don't understand what to go looking in your map
For opening the injector , what you read is the time in microseconds, no formula ... But where the laws on certain things?
In case there is a calculation for calculate the grades according to the time of opening the injectors , degrees after top dead center.
I thought that the map limiter smoke; hence the' so called from the ecm was a iq limiter,
as in the map I read a maximum of 1050 mg of air/(14,7*1,08)= 1050/15,876=66,13 mg diesel fuel or 82,6 mm3 of diesel, but the maximum limit that I can use is about 70 mm3, given that the last bp of the other maps are set to 70, and then bringing ii bp of the other maps to a value of 82,6 max . I could manage 82,6 diesel fuel .
for the time in microseconds was wondering because if I go over 80, are not calculated , ask the case that I want to get to 90 mm3 lquale' at this point the formula in function of the degrees to adapt to the map phase of injection and time of injection.
could you kindly help me?
of course you help
the map of the lambda ( which I don't remember what it's called on edc16) could be a iq limiter, certainly, on-axis has mg of air, but the mV of the probe, so I guess that we are talking about different things, the map smoke with the mg of the air is in edc15.
for the times you can interpolate the difference between 60 and 70, and makes revenue of 10 mm3 in more to make it out of the 80, if you want to go up to 90 multiply by two
To satisfy your curiosity, I will say that the diesel business is subject to a specific call EN590, among the various parameters, the specification requires that the value of the diesel fuel to be in accordance has a density of between 0,820 and 0,845 so in the calculations you may use a value within this range, since you can never know a priori the actual density of the diesel fuel that immetterai in the tank, for simplicity, we can use 0,85 much at the end of the substance changes very little. Personally I prefer to use 0,84 but it is completely irrelevant.
In EDC16c8 there are 4 maps to the addresses 0E9B7A,0E9DBE,0EA006,0EA24A and are the maps lambda and the values contained in them are perfectly identical and in a sense are maps, relief iq as you say. Sincerely believed that the axis would contain the mg, however, is a perfect inexperienced I inquire to those who know more.
If it was, but then again if they were mg, your argument about 82,6 mm3 a row.
Those maps have on one axis the number of rounds that stops at 3750, and let's say the mg to 1050 (in lumens), but at 4000 rpm you may want to read as a mass air flow values over 1100, and then the lambda value would always 1,08 because for values out of scale, we can therefore say 4000 rpm or >1050 takes always the latest available
