Advance injection 1.3 Mjt - MJD8 vs MJD6

[alxcrs]

With regard to the conversion from us to degrees of rotation, I refer back always to this:

degrees= [rpm/60(r/s) * 360(degrees/s) * Tinj(time in us)] /1000000

Then:

degrees= Duration in us / 1000000

[dariuccio]

then, 1183 (time in Us) / 1000000=0.001183 how many degrees would be?
instead, if we duration * 0.000006 * rpm we
1183*0.000006*5500=39? it seems to me more correct as the calculation
(these are the duration of the original map)

[alxcrs]

And' what I have written I...

In summary:

Degrees = [rpm (revolutions/min) / 60 (to get rpm/sec) * 360 (get degrees/sec) * Tinj (us)] /1000000....

from which [360/60]/1000000=0.000006

then... rpm * Tinj * 0.000006 = degrees

I hope I was more clear.

we said the same things in different ways.
then, according to you ? just the calculation that I have done? the table that I posted ? exact?

[alxcrs]

According to me.... I hope if ever in the intervention of a guru enlighten us....

[dariuccio]

maybe... it would be very interesting

[dariuccio]

according to you then ? correctly calculate the length in degrees of the original map and add the map to advance the difference between the times gold and those mod?

I also like the strategy I avoid tap advances changes are not extreme... If I make a change the more heavy with mechanical ori arrival for a maximum of 2 degrees of advance and always with an eye to diagnosis and personal feelings!
In the case of the mechanical changes of the type of fairy turbine, then the discussion changes, and come into the game too many factors to say that there is a strategy unique...
According to me the difference between the times ori and mod can be considered as indicative but not mathematically exact... that is' not' said that if there are 20 degrees of difference in the duration must anticipate additional 20 degrees...!!!!

[dariuccio]

instead, I think the opposite:
the original map, however, still has a mathematical logic to ensure that the injection takes place at the exact moment, and if the injection lasts tot degrees in va early
same number of degrees to make it finish at the same point as the original, this is theory but ? obvious that may not be so.
anyway ? very nice to exchange opinions with you

Thanks... I try to study and learn as much as possible, and surely the exchange of ideas, opinions and experiences is a fundamental...!!!!
