change advances

you say you to es divide the 70mm3 for the 20? degrees of advance practically we 70/20=3,5mm3 for instance?that every 3,5mm3 of diesel I have to increase a degree of the advance? on, I believe, you reduce everything to this simple calculation, elementary...

I'm reminded of sottolinenare a very important concept when calculating the length in degrees of the injection by first converting degrees to minutes, or in degrees per second, you are neglecting the first that the motion of the piston is not ? linear but bens? sine, according to the speed? and the acceleration of the piston depends on the mass of the crank mechanism and its geometry, i.e. stroke bore size of the rod radius of the crank etc..

Hello cicciogsr, up to here I fully agree with you!

for example, to dispose of 10 mm^3 in ir? in theory you need about 2.5 degrees in pi? in advance. the calculation of v? made for all of the rpm at which you change..

? only a theoretical evaluation to understand the relationship between the capacity and the advance

but that aspect ratio or nonsense various??? the advances are to be the mod with the policy, and as mentioned in the past, you must know how to touch them.. if one touches the advances should know what to expect.. can you ? the state also posted a document with valuable attesting to everything I say..
unfortunately, lately, I can't follow so much the forum..but I can give a quick read on what to write.

ok how would you evaluate the advance for inettare instead of 70 mm 80 mm? before I talked about the relationship between iq and advance to understand how they are related in the map ori... I know that can be an ineffective method? d? a basic idea of the data that is read in the map... then many other factors according to which that increase is not allowed? go well, and then needs to be calibrated on the basis of the measurements in order to understand if the increase ? effective ... I was always of the opinion not to touch them ? I have also written...

guys for? if you continue to remain vague, this tread will become the biblical and at the same time you do not understand? how, where and with which policy change that advances....
in the speech f? ciccio then on the correlation between quantity ? advance injection of diesel to fit in a certain length of time find it very pertitente but without specific indications of the case and how to speak of the more or less...
ergo you will never no...

I tried to give you an idea of how to find a method that is appropriate modification, only by tying two sizes...

since you do not want to make any test for me we can close here

obviously everyone knows how to do it ,to me, to change this parameter....
