change advances

[franco75]

I'm not good with explanations, but I try:
divide the rpm by 60 to get revolutions per second, and then multiplied by 360 to get the degrees aal second, then divide by 60 and multiply by 360 ?
how to multiply to 6.
had any of the degrees / second multiply by the seconds, and get the degrees.
In the case of the example of mcjtd, or 795 us to 4000 g/m is the duration ? 19?

precisely 19,08?

ok understood, thanks...now let's put the case that we,also, depending on the file posted by ciccio of jtd 105,we have the greatest tinj that ? of 1151us and we have to 1350 bar to press an iq of 70mm3 at 4000 rpm with the maximum advance that ? 21?..ok?
then, the calculation and 4000*6*1151/1000000=27,6 degrees of duration of injection, and as this begins to 21 degrees ppms end to 6.6 degrees dpms....
now assuming that I want to inject 85mm3 to? (radiceq of 1350*1151)/70=604 then 604*85/radiceq 1350=1397us
and then the new duration of injection in degrees sar? 4000*6*1397/1000000=33,5 degrees if I rest with the beginning of the injection to 21? in this case, inquire to inject 12.5? dpms that ? twice as much as expected, the manufacturer then surely I'll fumosit? temperatures and egt to the stars...and then if I wanted to return this value in the standard, I have to anticipate a p? the injection back in my "time window" and return to the 6? in most of the dpms to the ppms also to comply with the percentage of injection of 76/24% based on the pms that mom fiat has decided...

[dvdtuning]

Then you should give 6? of advance?

[munro]

if I want to respect the percentage of injection between before and after tdc, but I believe that you can get off at a rate of 50/50....

[cicciogsr]

6 degrees are so many for me? if you consider the contribution of the turbo for that p? that salt you have to get down

[munro]

you may also be able to? with 12.5? dpms the car to them "digest"... all pu? be...
cos? that even 6? ppms,even if it may sound like a lot,maybe the engine is not "bat an eyelid"....

[Chris156]

the engine digests them easily or almost..but the problem ? that if we were in a perfect world it would be enough to anticipate of 6? and everything would be ok..but no..
the response I have written a post ago.

it would be interesting to know the distribution diagram of the fiat 105 jtd to know precisely how many degrees opens the exhaust valve in this way,according to me,you may continue to inject even after the tdc until the exhaust valve and closed and after this open stop to inject to not finish inettare in the exhaust....

it would be diesel only wasted unnecessarily.
