change advances

[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.

[munro]

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.

[munro]

I will say no....according to me nothing is wasted because since when the valve is closed, and you continue to inject in the mass of air and fuel that is burning,already triggered before tdc, and long before the pilot injection, we obtain an increase of the heat and especially the pressure inside the cylinder when the piston st? descending in the stage useful to say this means more pressure on the piston= more torque, ergo more power...
also in the post where calcolavo the advance I forgot to accenare a fact according to me very important to the cio? the pilot injection...
if we put the case with the advance of the main injection, which was 21? we had a pilot injection that preceded this 15? if we anticipate only the main we are going to "accavalarci" the pilot then according to me it would not be affato a bad idea to give the advance of the pilot injection, leaving traquesta and that in the main the same time in degrees that the manufacturer has provided, but "translating everything in advance"

[Chris156]

remember that after a certain number of rounds, the pre-inj not ? the most active.
for the speech to lengthen the injection after the tdc goes well.. but after a certain number of degrees do not need anymore to anything..
you can take as an example a motor in a regeneration phase..

[munro]

but the regeneration of the f? why deliberately injects diesel fuel outside of the combustion chamber...to the point of the post-combustion chamber with the exhaust valve open "charge" of diesel seeds the unburned gas column that st? leaving the engine and then to the end of this burning diesel fuel within the diesel particulate filter to raise the temperature of this and burn all of the particulate matter accumulated in the...what is that ? all diesel fuel wasted....

[cicciogsr]

in previous posts I was with the reasoning of exploit the post-combustion chamber, in the limit of fumosit?
in the jtd the preiniezione ends at about 2800 rpm then starts the main in the mjet ? different there are also 5 injections over the pre
