Increase injection Times: YES, NO, MAYBE

[magi1984]

I appreciate all the responses, thanks to all
I have definitely lightened up the ideas!

Tell us what you think are the ecu that you can do and no

most of the edc15 and edc16 cr tdi

[alfajtd]

as they said in many...
the injection timing can be changed... of course not*******m...
the righteous one who serves and where it is needed... but this ? entirely subjective based on the preparation request...

[franco75]

when you say the ecu to inject the 15%-20% more fuel, you will be in a map to see for that amount? how long to open the injectors.
This map is supposed to represent the flow rate of the injectors as a function of pressure and time.
If we change, lengthening the time, inietteremo more fuel than what is expected.
The ecu thinks the injection of a quantity? and instead they send more.
It seems to me only a good system to reveal a decrease in fuel consumption.

Will the times only in the event of a change to the injectors

[cicciogsr]

if you require a flow rate of diesel fuel for which the time of injection is not ? was calculated, of course, the ecu is not the make? inject ..

[cicciogsr]

? simple there? I mean if you want to enter a search deal? of diesel fuel, for which there are no information of the duration of injection even if you request the ecu does not you do? inject... and vice versa if you alter the timing..

according to me there are compromises,to increase the quantity injected, or is acting on the pressure(and therefore greater pressure at the same time=maggioe quantity), or you can compromise, and stretched a little the time of opening,and then with the same pressure increasing amounts..ultimately I would take toccado a little wntrambi for not putting too much strain with high pressures..

[goku]

this is one of the reasons why you are switching to piezoelectric injectors,the most apertute of shorter duration,while holding constant the rail pressure ..

[bart]

To me you are confusing the ideas...
Found that to increase performance we need to inject more? diesel (in addition to other interventions), to get there? I can think of only 2 solutions: either increase the rail pressure, or increase the opening time of the injectors (or both).
If you don't touch these 2 parameters, how can you introduce more? diesel fuel in the combustion chamber? Just raising limiters?

[bart]

...if you want to know Bart c'? a third way to introduce more diesel in parit? of time of opening the injector ? rail pressure ? the cio? adopt the injectors, and larger in scope....

I know too that you can install the injectors plus, but here we are talking about interventions electronic, not mechanical...

Apart from this, maybe I expressed myself wrong!
My question was: how can you? introducing pi? diesel fuel in the combustion chamber, without lengthening the time of injection or increase the pressure of the rail?
