Logic multiple injections Jtdm

[made83]

Hi, I would like feedback on the fact that we have noticed through the diagnostic software on the multijet / jtdm that the pilot injection ceases to exist with the water temperature above 62 degrees and that, as in my case (147 jtdm 16v edc 16 c39 without dpf), not only is never used for the post injection (I think it is useful only in the case of dpf regeneration which my does not have) but not sinpresenta't even have the injection after any situation of use...

after and post injection are the same thing, that means they are injections that avvegono after the main injection, or Main injection..
if your car is not equipped with a dpf is normal that the postiniezione there will never be..
on your multijet, you can have up to 5 injections, namely a pilot injection, a pre-injection and the injection true is relished, indeed, the Main and the two that I said to you before...on the multijet second generation of injections can also be 8...

No, I assure you that the injection to after the post, while being both as you rightly said after that in the main, are two injections distinct. The after should be a few degree (max 15 degrees if I remember well) after the tdc, the post is very over, and that serves only in the phase of regeneration to increase exhaust temperature seen near the beginning of the opening of the exhaust valve. What I was wondering is if you've noticed (like me through the diagnosis, and the pilot is there only to chill and precisely up to 62 degrees of the refrigerant.

We hope You to attach this manual to the Fap where there are explained the injections

In fact, there are post and after separate.

I assume I do the injections associated with the operation of the fap are removed after the luca stanca.
In fact my 147 cold is changed after the luca stanca.

Well, it is a pleasure

when I wrote that post, and after were the same thing, I was referring to the fact that either the injections, however, occur after tdc...so for me after and post however you want to call are post injections which are not needed will go a diesel loud indeed when you process heavily a diesel you try to avoid going into the post-combustion chamber.
