CM2200 TDC Reference for Pilot and Post Injection Timing

[jfreemanak]

I was hoping to get a little clarification on the TDC Reference for timing. I understand the Absolute setting, but with the Relative, does that mean what ever values are in the table, that is how many degrees before the main injection event begins? Example, pilot has 15 degrees, and main has 20 degrees for the same row an column, so does the pilot start injection 15 degrees before the main event (or 35 degrees absolute)?

What about post injection? Is the relative in regards to when the main injection event begins or ends?

Thanks for any help.

Cheers,

Jared

Yea you are correct. If you have 15* pilot and 10* main, you're sitting at 25* total timing. Post is the same.

Thanks for the reply. Just to clarify on the post injection, when relative is selected, the reference point is the start of the main injection, not the end. Correct?

I guess I'm not sure on that. I always 0 out my post injection. I've never run a post on any truck.

I do the same. I was just curious. Thanks for the knowledge share!
