high voltage injectors (HDi diesel)

[ecoxantia]

I have started a page to document my mpguino for the HDi, under my user at the ecomodder wiki.

Anyone interestged in the HDi engines, or common rail diesels for that matter, might be interested in this paper, which gives more detail than I've seen before on injection maps and so on...

I have now sold my Xantia so won't be working on this anymore.

Thanks, did it work reasonably well or were there some issues? Were you able to get reasonably consistent readouts as compared to the pump?

No, I can't claim it worked that well- but it sure was fun trying!

I didn't have the time to develop it so that it gave a sensible reading under all conditions.

I think there are too many variables to calibrate on this engine; massive variations in fuel pressure, the fuel temperature - varies a lot because of the high pumping pressures, so the density of fuel varies.

I always had a regular jump in injus every few seconds or so as well.

The replacement car has a mpg gauge!

Thanks for your help along the way, I plan to use the arduino hardware for an intelligent grilleblock and temperature indication system now...
