Why HEUI?

I've researched this and haven't found an answer. Why did Ford/Navistar decide to go with HEUI injector systems with the 6.0? What are the benefits of HEUI over a standard common rail system?

There arent any advantages that HEUI has over common rail.

So then does anyone know why Navistar opted for the setup when common rail is seems to be better?

As i understand it, the 6 liter engine had been in Navistars drawing room in the late 90's, and with the success of the 7.3, they figured it would carry over, as well as the vt 365 (i think) had been reliably used in the larger international trucks with great success, but it seems when ford gave them the list of requirements that navistar must meet, the resulting engine was not as good as the vt365 or the 7.3, injector problems, from trying to make it quieter were abundant, etc....as well as the famous HG issues......the technology behind the HEUI is great, and was proven by the 7.3......but the navistar team didn't do a good job of taking the VT365 and modifying it to meet ford's demands....

on a side note, there are a few places where HEUI was better than CR at the time...one was dirty fuel, and two was air in the injector system....HEUI is much more forgiving than CR in regard to these.......and the added benifit of oil pump failure won't toast your engine....it just shuts off......

See above in Red. Also, when the HEUI system first came in a Ford truck in the 7.3's the competition was the mechanical Cummins, and the 6.5 in the Chevy. The injector design simply was carried over.... matter of fact, the 6.0 was on the market with HEUI prior to Cummins putting CR on the 5.9.

HEUI is an excellent system in a lot of ways. I operate heavy equipment (up to an excavator that weighs 106,000 lbs) that uses this system. It works well, and won't trash an engine because the operator decided no to check the oil that day.
