Understanding the fuel injection

[robert smith]

Could someone direct me to THE definitve thread on understanding the 6.0 fuel injection system, or explain it to me?

I know that the injectors in my fantastic 6.0 are actuated by very high pressure engine oil, but I will admit to not fully understanding this system, why it was chosen, and really what the consensus is regarding it.

As it was quickly discontinued my temptation is to say that it was NOT a good idea but...............

It was not that quickly discontinued as it was used on the 7.3 and the 6.0 but it is really hard on oil viscosity. Most would prefer a comon rail setup as used on the Cummins and the 08 6.4.

Is this why the engine has the rep of shearing oil?

heres one link i found rather helpful, PowerStroke
but more importantly you will find that every diesel from now on will most likely be common rail. I think if you ask anyone they will say they would rather have a common rail motor or P-pumped motor. Common rail provide the most control over the injectors which is is required now for emissions. While a P-pump really has no control over injectors but is still able to make high power just not cleanly. While the powerstroke is just barely able to if even able to break 1000 hp because can't provide the fuel to make it because of the injection system.

powerstrokehelp.com has a few videos on the injection system. informative too. the system was originally designed by cat if i remeber right, and was killed by emmisions tsandards. what's funny is the 6.0 can beat the new emmisions with a dpf setup like the 6.4. I think the 6.0 is still used in the e series vans with a dpf setup.
