less oil flow at high RPM ?

 

[JavierH19]

Yep … electric motors taking on the “load” getting the mass in motion …

until you floor it too hard and send it into power mode but the prime is less sensitive as it has more battery. in the reg prius you cant accelerate as hard until the engine kicks which is pretty slow acceleration.

Our Fusion Hybrid is like that …

You wrote what you wrote … that’s not making anything up … and you wrote the same stuff in many posts.
Now you want to cocky because I posted numbers from real vehicles that don’t fit your narrative …
Others can make the same observations …

And you obviously can't understand written words and twist words up to something they are not.

Again, explain to me how how me sayig that cutting back oil flow to save some fuel equates to you concluding: "You have stated that these pumps under delivered oil at critical RPM’s"?

I have never said they "under deliver" oil ... and you've also accused me of "mis-quoting" why VVOPs were used, yet you can't ever prove they are used for anything else beside what I've said that every article about them has said. I think you really must not really understand words (being obtuse) or are just trolling at this point. I though you were "done" with this subject matter, lol.

Would it make you feel better if it was only at lower RPM ... If a regular PD was supplying too much flow at higher RPM (and going into relief) then a VVOP could certainly be designed to reduce it at higher RPM too. For some reason you think just because the oil pressure gauge jumps up when above 3K RPM that it's a "high flow" system. You have zero proof of that because you're not measuring the actual flow rate of oil going into the oiling system.

Maybe you did not get your glasses … let me enlarge

Again ... prove that the flow is the same or more with a VVOP and any RPM on your engine, or any engine for that matter compared to the old PD they replaced. If you want to believe the pumps on your engines are some super pump that flows even more oil than the old PD that was on them, then knock yourself out. Fact is, they exist for the main reasons I've state, and you somehow don't believe that, nor can prove otherwise.

It jumps up on “demand” … it does not follow the same PSI/RPM profile … so what I have said repeatedly is that pressure comes early … that’s only done with volume from that pump stage … I‘m pumping what was your other fear in life … 0W20 at 222F …
As for comments at other RPM - vane pumps are more efficient with thin oils …

Stop worrying about what I believe … I’m on the side of thousands of engines doing fine without you …

"Jumps up on demand" ... that must mean it's automatically a "high flow system", lol.

If the oil pressure never goes above a fixed PSI once the high stage it activated regardless of RPM above that activation point, then the oil flow is being cut-back even at higher RPM.

No doubt you are ... but that's not the focus of the discussion. I'm still waiting for your proof that VVOPs were invented for some other main reason besides fuel savings which you somehow don't believe.

If you go back to my earlier post … that is early flow as the PM software sensed throttle but the mass and RPM are starting to increase …

Boil it down: they have increased HP/torque and MPG … while keeping with emission standards … In doing all that in one engine generation - this is just part of the change.
No need to spread fear about it … not a big deal …

 

[ZeeOSix]

So what does the oil pressure do with increased RPM once it's into the "jumped up" stage? Stay constant or increase slowly ... or ??.

OMG ... "increase MPG". You mean to "save fuel" and decrease emissions like to meet the main goal of CAFE. What a concept. So you do agree. As for increased HP/torque ... guess if you think a 50-100W bump is a noticeable HP gain, then ... I never said they were bad or should be "feared" (more reading between the lines) ... I said I'd just rather not have one (if there was a choice) for the reasons stated. I'd rather keep it simple in the oiling system world.

Maxes out - stays there - and eventually goes to PRV … but the left side of that plateau is early …

Say calm … No, the engine output was increased at the same time … towing capacity up - and it became harder to cool … oil jets added and are one more end users and some are even on solenoids …
In other threads I mentioned my 2010 5.3L did not have them or a cooler …
Pump is really a just two stage for all intents and purposes …

When you get done arm wrestling about VVOP , maybe we can start discussing electronically controlled thermostats.

lol … I was just thinking about that … did not know they snuck that in until we had a bad ground on the old Cruze … now only the Wrangler is hydraulic - but lots of old school Dana in that mix …
