Bad mpg?

[Antonm]

Is this what you want to go with?

Ok...

1) 5.3 towing uphill at 80% throttle WILL NOT BE AT 14.7 no matter how many times you try to type this out. The 5,3 will be deep into fuel enrichment (depending on gear) and close to max power so there is no feasible way you can claim it is at 14.7 afr.

Ergo of course it will make more power than a 6.2 that is on flat ground cruising.

2) 5.3 L cylinder mixed at 14.7 air/ratio will make less power than a 6.2L cylinder at 14.7 afr because the smaller cylinder will have less fuel in it.


From 1 and 2 you can see that at part loads (where a 6.2 can be at a higher afr) it will have incremental efficiency over 5.3. The 5.3 has a small enough displacement difference that it will need more fuel to make same power as 6.2.

If this isn't the case, then there is no need to have higher displacement engines.

If every engine on earth that runs on Otto cycle makes the same power at every AFR, or at 14.7, then it must be an illusion when dyno sheets show that a stock 6.2 makes way more power than a stock 5.3 at wot (13.1 afr).

In your view, no matter what the afr is, the 5.3 and 6.2 should make the same power in virtually all conditions of driving. This is ludicrous beyond what the english language can accurately describe.

You're just trying for anything aren't you, sad little man. You're wrong, just face it.

A 5.3 at 80% throttle will in fact be making more horsepower (at any given afr ,including 14.7) than a 6.2 will be at 20% throttle (at that same given AFR, even if its 14.7).

If that is beyond your comprehension then I'm truly sorry for you mankind. Because that's how we got to where we now have warnings in the owners manuals that say don't drink the contents of the battery.

I'll bet the OP regrets posting this thread.

Why, its good for laugh and entertaining, or at least I'm entertained (although it is probably morally wrong of me to laugh at someone that might be mentally challenged).

Vast majority of mentally challenged people are the nicest people ever. At least that's my experience.
They certainly don't go out of their way to be psychologically / socially challenging / obstinate / obtuse / vexatious / difficult,
and they certainly do NOT deserve to be IGNORED.

Please respond to post 79 as well.

Sure, its just yet another case of you being silly and grasping at straws (all while being clueless I might add).

Post 79 started when I responded to your post 67 about how could the 5.3 and 6.2 get the same fuel milage (see post 67 below)



To which I responded in post #70 as;



To which you now throw in;



So, lol, okay, you never said the same rate.

If they're moving or accelerating at different rates, then its not an apples to apples comparison for fuel milage. Of course it takes more energy to move or accelerate at a faster rate. That what's you call a self evident fact.

Remember how I mentioned you should be taking notes,,, yeah this is another time when those notes would've been helpful to you.

You know, you're absolutely right.

My apologies to any mentally challenged people out there for comparing Blanchard7684 to you,,, you guys/ gals are much nicer.

Please continue living in fantasy land.

You are astonishingly misinformed here.

but at least you are making it clear you think displacement is meaningless.

Well done

 

[Antonm]

lol, you’re a riot man.

So by that comment am I to assume you think a larger displacement 6.2 will make more power at 20% throttle than the smaller displacement 5.3 will at 80% throttle assuming that both engines running at the same afr?

Is that what you’re saying now? Because that sounds like what you’re going for, and would be consistent with that earlier statement you accidentally deleted.
