Which would use less fuel?

[D_Eclipse9916]

Theres good discussion here, but I still dont get why you guys are saying WOT is optimal efficiency. Maybe im missing something, but at WOT your looking at less efficiency then at cruising or idle. WOT has to be less efficient as some of the reason of your car being "rich" at WOT is to help keep the combustion chamber cool.

I may be wrong. To give an example of fuel efficiency I Will give a very simplistic version of what "could" be a way to figure out which one is most "efficient" or which one uses the least amount of fuel, two completely different things.

Lets say we are dealing with one "unit" of gasoline as our starting point to not make it complicated.
At lets say WOT at 2000 rpms. .90 Injector duty, so 90% of a fuel unit that could possibly be pushed through an injector (keeping injector sizes the same between runs) and at 2000 rpms.

So.... 2000x.90x(the amount of time it takes to accelerate from your base speed to targeted speed)

Then lets say.... 4000 rpms x .30 injector duty cycle x amount of time it takes to accelerate at that input.


Now you say, what if the car is running rich or lean causing more or less horsepower? Thats why I used an acceleration time input. So you ignore all other inputs (thats why this is a very simplified equation)

Now I am not a physics major and there are tons of variables within this equation, but I would like some CONSTRUCTIVE not destructive input.

PS- to make this real fun, realize that a turbo doesnt spool at 2000rpm at full throttle but then does as it accelerates through 2500-3000rpm so you not only have a variable injector duty but there is an inverse relation as more fuel enters with less time to accelerate.
