Automotive How do the accelerator pedal and rpm interact in an internal combustion engine?

AI Thread Summary
The interaction between the accelerator pedal and engine RPM in an internal combustion engine is primarily influenced by air flow and ignition timing. While the compression ratio is generally constant, the air-fuel ratio and ignition rate vary with RPM. As the accelerator pedal is pressed, it opens the throttle, allowing more air into the engine, which increases RPM. The air-fuel mixture must be adjusted to maintain optimal performance, particularly as RPM increases. Understanding these relationships is crucial for comprehending engine dynamics and performance optimization.

Exactly, that is what I'm saying

The alteration in AFR is never meant to accelerate the gasoline engine normaly throw the accelerator pedal

The proof is meant pecisely for the linkage between the accelerator and a FEUL PUMP in a gasoline engine in particular as Balucore has claimed rather that just discribing an AFR device

I've tried enough to produce proof. Let's see if any other person can provide more valuable, plausible and satisfactory proof.
Hope you get answers (proofs) to your questions.:smile:

This thread is in some serious need of moderation. May be easier to close it and start again with a better defined scope.

Quite how this has spiralled to a hundered posts ill never know.

It's got to the point where I have no idea what is going on. As the OP seems to have concluded things that are the exact opposite of what people said.

I do understand the subject very well indeed. I just don't see the point of a reductionist classification that demands some things to be more fixed and some things to be more variable. The world is not that simple, as you may now be beginning to realize since you have written;
Yes it is not simple, and nothing is absolutly constant in universe not even the quantaties we have described here, but when you can define the more affecting factors which in this case are the variables, then, you know where to concentrate the most and make your modifications more effecient

Si in this case anyone who needed to tune his engine up for better performance and thought that he better start with adding more fuel to alter the AFR all the time, I suppose that after reading this thread his focus should be directed solely towards the volumetric effeciency and should hold the AFR at it's most optimum value without alteration, ofcourse UNLESS he was looking for other qualities other than performance
Then you would never learn anything about the wonderful variability of this universe, nor how to ask a rational question that can actually be answered.
thanks for the notion Baluncore, I understand what you are trying to say

Other than your explanation of CR which I have replied to I see nothing wrong with the thread

What THINGS do you refer to ?

Perhaps if you can't understand what has been said at least you can try to express what these points are

Any ways I think I got the answers I was looking for so you are free to start you own thread and state whatever you wish in it
