If it operates at higher RPMs, that means the crank shaft is spinning faster, and that means that the time interval between sparks in each cylinder would be shorter…
That is pretty much what I had in mind when I made that comment. Thank you for explaining it.
“If it operates at higher RPMs, that means the crank shaft is spinning faster, and that means that the time interval between sparks in each cylinder would be shorter…”…
Well Dah, in any engine that is running faster the time between sparks is shortened.
Well I don’t think your idea is correct but I am no engineer. I know I have driven several V6s and there was no or little vibration. Must be very well balanced.
“rather than the 3 valves in basic engine” how many basic engines have 3 valves ?
The Honda Shadow V-twin has three valves per cylinder. But since it only has two cylinders, it probably only lasts about 10,000 miles. 
"The higher the RPMs the less load on the engine. The higher engine speed helps a lot more than it hurts. The V-6 has to be allowed to run slower or it would eat all the fuel in the world."
Here is a Quote from pleasedodgevan back on page 2 about the 4th post. How ridiculus
“Correct me if I am wrong, but when an engine operates at higher RPMs, doesn’t that shorten the time interval between sparks? This is an extremely elementary concept. Why don’t you get it? Why do you think this idea is so silly?” Ron-man Higher RPMs shortens the time between sparks or firing of any engine whether a 4, 6, 8, or 10. This is irrelevant to the argument.
Would some of you experts out there HELP this poor boy?
He (Whitey) even thinks that they have shortened the interval between sparks on a 4 cylinder engine!!!
…Well Dah, in any engine that is running faster the time between sparks is shortened.
If this is a “well duh!” moment, why did you make such a big deal out of it? You acted as though it wasn’t true, and that Whitey was stupid for suggesting this is one way 4 bangers were made to run smoother, and now you say “Well Dah”? What’s up with that? Are you inhaling paint fumes?
Oh, and who said that high RPMs are good for an engine?
I think it is time to lay off the sauce!
What about his quote is untrue? Please allow me to address each part one at a time.
The higher the RPMs the less load on the engine. The higher engine speed helps a lot more than it hurts.
When you put a car in 4th gear and slow to 10 MPH, what happens to the engine? It gets so overloaded that it starts lugging.
The V-6 has to be allowed to run slower or it would eat all the fuel in the world.
Generally, I think that is true too. When any engine revs at speeds above its optimal range, it uses a lot of fuel. Isn’t that another no-brainer?
Oh, and who said that high RPMs are good for an engine?
Maybe, just maybe, when he said “higher engine speed helps a lot more than it hurts,” he was thinking of helping get more horsepower and torque from a small engine? Maybe he meant it would “help” the engine run smoother? If you think he was saying “high RPMs are good for an engine,” you should ask him what he meant by “helps.”
If we are going to discuss my quote, let’s not pick it apart so some of it can be taken out of context. Here is everything that is relevant:
EllyEllis, didn’t you yourself say that a 4 cylinder engine operates at higher RPMs than a V6? If it operates at higher RPMs, that means the crank shaft is spinning faster, and that means that the time interval between sparks in each cylinder would be shorter, wouldn’t it?
Correct me if I am wrong, but when an engine operates at higher RPMs, doesn’t that shorten the time interval between sparks? This is an extremely elementary concept. Why don’t you get it? Why do you think this idea is so silly?
If any of this is incorrect, all of you should feel free to tell me why. Thank you for your respectful cooperation and for dedicating your time to my education.
Correct me if I am wrong, but when an engine operates at higher RPMs, doesn’t that shorten the time interval between sparks? This is an extremely elementary concept. Why don’t you get it? Why do you think this idea is so silly?
You are absolutely right!! the faster an engine runs the shorter the duration between power strokes. This is extremely elementary. I doubt anyone would dispute that. and the fence posts go by faster too. However, it applies to all engines whether a 1, 2, 3, 4, 5, 6, 8 or 10 cylinder!
Okay, then why does this “poor boy” need help from the “experts out there?”
NOBODY said it only applied to 4 bangers.
well, what does it have to do with anything? It doesn’t help any particular engine. I thot you implied that it made a 4 superior. It is entirely irrelivant! Can someone out there explain this to Ron-man?
It wasn’t irrelevant when I mentioned it. I was explaining my opinion about why today’s four cylinder engines are smoother than four cylinder engines made 30 years ago. Then you mentioned it as if it was totally absurd. Ron-man has explained what I said for you. He apparently explained it so clearly that you now say it doesn’t matter.
[b]To summarize this conversation:
Me: Today’s four cylinder engines are smoother because they have shortened the interval between sparks.
EllyEllis: He even thinks that they have shortened the interval between sparks on a 4 cylinder engine!!!
Ron-Man: Shortening the interval between sparks is just another way to say they increased the optimal RPM range.
EllyEllis: That’s is entirely irrelevant![/b]
EllyEllis, I don’t know what you’re smoking, but maybe you should lay off it for a while.
You acted as though what I said was incorrect. Was it? I would be happy to discuss the merits of this idea if you can conduct yourself in a civilized and thoughtful manner. Can you do that? Can you act like you are more mature than a 12 year old? Do today’s four cylinder cars run smoother than those made 30 years ago? Is it because they operate at higher RPM ranges than those made 30 years ago?
Of course, all engines run better than they did 30 years ago.
It is impossible to shorten the interval between sparks. It is totally absurd!! If they did it would fire before the piston reached top-dead canter. There is 180 degrees between sparks or firing and always has been. (on a 4 cylinder)
A V6 fires every 120 degrees, now that is smoother.
A V9 fires every 90 degrees, now that’s smoother yet.
It was not I who said it did not matter. I never said ANYTHING did not matter.
An engine doe not operate at higher RPMs unless the driver makes it.
What else do you need to know??
If the theory holds, the more cylinders the longer the life.
The other side would be the size and amount of work an engine does. Remember, 6-cylinder semis go a million miles. As do V-8’s…
And, there are 4 and 5 cylinder diesel Mercedes that have been chugging along for 40 years and longer.
Guess the best solution is to stumble onto a great engine and take care of it.
My V6, automatic, Dakota went 623,000 miles.
EllyEllis:
I thot you implied that it made a 4 superior. It is entirely irrelivant!
…I never said ANYTHING did not matter.
You may not be able to spell “irrelevant” (or “thought”), and you may not know what it means, but by definition, something that is irrelevant doesn’t matter.
I thought Ron-Man explained this to you already.
I never said they would shorten the spark time but not change the rotation speed. I said they shortened the interval (interval=time) between sparks, which is just another way to say they increased RPMs. This has already been thoroughly explained to you.
Is it impossible or is it irrelevant? Please make up your mind!
I never said anything about setting the spark to fire at a different rotational position. I don’t know where you got that little gem, but it wasn’t from me.
Interval and time are synonymous. That means they mean the same thing, or they share similar definitions. You have totally misunderstood and twisted my statement into something that doesn’t come close to resembling what I said. I guess if you have to do that to make yourself feel smart, I should not object. You might not be able to maintain an opinion about whether something is irrelevant or impossible, but I will say you are smart anyway. Does that make you feel better?

I think it is a very stupid suggestion.
Are you saying the way to make a 4 banger run smoother is to run it faster?? What about the times when the engine is running slower?
Someone back on the second page of these posts, said high RPMs did more good than harm I think you and Whitey must be drinking from the same bottle!
