No he didn't. Nobody ever said the CPS wasn't connected where did that come from. Like I said they replaced his IMPERFECT new flywheel and the problems go away the problem is a faulty flywheel not the car.

 

reading comprehension and connecting the dots are not your strong suit...

...disingenuousness you got.

 

Hey, loudbang, here's a soapbox for you to strut your stuff.

What are the 4 reasons that a flywheel is "imperfect" ?

PS that comes from one of my students in engine design; pretty sharp kid. you'll need to be sharp to answer him.


So not getting answer in 48 hours, here's the proper answer:
1. incorrect mounting, generally imperfect al;ugnment or flexible construction.
2. wrong material, generally too weak for service rpm limits
3. incorrect balance, weight distribution or location
4.too little weight or diameter, generally too little or too small radius.
Typically a reduction of more than 20% is likely to lead to problems with erratic rotation. And often overlooked is the 'torque' of the flywheel; to overcome the 'hammering' of the combustion there has to be enough weight at a given radius, 'torque', to smooth out the engine rpm enough to steady the crankshaft rpm (regardless of how its measured accurately)
so the control system (regardless of electronic or mechanical ) can react correctly to the combustion requirements. Generally, the weight can be reduced as the minimum rpm reduces. Once above 3500 rpm a flywheel is likely unecessary.

 

Just out of curiosity, loudbang, just what constitutes a 'faulty' flywheel ?

That comes from one of my students. He's a "A' student so you better get your stuff together, he's a crouching tiger. I know from experience in our class debates.

 

Who with a GE is running an aftermarket flywheel and not triggering any codes? Serious question.

 

That is simple and if your "student" was any good he should have known that is one "THAT CAUSES THE PROBLEMS THE OP IS HAVING." There now wasn't that simple

 

Let me qualify that for you slow guys. Simply replacing the flywheel with a non-faulty one should cause no sensor problems. How's that easy enough to understand yet?

 

Ah, yes the 'simple' answer. No loudbang, yours is an answer from the uneducated.
Instead, here is the answer that you should have offered. If you don't know the causes that result in problems with erratic firing when the flywheel is modified you can't correct problems.

My students wish you well anyway.
cheers.

 

 

Well thank your students for helping prove my theory. But I gave the correct answer in this case.

And you still haven't showed why some people can run them with no problems.

ps I corrected the spelling of unnecessary for your students.

 

Now that there is a "learning point" to help refresh your memory the next question for your students should be "is the flywheel and or the crank pulley included in the balance package of an INTERNALLY BALANCED engine?"

And when they answer correctly "no".

Ask them if that is the case how would the new flywheel need to be balanced to match the internally balanced engine? Answer dynamically by itself so it rotates with the very least vibrations possible.

And if it doesn't? Then you have a FAULTY FLYWHEEL.

 

Or it's just too light to do its job as a flywheel...

 

The flywheels only purpose is to create the geared teeth for the starter to engage, and to provide a clutch surface

Most car manufacturers will simply use a heavier crank pulley that has a rubber insulating ring to reduce resonance and vibration.

Believe it or not, removing say 3 pounds from a flywheel has NOWHERE teh similarity of removing 3 pounds from a crank pulley, even if the flywheel weight was removed near the bolts. Keeping weight at the crank is better in all cases, so if you remove weight, remove it from the area furthest away to a connected rotating mass.

Honda did this all over the 80s and 90s. When Honda was using FACTORY flywheels that weighed 11-16 pounds depending on purpose of the vehicle.

Example, the D15Z1 had a 13 pound flywheel, as measured when I removed it from a 68k mile 1992 civic VX. That 1.5 was designed specifically for LOW rpm torque. What 1.5 liter you know created nearly 100 lb-ft at or under midrange rpm?

That flywheel was lightened for response by a very smart guy on the honda designer team.

Go to the average civic DX and LX of smae year, it had the d15b7 engine that made like 10 more horses, but the similar PEAK torque came 2,000 or 2500 rpm LATER

and my 98k mile d15b7 came with a 16 pound flywheel, but it actually ALSO came with a heavier crank pulley.

So honda cut rotating weight in the effort to improve gas mileage.

and guess what? Both motors are ridiculously reliable. It is damn near impossible to kill a honda D series from the late 80s and early 90s. Then some asshole decided there were too many oil galleries in the block and 96+ D series were prone to spinning #4 bearings when an asshole was behind the wheel, or when the owner didnt take care to do regular oil changes. The oil breakdown made it too thin at #4 bearing

 

Then it's a drive plate and not a flywheel. Honda even talks about the torque converter serving the purpose of a flywheel (mahout posted the actual text up thread) since they don't have a separate flywheel.

The crank pulley is much smaller diameter than the flywheel. Removing mass from the flywheel (much father from the axis of rotation than the edge of the crank-pulley) would have greater advantages in terms of saving energy during acceleration. Maybe that's what you said. not sure...

 

Simple then it would be a "faulty flywheel" for this application.

And 13fit gave you correct info that you can't understand.

 

According to you a flywheel isn't necessary to keep from throwing misfire codes. So how is too-light a "faulty flywheel"?

 

Actually, yes, simple but not knowledgeable. Thats why its Archie simple.
When I posted your reply (why did you leave out the items of causes of flywheel failures in the quote above that would have to be checked and solved?) and the class broke up laughing. Keep posting, you're on our comedy show.
Every problem can be described as 'its the thing that doesn't work thats causing the problem' but that doesn't fix anything.
Its now the catch phrase for these guys for everything on the R&R list. I'm sure I'll regret posting it.
Damn, I started saying it. Oh crap. More laughter.
BTW Here's my students collective reply to you:
those who pretend to know are a constant bother to those of us who do know.
cheers.

 

I'm just going to say "moment of inertia" and then let myself out.

 

Where did you come up with this crap? I never said a flywheel isn't necessary to keep from throwing codes let's see your source for that BS like you would say.

And I said a too light flywheel in response to your question.

NEXT

 

I feel for your students with you as a teacher LOL. They only know faulty knowledge that you are teaching them.

And yet still no answers from the peanut galley as to why some people install them and run just fine. AVOIDING the question much?


And still no answer to the internally balanced engine question? LOL you must be cherry picking only the questions you like and not even giving them the WHOLE STORY.
