^thank you.

TrueSlide

I edited this part. What I had meant to refer to was the space inside the cylinder, not as much as the actual travel of the piston. I was trying to explain it from the point of view for the piston, not the volume of the cylinder.

^i was trying to point out that since the high compression piston had a higher top it ultimately traveled further. The stroke doesn't in fact change, but the space being compressed does because the piston (even though its such a minute amount) takes up more space in the cylinder...

Does that justify?

I apologize for "misinforming" but for newcomers it's a complex explination that i'm trying to simply explain. If you guy catch errors please let me know (on a pm would be nice) So I can fix it. Keep in mind I never said I'm a guru on this stuff...

engifineer

Sorry htown, but you are incorrect. The ENTIRE section on detonation was false from every concept. Nothing about it was correct and even stated that the knocking was the sound of the piston hitting the valve. That is not a mistake made from making it "simple", it is a mistake made because he did not know the information. So I was not out of line for correcting him. Sorry, I just believe that anything that people want stickied should be correct to begin with. But hey... whatever floats your boat.

engifineer

And TrueSlide, I wasnt bashing you for taking the time to write up the thread, that is apreciated. But you and I both knew that you were missing on the concepts, thus posted incorrect info. I really dont mean to bash you for not knowing it either. But everyone that didnt know any better was wanting put this up as a sticky, when it would have just spread more misinformation.

Again, sorry if I came off harsh

I have to agree with engifineer - a sticky implies GOOD information, and clearly, some if it's just wrong, if not misleading.
Props for doing it - just do it right and it will be good for people to see.
Don't take it as "you're stupid" take it as constructive criticism that needs tweaking.

^that's how I was taking it. I corrected the information that was incorrect the first time around. I wasn't expecting it to be perfect from the get-go. I knew that some of the more experienced people would put in their two cents and call me on anything that was incorrect.

So I edited the article in the sections pointed out. If it suffices the mods now maybe they'll sticky it as long as it's correct, I too agree with both of you when you say it should be good factual information.

Constructive criticism appreciated and the tweaks were made, and thanks again to those who pointed out errors. I wish there was a way to post this up for mods or more experienced people to review and put in their input and two cents, this way all information could be accurate before being released. I agree with you guys 100%, but you all know it's alot of information to digest and then divulge so less familiar people can understand it.

Thanks guys, if there is anything else you catch let me know so I can correct it. It should be good now.

And we're good engifineer.

Cool, I'll get you a beer.... well, it may get flat after fedex gets it there ... :D

TrueSlide

haha, it's all good. If there's evey a national meet we'll chill there.

Not to ask a stupid question, but is our engine a NON-INTERFERANCE ?

TrueSlide

no. Engifineer corrected that earlier. I believe it uses a timing chain. From my understanding.

SciontCya

2AZFE uses a timing chain.

engifineer

It does have a chain, but it is still non-interference. I believe the only engines since 80 (or maybe even earlier) that toyota has built that were interference were a couple in the late 80's if I am not mistaken, for the corolla. Dont quote me on those exact years and models, but most of thier engines since are non-interference.

Interference just means that if the chain/belt breaks, there is a possibilty of the piston contact the valve due to the timing being off. For example, when the cam stops turning, the furthest open valve will be in the way of the pistons movement.

In a non-interference engine, even a fully open valve is out of the way of the piston, so there is no danger of the piston hitting if the timing chain/belt breaks.

SciontCya

OK, we won't make a sticky with that "questionable" info
