The "cylinder" is more than just the portion where combustion occurs, when the piston is at or near top dead center. The portion the article is talking about is the portion that, as I said in my previous post, is exposed to gasoline when the piston is at the bottom of its stroke--as it will be at the end of both the intake and the power strokes in a 4-stroke engine. If the mixture is rich, there will be extra gasoline present under those conditions that, according to the article, could dissolve the oil wetting the cylinder walls. That will be the case even if the rings are fine. I just don't think it's anywhere near as significant as the article claims, because, as the poster I responded to pointed out, even if some oil is dissolved in the extra gasoline, it will be replaced as the piston rises again and that portion of the cylinder wall is on the oil side of the rings.
- lazide 4y agoThe cylinder has rings to remove that oil, hence my comment. There should also be very little to no gasoline contacting the cylinder walls at the bottom of the stroke, or at all. The air currents inside rarely directly contact the cylinder walls. If you have any evidence that the effect you’re describing exists, it would be nice if you link to it!
- pdonis 4y agoI don't have any evidence either way, I'm simply trying to get clear about the effect the article is claiming. I am not saying I agree with the article's claims. As I have already said, I don't think the claimed effect would be significant if it exists.
- lazide 4y agoI’m guessing this is the real danger from all the chatgpt like seo crud being generated - lots of ‘maybe, maybe not’ junk generated everywhere that wastes everyone’s time and drowns out useful signal. :( Eventually, what will we be left with? Authority based credibility? Age based? If it isn’t in a 50 year old book directly available via the library of Congress it’s spam? Ugh
