Frank you caught that. . .Yeah I'm planning on attaching some very small strips(fins) to the back of the second set of pistons. Not a huge number but a few. We'll see if it helps pull heat out of the cylinder itself and dump it in the crank case(coolant lines run through here as well as oil thats being cooled in a full size radiator). It won't stop melt downs like yesterdays but it might give me an invaluable extra one minute, long enough that I might notice the diagnostics pitching problems and shut it down. I was thinking of putting them on either side of the rod because there shouldn't be anything moving in that area and its attached to the heated body(piston). Understandably its not going to be much hotter than the crank case, unless it, this is hypothetical I don't have any data that indicates this is something that will work or has been done or should work this way, . . .So unless I lose an injector I don't think the pistons going to get hot enough to heat sync(unless the internal reservoir combined with the larger pump cools the crank but is not enough to cool the areas around the cylinders).
Christ, Ideally I would have the injectors in the cylinder. Its crowded and. . . I don't know if its possible. The octane from combustion event to event is probably different because the fuel is not truly homogeneous. Diesel has such a high octane rating. . .whats actually igniting is the air itself(I'm not familiar with diesels so please correct me if wrong) not the diesel. Air itself will ignite on its own once you get a little bit above 500 C pretty reliably, combined with hot cylinder walls and pistons the air will ignite under the temperature(caused by the pressure).
I appreciate the offer for the piston and rods but I'm going to go ahead and bump them to stronger components and aluminum everywhere I can get it. The future of the project is to get this going reliably and then boost it to try and jump on AFRs up in the 60s and I would prefer to only rebuild the engine once(now with ally stronger rods, instead of replacing cylinder 3 now and then coming back in a few months and replacing all of them with better rods and pistons.)
I put my FG/CF layup for the custom on hold. If that engine is going to do this I want it to have every advantage from the get go, whether thats enormous amounts of air venting or what, I plan on building that one to spec for the ultimate performance situation for lean burn.
In the meantime I'm putting everything on hold for the rest of the week. A little tired from engine work lol, and I'll pull Michelle's engine next weekend and start over. Totally open for speculation on how to make it work better or more reliably. Might be till next weekend before I post again ^_^
