You mean they won't bring back the Chevy Stovebolt's trunk style steel pistons? lol darnit guys. Happy New year! I have some reading an thinking from what you guys have posted. Great thoughts!!

Would you SMokey44211 say that the crevice volume create a area where a quenching action would be created and contain most of the burn in the central crown area?

I would figure tall domes would impede on flow to a point, just curious if deep bowls and motion within the chamber could influence a miss-direction of exiting flow.

Anyone have a thought on how the crown design can affect induction and exhausting processes?

Glad you posted the 2-cycle Tmoose, thank you. I haven't investigated the whole 2-cycle world yet, Pretty kool test piston on page 4. I think I will look into some of that for my bookshelf.

Sorry I left out a word or two in my last post... ......here the heat removal.... by a liquid...is far more efficient than through metal to metal transfer? I noticed Charles Fayette Taylor states with aluminum trunk pistons first quote is apparently for small bore unsuprcharged engines...

Interesting, from how I am interpreting here the heat removal is far more efficient than through metal to metal transfer? I have a old Cummins dump truck piston which is a trunk type. Has the ni-resist top ring land.

Yeah, I am just searching to see whats what Pat. Thanks for posting the Nasa doc Tmoose that will help out my curiousity here. If the oil cooling gallery is crucial for crown cooling, wouldn't the distance from the crown surface to top ring be around the same level of importance as the distance...

Pat, I totally forgot about surface area in general lol dangit. Tmoose, what you are saying, with a forged piece there could be a cast unit (or casting process) with just as well of a heat flow even though that grain structure is tighter in a forged piece or some forgings just dont flow as well...

After having combustion on the mind for a short time again lead me into thinking about pistons and heat transfer and everything else involved. After reading and thinking, the heat distribution of a forged unit will be better than that of a cast unit. I am more interested in the Diesel piston...

Bummer, well thank you for the insight once again. I never came across thought of the reduction in cylinder temps because of the water evaporation, forgot I could compare it to how fuel evaporates within the chamber. I will just stick to drinking the water for now. Seems like quite the ride for...

Interesting stuff, thanks guys for posting. So at 2200 C (3992 F) things begin to seperate, but, we seem to still not be able to use the oxygen molecules coming from water like we would with already consumable air molecules. I am believing that nothing changes between the diesel engine and a...

I know there are a couple threads on this, however I know the reason mainly is to keep things from melting on high power production mills. However, I know the arguement on guys who favor the system and the ones who say you can't make power with water because you can't burn water. I had this...

Tekton, as of this moment I believe we have stressed what we could in the burn improvers here, don't worry about it. You have posted some very informative information. I intend to go through everything covered in the thread again this weekend Turbomotor, thank you for the link! Again, everyone...

The work stock or 2.6 4x4s fuel is only allowed No1 or No2 or Bio with additives albeit no 'oxygen extenders', fumigation systems aren't aloowed or other injection systems either. But, I haven't looked at other classes to see what fuel system and fuels are allowed with Super farm or Prostockers...

Mechanic6, that is another reason I am trying to improve the fuel. USLD needs more lubricity not only to reduce fuel shearing caused on the passage surfaces during the oil's travels to the injector but the injection itself. Viscosity has influence on the injection quality along with lubrication...

Another person I have spoken to mentioned at higher rpms, he thought just the basic Diesel may be beneficial, but with the No.2's lower Cetane rating than No.1, the ignition delay may be too long and miss the point of peak pressure as well as having a less smooth combustion phase due to the...

Thanks Matt, So it would be better to use a non-oxygenated gasoline with a low octane like the basic grade 87? or would it be beneficial to test different grades up to 93 octane etc for mixing with No.2. Since these pumps get turned up, I think we aren't in a lean situation, I would say more...

After doing some reading Mr Gale Banks suggests to leave the Propane for the stove, however he does state that there is a power gain with propane. This particular class is not allowing any fuel systems besides the stock one, but you can build a pump up and use different injectors. Back to my...

I think Gale Banks tried this, not sure if he suceeded though with the hot induction charge. Wouldn't the diesel fuel need to be vaporized in the manifold/port prior to the entrance to the chamber? If we run too high of a boost, or too small of a turbo the heat created doesn't do much besides...
