So from your experience Smokem you insist the vertical wall of the bowl MUST be in place at for any sort of useful combustion huh. I am sure the depth can be questionable however I am not sure if many have thought about the 'fly-cuts' be shaped in a manner to produce a swirling situation to aid in the tumble action that may occur. With that compounding mixing motion could make up for lack of tumble strength keeping fuel evaporation higher, hopefully.
You mention reversal of flame travel could be either perpendicular to the crown or begin at the center under normal conditions. Which would only come about by detonation of the latter situation. I think the thought of mixing fuels to make diesel burn more completely quick, my thought was not that, but that of reducing the heavy molecules within the fuel not a deliberate mixture.
With any alcohol involvement, it should be natural to know the water content could be higher because that is what it does. It absorbs it which is why you must store it properly. Think of the product we use to unfreeze fuel lines, Isohol or HEET. It liquidizes the water and absorbs it. Each fuel has a limit with water content as a basic attribute to produce efficient combustion in our vehicles.
If you run a fuel with alcohol content, the BTU won't be equal, however the standpoint on that is the possibility of what the cooling effect will be on the cylinder and torque output regardless of bow design if the content is large enough. If something is oxidizing at less BTU over a higher rpm the engine will be less stressed, as always the fuel that may be used to racing just may have to be changed to suit rpm needs.
I think the overall weight difference from 5.9 to 6.6L Dmax is what, 200lbs? from factory assembly. If the Duramax platform outruns in combustion innovations, flow capabilities, the old straight-6 just may be left behind just from weight differences.
Thinking something is a stretch, never constitutes it is impossible JQ. Once you get enough instantaneous torque production you can achieve higher revolutions per minute and with that you reached more work being done in the same distance effect our propulsion.
I read something similar to that article CREED, thank you for the link.
