Of course, alternate fuels won't hurt either. Use GTL fuel (synthesized from natural gas). It contains no sulphur. It has much greater molecular uniformity, excellent lubricity and cetane rating of 70 or better. It might even work better at high RPM (greater than 6000). And I don't see why 87 octane pump gasoline or ethanol or methanol couldn't be used in a common rail compression ignition engine (while using lubricity enhancers, of course); if the charge air is hot enough to ignite diesel fuel, it should be hot enough to ignite alcohol or gasoline.
In summary, heat the fuel to the optimal temperature. Cool the charge air to the optimal temperature. Precisely control fuel injection so as to achieve and maintain optimal (or maximal, as desired) cylinder pressure. Redesign electronic injectors to employ more than one spray pattern. Use alternate fuels that evaporate and burn better.

So, you're saying we need to crack the fuel? Or, the numbers need to be moved around a bit like C10, H18 or something even lower?
......I still don't understand why we here in the US don't just cut Diesel and have 20% Bio. 144,000 BTU's Vs~ 135,000 BTU's? Just guessing here.
Without beaking out the S&P orbital chart, what electron are we trying to capture? It would be far more easy and better for everyone if the fuel were changed for the better. Heck, if they could just find a better way to remove the sulfur without removing the lubricity.:doh:
