mustang316 Posted August 21, 2009 Share Posted August 21, 2009 LINK I'm sure one of these universities is going to crack the fuel efficiency nut, it's just knowing which one We are doing lots of cool things at UW, this being one of them. Let me know if you guys have any question about it. Quote Link to comment Share on other sites More sharing options...
BrewfanGRB Posted September 18, 2009 Share Posted September 18, 2009 We are doing lots of cool things at UW, this being one of them. Let me know if you guys have any question about it. I love what UW does--I sure hope it is the one that comes up with the solution. But, alas, my best friend is the engineer, not me. I took a look at the link in jpd80's post and I kind of got the idea...but can you dial it down a little to explain the basic idea of how/what this accomplishes?

Harley Lover Posted September 18, 2009 Share Posted September 18, 2009 The University of Wisconsin concept proposes the use of dual fuel tanks, with port fuel injection of gasoline and direct injection of diesel, with the in-cylinder mixing of the fuels. Mixing ratios vary based on real-time operating conditions. No way. It might work with professional OTR truckers, but the average consumer, who can't even be trusted to change oil at regular intervals? No way.

I took a look at the link in jpd80's post and I kind of got the idea...but can you dial it down a little to explain the basic idea of how/what this accomplishes? We are basically using 2 comercially available fuels to create the optimal "octane" for premixed combustion on the fly. Different rpms and loads require different "octanes" to get stable combustion. So we use a high % of gasoline injected into the intake port (like a current car) and then use a small quantity of diesel as an ignition source. When you do this, the emisisons are very low and engine is very efficient. You can meet EPA limits with no aftertreatment . Also this sytem is very cheap as there is no after treatment and the injection hardware is allready available. Quote Link to comment Share on other sites More sharing options...
jpd80 Posted November 15, 2009 Author Share Posted November 15, 2009 So were talking about PFI gasoline but with a diesel injector for ignition....very interesting. Quote Link to comment Share on other sites More sharing options...
