ORIGINAL: Youtalkingtome I'm telling you this because you always try to make me look bad.I might not post again because of this.You don't like it when someone knows something that you don't and you try to discredit them.I am sick of it! Hi guys! I would let the Taurus mileage debate rest for now and just say I am looking for replicability. I will snoop around a bit and see if I can find any other Tauruses getting similar mileage. If I find some getting mpg in the 40s, I would not consider 51 to be too outlandish. If I don't find any that are even breaking out of the 30s...well, you know. I want to throw out some other thoughts. One reason (actually, a set of reasons) why cars pollute less, in addition to those already mentioned, is improvements in combustion. A lot of research on combustion chamber size, chamber shape, and valve placement has resulted in engines that burn the mixture more efficiently. Fuel injection has played a part in this mixture improvement, too. The air/fuel mixture is now a lot less 'lumpy' than it used to be...or in some cases, deliberately lumpy, but in a very controlled way--all to improve the burning of the fuel in the cylinder. Bob You are partly correct. What you are talking about is 1950s technology.The Hemi head design is what most engines are patterned after and that was put into production in 1951.But was first built by Arden for an overhead valve conversion for the Ford Flatheads from the 1940s.The Hemi design along with High fuel pressure that couldn't be done with a carburator is what is used today.As far as air fuel ratio an internal combustion engine needs I think it is 14.3:1 air fuel mixture to run at its best.Not lean and not rich.That was done with a carburator.But with fuel injection you get high pressure. So it goes back to computerized fuel injection. A higher compression engine like a race engine in a race car can burn fuel cleaner than a passenger car.The reason why high compression isn't used today is the same reason it wasn't used from the begining-1950s.Poor gasoline.In the 1950s-1960s we had good gasoline and high performance cars. We all know what happened in the early 70s.In the 90s they started to build high performance engines again with old and new technology.
