LPG fuel around the world...

[Phil Waterman]

Don't know about the rest of the world but I suspect that LPG may become the only practical answer for antique cars in the US. Though I can find no documentation for it I suspect that gasoline in the US is moving toward a blend that will only work with fuel injection. There have been a number of attempts over the years to get all the old POLUTING cars off the road, regulatory attempts such as requiring all vehicles (regardless of age) to pass the pollution test etc.

If you think that they would just change the blend so that it will not work in a carburetor just think about. The change the blend taking out lead as a valve lubricant, started adding alcohol to the point where it will eat fuel system rubber parts, change the characteristic so that gas burns hotter. All of these things have been done without care for the effect on antique cars.

I was going to ask what the outcome of the Canadian Military experiment was, so thanks Rob for that information. Rob do you know of any detail information about that effort that is available to the public.

So looking at LPG as an alternative is very logical. At one point Toyota had a LPG system for their industrial engines similar to the Chevy 6, so I think there are alternatives the question is going to be matching the RPM and Torque Curves along with the CFM flows.
