"Green" ACVW performance engine?
 

Since we live in a time of climate changes and rising oil prices, I was thinking about the possibilities for a “green” performance ACVW.
Have anyone of you out there done something along the lines of catalytic converters, ethanol fuels (ethanol or E85: 85% ethanol + 15% gas) etc?
Is it at all possible to make an ACVW engine reasonably environmentally friendly? Preferably with decent performance/reliability as well?
If so, what type of engine configuration would be suitable?

Please let me know your thoughts on this subject, it would be cool to drive a “green” ACVW! :cool: :D

In what country do you live?

In mine we can get propan (LPG, liquid petroleum gasoline), which is very clean burning and has an octane rating of well over 100 :D
It also costs less than half the cost of petrol/gas, so you get the best of both worlds.
My 1,8 type 4 runs/ran very well on it.

But availability of alternative fuels is the first to consider... :rolleyes:
The aircooled engines usually don't differ much from modern liqued cooled ones regarding the fuel used.

No converter or alternative fuel but this is the only project I know of to shoot for 50 mpg.

The problem with performance A/C engines is that they are cooling-limited, so the tendency is to use excess fuel for cooling during times of high output. This does not do much for emissions!

Even with alternative fuels you will have to run rich to prevent detonation at higher outputs.

You could go really green with this http://www.e-volks.com/about.html
