This article is almost 30 years old. No one pursued it because there's not a cheap and simple way of getting 2-stroke engine emissions down to an acceptable level.
ICE are far from obsolete, and will be in demand until the day we wring the last drop of petrol from this Earth.
- joecool1029 8y agoPretty much sums it up. Anyways there's better directions for research now like HCCI that should bring petrol engines efficiencies up: https://en.wikipedia.org/wiki/Homogeneous_charge_compression_ignition https://en.wikipedia.org/wiki/Homogeneous_charge_compression...

I don't think it's fair to say no one pursued a more efficient and emissions friendly two-stroke engine. In the boating world, there are examples of modern two-stroke outboard engines which do meet current emission standards. For example, the Evinrude E-TEC range.[1][2] [1] https://www.evinrude.com/en-US/e-tec.html https://www.evinrude.com/en-US/e-tec.html [2] http://www.evinrude.com.au/BuyAnEngine/News/NewEmissionLawsareComing-We.aspx http://www.evinrude.com.au/BuyAnEngine/News/NewEmissionLawsa...
- maxerickson 8y agoThere's some crossover point where synthetic fuels are cheaper than drilling. If energy prices decline with solar, ICE may be in demand forever. I guess probably not for personal vehicles.
- sitkack 8y agoWe will start synthesizing petrol. Organic fuels will be with us for whatever the human race decides is _forever_.
