Back about 1962 or 1963 I bought a Popular Mechanics (I think...) magazine and it had a story in it about an experimental engine.
The car or the engine was also on the cover as I recall.
The engine used was a flathead six, the experiment was to do with using extreme cylinder swirl in conjuction with fuel injection to allow the engine to run on a wide range of fuels.
Does anyone have any details on this? The article from the magazine, perhaps? Or even another article from elsewhere?
Even if you remember it and don't have details, please post.
