Simplex, when you read:
No electrical apparatus is required for ignition purposes. Ignition is accomplished by its own heat and compression; it runs about 800 revolutions per minute, has five cylinders and no fly-wheel is used.
why do you jump to the conclusion that a (so-called) diesel engine is implied?
A moment's research into early IC engines will tell you that what we now refer to as "hot tube" ignition was widely used and that the engines so equipped were slow-turning. I doubt it would have used kerosene as we now know it, but once running and with the tube up to operating temperature I expect it could have done so.
As I wrote before, I was not going to get involved in this thread which advances a theory, based on a single unverifiable assumption, as truth and why have I even bothered to read this thread.
However you seem to have expanded your argument to include anything you personally don't immediately understand as evidence in favour of your theory.
