Good point. I think Rudy did indeed invent compression ignition. And
the old Ford Proco engine designs were virtually Diesel cycle engines
even though they had spark ignition. In fact, that idea seemed like a
really good one to me, and I would like to know why it never went
anywhere. Was the injection system just to complicated for production?
