Ah, but there is no fuel in the cylinder until the injection pump
"fires" it in! This is the secret of diesels, and the basis of R.
Diesels patents.
Lister cylcle engines use compression ignition by atomizing diesel fuel
into the air and igniting it by compression of the mixture AND a spark,
not by injection, which is why they must be started on gasoline with a
spark ignition. Low compression, to say the least.
Diesels WILL run with a fuel/air mix, but there is no control over the
ignition timing that way. I know at least one person who had a VW
diesel get return holes in the head plugged up, and when the oil filled
the valve cover and spilled over into the intake on the highway had
QUITE a full throttle run until it all burned out....
