[WWI] rotaries--2 stroke or 4?

[Douglas Anderson]

I am afraid you have an incorrect assumption; as far as I am aware they were all four-stroke. This doesn't mean that some two-strokes didn't exist. I will be scanning the manuals for these engines from an RFC habd book to our website as soon as I get home. which will definately be before the end of this month.

Part of the problem solved by a rotary was the ignition issue. By passing
past a point of contacts the spark plugs could be fired once on each pass.

For a rotary to be a four stroke there'd have to be a way for the spark plug
to not fire every other pass

Which reminds me, when I get home I will scan and post the RFC manual for
motors.
