Crower steam expansion stroke for two stroke/rotary engines

[christian everett]

I was interested in whether it might be possible to incorporate a steam expansion power stroke into a two stroke or a rotary engine. The difference would be that unlike the convention Crower six stroke cycle there would be compressed air in the combustion chamber, without some sort of valve system that I can not begin to imagine when the water was injected. Would the compressed air interfere with the vaporization of the injected water or would the vaporization proceed normally.

It would be highly advantageous to use steam expansion as the means of regulating engine temperature, especially for rotary engines.

What do you think that the main design features of a practical engine would be ?
