George,

One should be very careful with the water diesel engine as the expansion
of water is much higher volume than diesel so when the injector sprays
water into the superheated air a tad too much water and the con rod gets
bent or a tad too much water and it runs but the main bearings get flat
spots after awhile.  One requires extremely accurate water metering to
prevent damage, lean lean lean.  I have not built one of these but in
theory it should work if the water is a fine vapor when injected so the
adiabatic process can complete as long as the cylinder temp doesn't drop
too far and sink the heat from the hot air during the compression
stroke.  normal water doesn't have a flash point like diesel so while
diesel will provide it's own heat during combustion the water needs even
dispersion and fine vapor so the water vapor does not suck out the
heated air energy from cooling.  Preheating the water vapor might also help.

Something to try with a somewhat static RPM cheap generator diesel one
can afford to destroy.
