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.

      Hector, 
  What was the ratio of compression again for the water diesel engine?

what ever happened to the water fueled diesel engine ?
