Anyone hear of this?

Basically one would take a 4 stroke engine, and at the end of the exhaust stroke, spray water into the cylinder, the water flashes to steam and drives the piston down for another power stroke. The big advantage being the use of the enormous amount of waste heat such engines produce. Carrying it further, one would may be able to reduce (or eliminate!) the size of the present cooling system. Downfalls I see are mainly it's use in cold climates (e.g. one leaves their car outside for a week in sub-zero weather, condensation of water in engine components and exhaust system, etc.).
Anyway I just heard of this and recently stumbled across this web site and put the two together. Apologies if it's been discussed already.
