hi guys,

Im trying to workout a way how water injection into the cylinder can be used to convert the waste heat energy specifically into more useable energy, easily.

try reading about the crower 6 stroke engine and you'll see the angle im trying to get at.

basically, ICE's lose 30% of energy as waste heat out the tailpipes and radiator. how can we get that 30% to do some work?

water expands ~ x1800 by vol when it absorbs heat energy, its latent heat of phase changes is comparatively high. meaning, so long as is doesnt hamper the combustion process itself, it "should" be able to absorb the waste heat energy in the combustion cycle and provide additional pressure energy to the piston similar to a forced induction setup.

an easy way i see of implementing this is trying water injection(NOT METHANOL) into a nicely setup lean burn engine(where all the LB bugs have been worked out).

what do you guys think?
