Post Combustion injection of water

I stop short of looking into this further due to two reasons:
1) Requires pressure similar to diesel injectors systems - difficult to use a diesel system without causing internal corrosion.
2) H2O2 is not easy to handle.

It is possible to use water only but requires high pressure for good atomisation, droplet size will be the the region of 1-2 microns?

Please do tell us how one can implimenting this concept without massive investment. If you can heat water up you about 300C, you will get some 200 bar of water pressure to work with. The only valve I know to hold thios pressure cheaply is the diesel setup.

Low pressure port injected steam can weaken the bonds. Catalysis can be in the combustion chamber.
Sorry old thread where's Willy?
