So does that exclude its use if added to the fuel before injection and injected at the normal btdc?Tommy Cookers wrote: ↑Fri Jan 19, 2018 4:05 pm1 the' 'air' intended for combustion' ' contains about 9% water vapour eg at Singapore and about 0% eg at Abu Dhabi
2 an emulsification of fuel and water was said to improve combustion
3 is occasional water injection ahead of the turbine allowed ?
H recovery rate would greatly increase ? but crankshaft power would fall at that time
heat engines have been made eg combining CI and steam cycles

the exhaust pressure will increase if the generator load is increased so that the rpm is unchanged
the crankshaft will do more work scavenging on the exhaust stroke against the increased exhaust pressure
work done by the fresh charge on the crankshaft during induction will be unchanged
so the power delivered by the crankshaft will decrease
direct water injection into the cylinder with the fuel needs thinking about - but my guess is that the rules don't allow it

The combustion process would benefit from extra oxygen in my opinion as not every molecule of fuel is combusted.
