Hi Dimitris,

Engine exhaust cannot be saturated because it is over 100 Deg C. Only 
pure steam can be considered saturated at 100 deg c and 1 atm.

Engine exhaust will have a saturation temperature that is decided by the 
molar% of H2O in the exhaust.

This is typically around 55 Deg C.

Regards

Shivanand
