'I have noticed that most internal combustion engines seem to run more
smoothly in very wet weather, assuming there are no wiring concerns and that
the engine is fully warmed up, but this could be another issue altogether.'
So have I, particularly in absolute downpours where the rain hitting the
gound litterly sucks the temperature down by evaporation and the ater is not
necessarly held as vapour but as fine droplets. Just at this point they seem
to have the ability to radically alter the combustion process, as I have a
job believing that the whole effect is solely due to reduced inlet temps and
the consequent higher charge mass. Shall we synthesise our 'intuitive'
experiences here? Simply injecting water into the inlet without thinking a
lot about exactly simulating the actual parameters that produce this effect
might be too simple.
