Strange fog.....

It was very cold indeed this morning in darkest Kent. I defrosted the Bongo and set off on the school run. After about a mile, we suddenly noticed what at first I thought was smoke drifting around the interior. I screeched to a halt and dragged the children out, then very cautiously investigated. There was no smell, nothing was hot but still there was this foggy stuff drifting about, not seeming to be coming from anywhere. I turned the heating off and restarted the engine and it didn't happen again, so I made an executive decision and carried on to school. No more fog/smoke/vapour. Is it possible that it was fog caused by the warm air from the heating hitting the cold air on the inside of the bongo? Has this happened to anyone else? Any ideas?

Something similar used to happen when I switched the air con on in a company car I once had.
Did you have the air con on? just a thought.

Similar thing happen last thursday going up to Bicester in our Movano truck at 5am near High Wycombe on the M40.
We put it down to the heat of the engine against the very cold air temperature.

Up there again tomorrow (or maybe not if the forecast is right!), will see if it happens again.

My children have decided it was a ghost. Watch out for a dark blue Bongo on the next series of Most Haunted........

Glad it's happened to other people - I wonder if it'll happen tomorrow. Mind you, I hope we're going to have too much snow to go out. What are the chances?

Hydrocarbon fuels contain a small amount of hydrogen which when
combined with oxygen in the burning process, produces H20 which
is water in the form of superheated steam.

Steam is not a visable gas, you can only see it when it condenses
to water vapour, which it does on cold mornings when it leaves the
exhaust system. On warmer days the humidity is generally lower
and can absorb the extra water vapour, wheras when the humidity
is approaching saturation it is less able to do so.
