Running a engine in heavy fog?

[Truckie]

I was just wondering what effect a engine would suffer from running in really thick heavy fog?

The only thing I can think of is maybe some rust short life on the exhaust system, and maybe some extra moisture in the oil pan.

This question is not just limited to the Cummins our trucks I'm talking about all engines.

Thanks.

I don't think it will do anything. Some of these guys are dumping TONS of water into these engines with little/no problems. A little water vapor isn't gonna hurt anything.

if i remember right for every gallon of diesel you burn it makes 6 gallons of water. put youre hand by the exhaust and after a bit it will feel wet. fog will have no effect imo

I've been driving in a heavy fog myself the last few years - chalked it up to old age... Yeah, and a few of my joints DO feel a bit rusty...

I always thought that mine ran better in heavy fog because of the air density. The only problem is I can't enjoy it. As far as moisture problems, I am sure that heavy fog is not nearly as destructive as marine applications.

it's no different than driving in the rain.

I've been driving around in a fog for a while now too... chalked it up to joints

I think not. If that were the case there would be floods on the roads everywhere! Diesel combustion does not make water like gas does that I know of. If it does make any it's WAY less then what gas does. Diesel exhaust systems don't rust from the inside out like gassers do. I have never seen a diesel exhaust dripping like the gassers do. You can get moisture from condensation caused by the heating of the exhaust pipe but this is minimal.



As far as driving in fog goes there is no harm that I can think of. You should have more power from the dense air and also from the steam created in the engine.

On a foggy, misty day my truck runs much stronger.

Got a diesel boat and I run in the fog often (that's boating in New England) and it doesn't seem to affect anything.

Gasoline (C8H18) stoichiometric combustion:



2 C8H18 + 25 O2 --> 16 CO2 + 9 H2O





Diesel (C16H34) stoichiometric combustion:



2 C16H34 + 49 O2 --> 32 CO2 + 34 H2O





I'll leave it to others to work out the mol weights - I'm a little short on time right now.
