moist exhaust fumes

[gaede Lurker Find all posts View Profile Close gaede]

This is my first post folks, so please take it easy :}

A friend of mine pointed out that the exhaust fumes produced by my car are 'moist'. I checked if the level of moisture in the fumes changes as I drive the car and noticed that it stays consistent through out a trip. Is this common for prados? I am wondering if my car is running rich...

The moisture is:
of no colour, however if you put your hand in front of the exhaust it quickly gets wet
there is no change in radiator fluid level
even after a 50km+ ride the moisture remains
smells like normal exhaust fumes


any ideas?

Cheers

Water vapour is a product of burning any hydrocarbon. At the temperatures inside the combustion chamber it's purely gaseous, but as the exhaust gas travels along the exhaust it cools. If it cools enough it will form visible vapour i.e. steam. It's always there, but most visible on cold mornings or on startup.

thanks for that, I have checked a few car exhaust fumes and they all seem to be very dry compared to mine.

I guess I am just wondering if all prados are like mine (moist exhaust fumes is a property of the prado exhaust system) or whether mine is running cooler (allowing the moisture to condense back at exhaust exit), richer (compusting more fuel than it should be) etc...

cheers

Rule of thumb for every litre of fuel you burn there is a litre of water out of the exhaust , pretty well due to all the reactions happening from the combustion etc . you didn't say petrol or diesel ?

Catalytic Converter at work...

It uses the titanium inside to convert the emitted hydrocarbons to water.

have a good feel and smell of whats coming out... i agree with everyone else but if your worried youd be able to feel and smell the moisture it will be relatively obvious if you are getting any sort of fuel/oil out your exhaust

I believe that is known as follow-through. Better check your undies.
