lots of steam from exhaust Options

[last337]

Why do I have so much steam coming from exhaust? Seems like every time I start it I get lots of water and steam from exhaust. Is this just a function of cold damp weather?

Haha thanks for all the replies. I figured it was normal but I dont understand why there would be more steam from air-cooled engine than water cooled (IMG:style_emoticons/default/confused24.gif)

One of the byproducts of combustion is water

Combustion of Fossil Fuels: The combustion of all fossil fuels follows a very similar reaction:

Fuel (any hydrocarbon source) plus oxygen yields
carbon dioxide and water and energy.



The simple combustion reaction below is given for methane. Gasoline is more complex; however, the results are basically the same.

The combustion of methane means that it is possible to burn it. Chemically, this combustion process consists of a reaction between methane and oxygen in the air. When this reaction takes place, the result is carbon dioxide (CO2), water (H2O), and a great deal of energy. The following reaction represents the combustion of methane:


CH4[g] + 2 O2[g] -> CO2[g] + 2 H2O[g] + energy

One molecule of methane, (the [g] referred to above means it is gaseous form), combined with two oxygen molecules, react to form a carbon dioxide molecule, and two water molecules usually given off as steam or water vapor during the reaction and energy.
