Hey Guys,
First of all, Wish you a good year ahead ! Hope you all had a pleasant New Year's eve

Now, my question/s

As we all might have noticed that during winters white smoke comes out of the exhaust. Now that smoke is definitely different from a smoke coming out of polluting vehicle. This is purely white & just disappear after few seconds.

Why it happens ? Since I have no tech background, am just taking into consideration my 10th standard science education here

Water vapour definitely exists from the exhast system. Perhaps due to cold temperature, it condenses to tiny droplets & we can actually see the smoke. I have even seen water trickling down from the exhaust. This brings to the question,

How does water vapour forms?
Is it due to the fact that since combustion involves Oxygen & Fuel which necessarily has to contain Hydrogen, there is a reaction which happens during combustion which produces water molecules, perhaps.

This bring to my next question that..
Why is it then that some vehicles/bikes emit this vapour & other doesn't? R15 surely emit that P220 Fi / Non fi both doesn't. What does it shows about the quality of combustion ?

may this is very silly but have been very curious

Water is a by product of the combustion process. CH + O gives CO2 and H2O. When the bike exhaust is cold, it allows for the water to condense and fall out in the form of drops. Once its heated, you dont see it.

When you rev the engine is when you see the white smoke.. thats the water being pushed out by the exhaust gases.

An upward swept exhaust will have lesser amount of water condensing ( due gravity ). If i am not mistaken, i think a small drain hole is given.

Thank you sirji

Hey JD MAN!!!
Howdy bro?? Long time no see ! Wish you a great year ahead
Now the other question remains un answered. What about the quality of combustion ?

i saw this first in Suzuki engines (Omni)

they say this signifies that the engine is finely tuned, and the quality of combustion is best.

water is by product of combustion, but there is already moisture and vapor in air.

antz.bin

the simple chemical equation of combustion of petrol is given by

2C8H18 + 25O2 --> 16CO2 + 18H2O

This clearly means Water(Vapour) is generated in this reaction..
