I park my car in my garage and I was wondering sometimes why does water come out of my exhaust pipe when i start my car...?

 

when you washed the car you might have sprayed water up the tail pipe

 

It happens on all cars. I dont drive my car in winter or right now for the matter of fact and condensation buildes up in your engine. You get water in your tubes etc. So when you start your car it blows all that condensation out. This will happen if:

a. you dont drive the car very much
b. your on lots of short trips
c. you spry water up your tail pipe

You wonder why exhaust sytems that arent stainless stell dont last very long its casue of all the condensation.

hope that helps. If you have clamps then it will actually drip out of the gaps when you shut your car off etc. but if its all welded you will only notice it when its running.


I kanda like it seeing water droplerts behind your car after you rev it up on dry concrete hehe


HAVE FUN

 

water accelerates corrosion.

water is a byproduct of combustion.! period!
thats why water comes out of your exhaust, NOT
because u sprayed water in it.!!!

Your Cat does convert things to H20.

 

yup not cause you srpayed water in but it could be j/k

 

Don't have a CAT converter...

 

WRONG>!!!

did u READ my post...

water is a byproduct of combustion..!!!! if forms b4 the cat!! and passes through
the exhaust system...the reason exhausts rust inside out, (from short trips)
is because the entire exhaust system does not heat up to temperatures
hot enough to evaporate the water thats building up inside the exhaust system.!

Maybe, but I know for a fact that the Cat Converter converts some of those harmful gases into less harmful ones and H20. But Cats are very hot so most of it would evaporate. Plus if water was coming from before the cat it would be one hell of a trick to get it to flow all the way through the several honeycombs and then out the other side in any amount that would even be noticable without being vaporized from the heat.

 

once again ..

water is a byproduct of COMBUSTION...!!
what isnt clear here...??...yes it is formed B4 the CAT..
actually in the combustion chanber itself
once again...water is a byproduct of combustion..
it accumulates throughout the exhaust system
and the excessice heat helps evaoprate any accumulated
water vapour.!

take a chemistry course youll undestand..

 

yup thats right

 

What? you mean it's not normal when my exhaust is spraying out water like a garden hose everyday?
