What is the liquid that comes out of a car exhaust?
The liquid is water, a byproduct of the combustion process. A simplified chemical formula for this would be: Hydrocarbon fuel + oxygen = carbon dioxide + water. Usually the water goes out the exhaust as a vapour, however it can condense into a liquid if the environment or surface of the exhaust is cold enough.
Is it bad to spray water in your exhaust?
If the exhaust is cold, some water may reach into the muffler but will burn off the next time you run the engine. Now, if you intentionally shoot pressurized water into the exhaust pipe, you could flood the muffler and cause enough of a blockage to cause very rough idling and hot water to spray from the exhaust.
What is the cause for heavy smoke in silencer?

What causes a engine to smoke?
Smoke often leaves car engines as a result of overheating. This can be caused by faulty wire casings, heated residues on the engine block and overheated liquids including oil, transmission fluid and brake fluid. There may also be a fault in your coolant system, or your engine may not have enough lubricant.
What does it mean when your car is blowing white smoke?
White smoke from the exhaust: This could be steam caused by condensation in the exhaust pipe or a more serious issue caused by an engine coolant leak. Excessive amounts of white smoke could indicate head gasket failure.
Why is my car blowing smoke when I start it?
The most common cause of blue exhaust smoke is oil leaking past engine seals and into the cylinders where it then mixes and burns with the fuel. Blue exhaust smoke only at start-up can indicate worn piston seals or damaged or worn valve guides which may also cause a rattling noise.
Is it normal for a car to smoke after sitting?
Smoke coming from a vehicle is a bad sign. It’s normal to see a small puff of white smoke coming from your tailpipe when starting your car after it sits overnight — it’s only water vapor. You may also see steam rising from under the hood on a rainy day as water burns off the radiator or exhaust.
