i was watching some videos about the hydrolock so the question is why the water stays into the cylinder and didnt go out through the exhaust system ??

thanks

Water doesn't compress like air does. When there's more water than volume at top-dead-center, the engine either breaks or stops (or both) before the exhaust stroke can happen.

My question is, why is there any water in the cylinders in the first place?? :undecided:

A lot of times there is a deep water crossing or a cold air intake to low and a heavy rain. What happens is on the compression stroke when both valves are closed and the water has no place to go and it will not compress then it breaks and bends things.

It gets pulled into the combustion chamber on the intake stroke (piston going down, intake valve open (stroke 1)); it is still in there when the piston comes up (compression stroke (stroke 2)). Water won't compress (not much anyway), something breaks. Normally, the third stroke is when the compressed air/fuel is exploded by the plug, driving the piston down. The forth stroke (exhaust) is when the piston comes up for the 2nd time, this is when the exhaust valve is open.

So, with a 4 stroke engine, we have 2 down and 2 up strokes of the piston. The exhaust is on stroke 4, the broken piston occurs on stroke 2.

Hope that helps.
