The knocking sound could be caused by a variety of issues, from a loose connecting rod to low oil pressure. It's important to get it checked out by a mechanic as soon as possible to prevent further damage to your engine.

I had a similar issue with my Ford S-Max and it turned out to be a faulty water pump. I would recommend taking it to a trusted mechanic for a diagnostic to determine the exact cause of the knocking sound.

My brother had a similar issue with his Ford Fusion and it was due to a clogged fuel filter. It's a relatively easy and inexpensive fix, so it's worth checking that first before assuming it's a more serious problem.
