Hello and welcome to JustAnswer!

There are several things that could be making a knocking noise. it may be a rod or main bearing, piston or wristpin issue, if it's a lighter ticking type noise then it could be valvetrain related, the problem could actually be related to an engine accessory or the flywheel or clutch if it's a manual transmission.

Can you tell what area it comes from? Is it better described as a knock or a tick?
