Just got this problem with my car, it could be the tappets, when your car idles does this noise dissapear sometime then come back ?, if so one of the tappets is sticking, a good oil flush and additive should cure it.

loud knocking and thumping noises will NOT be cured with oil additive

is it idling right? milage? is it actually the engine or something in the engine? what engine is it?

thumping noises is usually bottom end, bearings, crank, conrods etc...
