if its a high pityched knocking or "pinking" sound then the problem could be 3fold one is the grade of petrol is too poor , 2 there is a carbon build up in the engine ( service the car changing plugs etc) or 3 the timing is out if after servicing the car the prob is still there get a garage to put it on a dyno they should be able to diagnose it

If you are experiencing a "rattling" sound this is fuel knock or , more accurately pre - ignition.
It is most commonly causedby the low octane gas we are supplied with.
Don't step on the accelerator so hard. When it knocks, try backing off the accelerator a little and see if it stops while still going up hill.
If so a higher octane or a softer touch may help.
This can damage your engine if it knocks continuously.

A rod would knock a all times, I suspect you may a condition that is called piston slap which occurs when the engine is under a load. This condition is caused by faulty ignition timing and/or need for a higher octane gasoline requirement.

It sounds like you may need to adjust the timing. If its off the car will knock. Also if you have a car that needs premium and you use regular that could be you problem.

just becuz the oil looks fine doesnt mean its still good, you should change it every 3000 miles or three months. also if you have a dirty air filter it can lead to acceleration problems so try changing that.

pinging , otherwise known as death rattle is serious ! if your car is old enough retard the timing a few degrees, if not change your air filter and burn premium gas or use octane boost

Try a higher octane to see if it goes away.
Good luck
