If only one spring were used on each valve, the valve would surge and bounce because of the natural vibration frequency of the spring.

When valve overlap happens to aircraft reciprocating engine?

High performance piston aircraft engines do have valve overlap, just like high performance engines used in land vehicles, and for the same reasons. Listen to the Continental O-470, IO-520, IO-550, even IO-360 at idle (or Lycoming IO-540) and you can hear the same exhaust note quality as a racing car engine.

What is a valve spring and where is it located on an engine?

The valve springs hold the inlet and exhaust valves shut, so that compression can take place in the cylinder. Most valves are called 'poppet' valves and look like a mushroom. The spring fits around the valve stem and attached at the top by a disc and collets. The valves are opened against the spring tension, by the camshaft lobes, either directly or by push rods. On most engines the valves and springs are on top of the engine, under a tin or aluminum cover. Older 'side valve', 'flat head' engines have the valves at the side of the engine block. Not much can be done to valves, or springs, without first removing the cylinder head. The valve has to be accessed on both sides, in order to release the spring.
