What is the purpose of installing two or more springs on each valve in an aircraft engine?

  1. To equalize side pressure on the valve stem

  2. To eliminate valve spring vibration or surging

  3. To help equalize valve face loading

  4. To increase the valve's opening speed

The correct answer is: To eliminate valve spring vibration or surging

Installing two or more springs on each valve in an aircraft engine serves to eliminate valve spring vibration or surging. This is important because valve spring vibration or surging can lead to engine failure. The other options are incorrect because A: Equalizing side pressure on the valve stem may not necessarily require the use of multiple springs. C: The purpose of installing multiple springs is not to help equalize valve face loading. D: While installing multiple springs may affect the valve's opening speed, it is not the primary purpose of using two or more springs.
