Question

Which of the following are advantages of dual ignition in aircraft engines?

1. Gives a more complete and quick combustion of the fuel.
2. Provides a backup magneto system.
3. Increases the output power of the engine.
4. Permits the use of lower grade fuels.
5. Increases the intensity of the spark at the spark plugs.

Answer 1

Dual ignition in aircraft engines enhances combustion efficiency and provides a backup magneto system, thus improving reliability and safety during flight operations. Option 1 &2 arethe correct answers.

Step-by-step explanation:

The concept of dual ignition in aircraft engines carries several advantages that are critical to the performance and safety of aviation technology. One of the primary beneficial attributes of dual ignition is that it gives a more complete and quicker combustion of the fuel which can contribute to greater engine efficiency and smooth operation.

Another key advantage is the provision of a backup magneto system, which greatly enhances the reliability of the engine by ensuring that if one ignition system fails, the other can continue to function and allow for a safe flight.

While the increased intensity of the spark at the spark plugs is not directly a result of dual ignition, the system does ensure more reliable ignition by providing two separate sparks. This can lead to a finer combustion process, but does not necessarily increase the power output of the engine. Additionally, dual ignition systems do not permit the use of lower grade fuels; the quality of fuel required is determined by the engine design and the combustion chamber characteristics.

In summary, the correct options that describe the advantages of dual ignition in aircraft engines are:

1. Gives a more complete and quick combustion of the fuel.
2. Provides a backup magneto system.
