This question already has an answer here:
Are spark plugs used in kero-LOx engine(say J1 engines)? If so, then there are two major issues when using spark plug to ignite kerosene.
- Wetting of the spark plug causes spark to be smaller and the energy might be less. Sparks tend to be larger when used in gas media. Wetting of the electrode reduces spark size.
- Due to the above, the temperature achieved might be less and hence kerosene might not be vaporised completely before reaching flash point.
How are these issues overcome?
