Hello everybody! I'm doing a report on a B13 engine for school. And i'm stuck. Maybe someone can help me? It's about the sparkplugs. The trailing one has a hole of 4 mm were the leading one has a hole of 13 mm. Anyone who can tell me exactly why this is? I know it has something to do with the rotorpoint passing it. Excuse me for my bad english, it's not my mothertongue. Thanks in advance!

Come on! need some help pls. the report is due to tomorrow.

 

1. The correct name is '13B' , not B13. You will find much more information on the web if you search for 13B.


2. Here is a good explanation of how the rotary engine works: http://science.howstuffworks.com/rotary-engine.htm


3. Your report is YOUR problem, not ours. When was the report assigned to you?


4. Here is a hint: the trailng spark plug is at a different stage of the combustion process than the leading spark plug. What does this mean in terms of pressure, temperature, and wear?
