I see that you have the explanation how they work. I apologize for
the 'rtfm' comment. Thinking back I was in the same position when
someone told me that diesel engines don't have spark plugs...well, not

They don't have spark plugs before they are running either.

He's referring to glow plugs for starting, obviously...
