Talk:Reactivity controlled compression ignition

History
Came here from this video: https://www.youtube.com/watch?v=QailgWUZ1XE

where the (expert) author of a book on WW2 engines expresses his opinion that German high-altitude aero engines of that time were probably the first to use that principle in order to overcome the problem that ordinary sparc ignition and magnetos will not work at very high altitudes as the air looses its insulating properties at low pressure. So a second fuel was injected to facilitate the ignition of the main fuel, also allowing the motors to work with much leaner mixtures. I'm not able to decide if it was actually the same thing, but even if some slight difference exists afaiks that was close enough to be called a precursor many decades earlier and used in actual mass production under difficult conditions. Might improve the article to at least mention it. And it would be sourced by the books of that person in the video as he is well respected in the field of internal combustion engines.
