The Merlin 1D engines can restart up to four times, they use the pyrophoric mixture of TEA-TEB (Triethylaluminum-Triethylborane) to ignite the engines. My question is where is this stored in the engine so that it can be released several times to restart the engine?

    $\begingroup$ No accurate diagrams have been published of the Merlin 1D or the engine section of the Falcon. That makes this a difficult question to answer. $\endgroup$ – Hobbes Dec 12 '17 at 10:25
  • $\begingroup$ I would expect the answer to be proprietary and/or ITAR controlled. $\endgroup$ – Carlos N Sep 27 '18 at 13:29
