How many cryogenic engines are there till date.

Names are mostly necessary.

  • $\begingroup$ What is your definition of a cryogenic engine? An engine using the cryogenic oxidator LOX only or an engine using cryogenic LOX and a fuel like liquid hydrogen or methane? $\endgroup$ – Uwe Jul 14 '18 at 13:08
  • $\begingroup$ Basically using LOX and any fuel like RP-1, LH2 etc $\endgroup$ – Amar Jul 14 '18 at 13:32

    $\begingroup$ If LOX engines are included, the list is going to be huge. Why do you want to know? There's a list of orbital-launcher engines on Wikipedia, and you can see which ones use LOX or cryo fuels, but it's not complete. en.wikipedia.org/wiki/Comparison_of_orbital_rocket_engines $\endgroup$ – Russell Borogove Jul 14 '18 at 14:01
  • $\begingroup$ I mostly want cryogenic engines list. Actually i'll brought it down to lox/lh2 and lox/RP-1 only. $\endgroup$ – Amar Jul 15 '18 at 11:35
