  We conducted three-dimensional hydrodynamical simulations of common envelope
evolution (CEE) of a neutron star (NS) or a black hole (BH) inside a red
supergiant (RSG) envelope and find that the jets that we expect the NS/BH to
launch during the CEE spin-up the common envelope. We find that when the NS/BH
launches jets that are exactly perpendicular to the orbital plane (the jets are
aligned with the orbital angular momentum) the jets deposit angular momentum to
the envelope that is aligned with the orbital angular momentum. When the jets'
axis is inclined to the orbital angular momentum axis so is the angular
momentum that the jets deposit to the envelope. Such tilted jets might be
launched when the NS/BH has a close companion when it enters the RSG envelope.
We did not allow for spiralling-in and could follow the evolution for only
three orbits. The first orbit mimics the plunge-in phase of the CEE, when the
NS/BH rapidly dives in, while the third orbit mimics the self-regulated phase
when spiralling-in is very slow. We find that the jets deposit significant
amount of angular momentum only during the plunge-in phase. A post-CEE core
collapse supernova explosion will leave two NS/BH, bound or unbound, whose spin
might be misaligned to the orbital angular momentum. Our results strengthen an
earlier claim that inclined-triple-star CEE might lead to spin-orbit
misalignment of NS/BH-NS/BH binary systems.
