  We conduct three-dimensional hydrodynamic simulations of the common envelope
binary interaction and show that if the companion were to launch jets while
interacting with the giant primary star's envelope, the jets would remove a
substantial fraction of the envelope's gas. We use the setup and numerical code
of an earlier common envelope study that did not include jets, with a 0.88Mo,
83Ro red giant star and a 0.3Mo companion. The assumption is that the companion
star accretes mass via an accretion disk that is responsible for launching the
jets which, in the simulations, are injected numerically. For the first time we
conduct simulations that include jets as well as the gravitational energy
released by the inspiraling core-companion system. We find that simulations
with jets unbind approximately three times as much envelope mass than identical
simulations that do not include jets, though the total fraction of unbound gas
remains below 50 per cent for these particular simulations. The jets generate
high velocity outflows in the polar directions. The jets also increase the
final core-companion orbital separation and lead to a kick velocity of the
core-companion binary system. Our results show that, if able to form, jets
could play a crucial role in ejecting the envelope and in shaping the outflow.
