Chemical rockets are generally used on manned spacecraft. Ion propulsion has been used on a few unmanned spacecraft.
it stands for Twin Ion Engine, which was the standard means for small spacecraft propulsion during the Imperial Era.

It use propulsion system. Propulsion, like Jet engine but the rocket or space craft would store oxygen to combusted with fuel. Some advance spacecraft would use ion thruster by electrically heated up a gas to extremely high temperature and resulted to very fast stream of gas ejected on the back side of the spacecraft.
Rockets. Usually chemical rockets, but some tests are underway with ion propulsion. (That's also a rocket, but it uses electrical forces to accelerate the exhaust mass instead of chemical reactions.)
Main propulsion is the function of the marine main engine.
Main engine is used for propulsion of ship.
The main source of propulsion.
A propeller is completely external and is the main source of propulsion for a airplane with a piston or turbojet engine. A turbofan is more enclosed and provides some propulsion along with also cooling the jet engine that is the main source of propulsion.

Maine engine(s) using for propulsion purpose.
A very powerful internal combustion engine.
