A diesel engine is one that runs on diesel fuel. It is a compression ignition engine (it does not have spark plugs like a gasoline engine. Also, in a diesel, the fuel is injected into the cylinder under high pressure right when it is needed for burning. A gasoline engine generally mixes the fuel and air under low pressure before entering the cylinder.

A turbo charge is a way of forcing more air into the cylinders.* More air in the cylinders means the engine can produce more power for its size. A turbo charger uses two turbines on the same shaft (or fans if you will). One fan is spun by the hot gases cumming out of the engine as exhaust. This fan provides the power to spin the second fan. The second fan is in the intake system. It develops a pressure to push more air into the cylinders of the engine.

* Note, this describes how a turbo charger is used on 4 cycle engines (diesel or gasoline). Sometimes a turbo charger is used on a 2 cycle engine. In this case its function is similar, but it's purpose is a little different. All current cars and light trucks (in the US and most of the rest of the world) use 4 cycle engines.
