It could be a few things, as you've just bought the vehicle, the first thing to do is give it an oil change, with new oil filter, also clean or replace the air filter, those two things will solve most problems, if its still smokey, change the fuel filter, and put injector cleaner in with your diesel. last resort is to get your injectors nozzles replaced and the fuel pump checked by the professionals

black smoke usually indicates to much fuel being delivered. If this is the case you need to correct it soon or you will damage the catalytic convertor. What year is the vehicle and how many miles on it? Is there a check engine light on? this info would help

!st thing I would suggest is - remove the air metering module, above the air filter, the little black box with the wires going to it, on the inside of this module is a very fine wire, carefully clean it with fuel-system and carburetor cleaner spray, and reinstall the module.
A build up of residue on this wire, will cause an incorrect value for the airflow into the engine, the computer then injects the correct amount of fuel for that amount of air. Less air = less fuel = less power!
