Please help me ID this diesel engine!

--------------------------------------------------------------------------------
I have acquired a motor from a tech school here that was donated by the factory as a training model.It is new and has training model stamped on it but has not been touched by the Tech school.The block numbers located on the drivers side in the middle are 616-011-28-01.It is a four cylinder diesel. A friend told me it was for the 240D but now he is not sure and I have it running on Ebay right now. Any help you may provide as to what application this is for would be greatly appreciated.Richard.
