Multi-orifice nozzle air evacuator assembly for a ventilation system of a diesel engine

A crankcase ventilation system interfaced between a crankcase port and an exhaust port of a diesel engine, comprising:

• a housing connected between the crankcase and exhaust ports of the diesel engine;
• a source of compressed air;
• and
• a crankcase air evacuator assembly comprising:
• a multi-orifice nozzle comprising a plurality of nozzle orifices located within said housing, said multi-orifice nozzle being connected to said source of compressed air, wherein air from said source pressurably effuses as nozzle air from said plurality of nozzle orifices;
• and
• an evacuator tube located in said housing, said evacuator tube comprising a tube body having a central passage, said central passage having an inlet and an opposite outlet interconnected with said exhaust port;
• said plurality of nozzle orifices being located proximal to, and in alignment with, said inlet of said central passage;
• wherein said nozzle air passes into said inlet thereby creating a low pressure region therearound which sucks ambient air of said housing into said inlet and thereby evacutes said crankcase air from said crankcase port and expels the crankcase air to said exhaust port.
