The disclosure illustrates an exhaust gas turbine and compressor system for use with a pneumatic conveyor where the exhaust gas is supplied by an internal combustion engine. The engine utilizes a variable geometry turbine device for changing the torque characteristics of the turbine so as to vary the mass flow of air from the compressor driven by the turbine. As a result, the compressor output will be sufficient to supply air to the engine or to the pneumatic conveyor system while the engine is naturally aspirated. A diverter valve is provided for selectively directing air from the outlet of the compressor either to the air intake of the engine or the pneumatic conveyor.

A system for selectively supplying compressed air to the intake of an internal combustion engine and to a pneumatic conveying system, said system comprising: a rotatable turbine and a turbine housing having inlet means receiving exhaust gases from said internal combustion engine, and nozzle means for directing exhaust gases across said turbine for rotation thereof, a compressor connected to and driven by said turbine for pressurizing air, means operatively connected in the inlet duct of the turbine for selectively changing the nozzle area between a first relatively large area from which sufficient compressed air can be supplied by the compressor means to operate the engine at full load and a second relatively small area from which sufficient compressed air can be supplied by the compressor means to operate a pneumatic conveying system while the engine operates at high RPM under a no-load condition, and valve means for selectively directing air from the compressor to the air intake of said engine in one position and in another position directing air from the compressor to the pneumatic conveying system and simultaneously naturally aspirating the engine.
