Positive displacement compounding of a heavy duty diesel engine
Technical Report

OSTI ID:5841153
A helical screw type positive displacement (PD) compressor and expander was considered in this study as an alternative to the turbocharger and the power turbine in the Cummins Advanced Turbocompound engine. The Institute of Gas Technology (IGT) completed the design, layout, and performance prediction of the PD machines under a subcontract from Cummins. The results of the study indicate that a screw compressor-expander system is feasible up to at least 750 HP, dry operation of the rotors is feasible, cost and producibility are uncertain, and the system will yield about 4% improvement in brake specific fuel consumption (BSFC) over the Advanced Turbocompound engine.
