This paper uses a one-dimensional (1-D) simulation based approach to compare the steady state and transient performance of a Split Cycle Clean Combustion (SCCC) diesel engine to a similarly sized conventional diesel engine. Caterpillar Inc's one-dimensional modeling tool “Dynasty” is used to convert the simulation model of Caterpillar's current production turbocharged diesel engine Cat® C4.4 (used in their Hydraulic Excavator 316) to operate on the SCCC cycle. Steady state and transient engine performance is compared between the two engine variants. This study is focused only on the performance aspects of engine and relies on the other independently published papers for emissions prediction.
This paper also demonstrates the use of Caterpillar's proprietary modeling software Dynasty to replicate the two cylinder SCCC engine model presented by University of Pisa in their paper . We compare the results from our 1-D model to their Computational Fluid Dynamics (CFD) model to ensure accuracy of results and validate our modeling methodology.
SCCC concept promises significant reduction in gaseous and particulate emissions while maintaining high engine efficiency compared to current state of art diesel engines. No SCCC diesel engine prototypes exist and its complete performance characteristics are unknown. In this study we examine SCCC's overall performance characteristics using a validated 1-D modeling approach.
