Simulation on Performance of Sequential Turbocharging Diesel Engine with Inlet and Exhaust Bypass System

Abstract

Sequential turbocharging and inlet/exhaust bypass (STC-CAB) were composited to used on diesel engine, which can expand engine running area in part load and optimize the matching of turbocharger and diesel engine. The simulation was studied based on GT-POWER software in order to investigate the engine performance difference caused by stc-cab system. The simulation results showed that STC-CAB system can make the compressor away from surge area and expand diesel engine running area, improve the performance of torque in low load.
