Simulation Study of the Impact of Two-Stage Turbocharged System on Diesel Engine

Abstract:

With the increasing strictness of emission regulations, development direction of future diesel engines is toward the high thermal efficiency and low emissions. Supercharging technology is an important means for improving output power of diesel engines. This paper deals with the study of the two-stage turbocharging system of the non-road diesel engine. Based on GT-Power software code, a digital model of 6112 diesel engine was established. The supercharged model was calibrated by using the original experimental data. Then, four types of digital models with different two-stage turbocharging systems were constructed. The best two-stage turbocharging system was determined through investigating the impacts of different options on the performance of diesel engines. It was indicated through the study that two-stage turbocharging system can substantially increase the air flowing into the cylinder which increases the potential of power density. At the same time HC and NOx emissions can reduce. Through this study, a theoretical basis and an important reference for adopting the two-stage turbocharging system of the 6112 diesel engine were provided.
