Asymmetric twin-scroll turbocharging technology, as one of the effective
technologies for balancing fuel economy and nitrogen oxide emissions, has been
widely studied in the past decade. In response to the ever-increasing demands
for improved fuel efficiency and reduced exhaust emissions, extensive research
efforts have been dedicated to investigating various aspects of this technology.
Researchers have conducted both experimental and simulation studies to delve
into the intricate flow mechanism of asymmetric twin-scroll turbines.
Furthermore, considerable attention has been given to exploring the optimal
matching between asymmetric twin-scroll turbines and engines, as well as
devising innovative flow control methods for these turbines. Additionally,
researchers have sought to comprehend the impact of exhaust pulse flow on the
performance of asymmetric twin-scroll turbines. Drawing on a comprehensive
review of prior research endeavors, this study presents a meticulous summary of
the advancements made in asymmetric twin-scroll turbocharging technology, with a
specific focus on its application in heavy-duty diesel engines. By analyzing and
synthesizing the findings from these previous investigations, this work also
identifies the existing challenges and outlines the future research priorities
in this field. The continued exploration and optimization of asymmetric
twin-scroll turbocharging technology holds immense promise in enhancing fuel
economy and mitigating nitrogen oxide emissions. Consequently, this research
contributes to the ongoing efforts aimed at achieving sustainable and
environmentally friendly transportation solutions.
