Turbocharging is playing an increasingly vital role in the development of gasoline engines to reduce fuel consumption and CO2 emissions. Turbocharger design is a key technique used for improving the gasoline engine’s performance. In this study, a new turbocharger design method is proposed by integrating a turbocharger through-flow model with a gasoline engine model for better turbocharger matching. The integrated method was applied to design a new turbocharger according to the performance requirements of a 1.8L turbocharged gasoline engine. Compared to the original prototype, the engine with the new turbocharger designed with the integrated method can achieve a better power and torque curve with about a 4% reduction of fuel consumption at the rated engine speed.
