An integrated simulation platform for turbocharged internal combustion engines has been developed. Multi-dimensional computational fluid dynamic (CFD) codes are integrated into the system to model the turbocharging circuit, gas circuit, in-cylinder circuit, coolant and oil circuits. As the turbocharger is a critical factor for the IC engine, a turbocharger through-flow model based on mass, momentum, and energy conservation equations has been developed and added in the integrated platform. Compared with the traditional MAP method, the through-flow model can solve the problems of transient matching and lack of numerous experimental maps during the pre-prototype engine design. Partial systems in the integrated platform, such as the in-cylinder flow and combustion circuit, can be modeled by 3-D CFD codes for the investigation of the detailed flow patterns. The data exchange between different software modules is steered by a vehicle simulation code which is also used to determine the operating and load conditions of the engine. The platform was validated using experimental data and the analysis of a turbocharged diesel engine's thermal performance was conducted. The total fuel energy distribution was listed to observe the energy conversion, control and utilization at the engine system level.
