“…In the 1960s, researchers realized that the influence of turbochargers on the hysteresis effect of turbocharged ICEs could not be ignored and put forward strategies to improve the turbocharger transient response. For example, reasonably match between the engine and turbocharger, 5,6 adopting variable geometry turbocharger (VGT) or electrically assisted turbocharger, [7][8][9][10] or improving the efficiency of turbine or compressor or reducing the moment of inertia of rotor to improve the transient response performance of turbocharger. 11 The test methods of turbocharger transient response can be divided into the direct method and indirect method.…”

The vital issue of response lag and soot emission during transient operation of turbocharged engine, has been studied so far mainly on experiment in engine system rather than turbocharger basis. The study of turbocharger transient performance, however, is extremely important to manufacturers due to the stringent regulations of exhaust emission and economy for the turbocharger engine. Therefore, a general method independent of the engine for evaluating the transient response performance of a gasoline turbocharger is proposed in this paper. First, an explicit relationship between key thermodynamic parameters of turbine and compressor and the evaluation index of [Formula: see text] that can characterize turbocharger transient response are established. Secondly, the proposed evaluation method is tested and verified using the coupling between GT-Power and MATLAB Simulink software based on the gasoline turbocharger. The simulation results show that the appropriate conditions should be selected for the transient response test, including the starting and ending speed, the starting mass flow rate, etc. For this proposed turbocharger, the value of [Formula: see text] has a good consistency when the ending speed is 200,000 r/min and the initial mass flow rate is in the range of 0.0715∼0.0756 kg/s. Moreover, the influence of rotor moment of inertia, turbine efficiency and compressor efficiency on [Formula: see text] is analyzed in this selected condition. Finally, the evaluating method of the transient response performance of the turbocharger is conducted on a test bench. The test results are in good agreement with the simulation results, indicating that the proposed evaluation method for transient response of turbocharger has a good predictability and can be used for quantitative evaluation of transient response-ability for different turbochargers independent of engine.

“…Pulsating flow of the working medium through the turbocharger turbine and the compressor is typical and is considered in the ICESM; it affects the turbine and partly the compressor operation and results in a different cycle-averaged efficiency at a given mass-flow rate and pressure ratio in comparison with the data from the available maps supplied by the turbocharger manufacturers [32]. Therefore, suitable turbine and compressor efficiency as well as mass-flow correction factors are determined from [4] with the goal to enhance the tuning of the ICESM results with the measurement data.…”

Abstract:The paper outlines a procedure for the computer-controlled calibration of the combined zero-dimensional (0D) and one-dimensional (1D) thermodynamic simulation model of a turbocharged internal combustion engine (ICE). The main purpose of the calibration is to determine input parameters of the simulation model in such a way as to achieve the smallest difference between the results of the measurements and the results of the numerical simulations with minimum consumption of the computing time. An innovative calibration methodology is based on a novel interaction between optimization methods and physically based methods of the selected ICE sub-systems. Therein physically based methods were used for steering the division of the integral ICE to several sub-models and for determining parameters of selected components considering their governing equations. Innovative multistage interaction between optimization methods and physically based methods allows, unlike the use of well-established methods that rely only on the optimization techniques, for successful calibration of a large number of input parameters with low time consumption. Therefore, the proposed method is suitable for efficient calibration of simulation models of advanced ICEs.

A method and results of the analysis of exergy losses that occur in the exhaust system of a turbocharged diesel engine are presented. The aim of the work was to distinguish nodes in the system where exergy losses arise and make precise assessment of losses generated there. Losses were found to be attributable to three main sources: high velocity flow of viscous gas through variable geometry ducts; irreversibility of thermodynamic processes; and heat exchange through the walls of the exhaust system. The adopted model of generating exergy losses has made it possible to carry out a computer simulation for an exemplary turbocharged engine. The results are illustrated in diagrams and discussed.
