Sažetak
A detailed experimental research is time consuming and expensive, which increases the use of numerical simulations in all engine development stages, especially for extensive analysis and optimization of various operating parameters that affect the engine operation. In such cases the so- called cycle-simulation models, based on 1-D/0-D approach, can be very helpful by shortening the process of engine’s operating map calibration. In recent years, such models are more and more intended to be real-time capable to enable their application in HiL (Hardware-in-the-Loop) simulations. Therefore, the challenge is to find the optimal balance between predictability and calculation speed of the model. This chapter presents a calibration procedure of a real-time cycle-simulation model with the aim of achieving good predictability of the model with minimal requirements for experimental investigations necessary for calibration of model parameters. The procedure includes calibration of both gas exchange and combustion model constants with the help of Proportional Integral (PI) controllers for each of the experimentally investigated operating points, and afterwards the parametrization of the selected constants based on the calibration results. The resulting parametrized model features computational speed compatible for HiL simulations, and the validation of the model showed that calculation results are in close agreement with the experimentally obtained results in the entire operating map of a naturally aspirated 1.4 L spark ignited engine.
