The Calculation Algorithm For The Determination Of The Temperature At The End Of The Intake Stroke For Gdi Engines

The paper presents an algorithm for the calculation of the parameters of the working fluid at the end of the intake stroke for a GDI engine. This is only a part of a program developed by the authors, based on an own designed cycle model. The intake process determines the further evolution of the working fluid during the entire engine cycle. The initial parameters depend on the ones at the end of the previous cycle. This algorithm calculates the temperature at the end of the intake stroke and the adiabatic exponent of the intake process.
