Description
Summary:Features of mathematical model construction of gas exchange processes of the four-stroke piston engine and, in particular, statement of initial and boundary conditions are described. The vibrational process of the air column in the intake and exhaust manifolds is considered. The parameters of working processes neglected in the calculation model are specified. The most significant factors for the mass filling of cylinders are determined. The results of calculating the velocity of the working fluid in the exhaust body in the area between the exhaust valve and the first branching are presented.
