Abstract
ABSTRACT
The paper deals with the mathematical model of the in common unsteady and steady working conditions of hydraulic converter and internal combustion engine . For the unsteady and steady in common working conditions , the recommended system of differential equations is possible to solve using numerical methods and permits to find the unknown variables which are displacement speed , angular speed of hydraulic pump and ratio of change , depending on known parameters and time . Paper contains some graphic results which were obtained for a numerical case and the computer programme .
