This paper shows the conception and the model of hydraulic single-acting valve drive for internal combustion engines. This drive should give free control for valve lift, valve opening and valve closing time. It consists of parts: electric control valve and hydraulic actuator, whose piston is connected with engine valve and return spring. One of the basic components of high pressure HEUI injector for the Diesel engine - electric valve with solenoid was chosen as electric control valve. Principle of operation, physical and mathematical model of this drive is to be presented in this paper. Presented model consists of electrical, mechanical and hydraulic subsystems: slide of control valve with solenoid coil, power piston of hydraulic actuator with return spring and hydraulic components. Describe the dynamic behaviour of the solenoid was based on non-linear magnetic circuit model. Movement of valve slide and power piston of actuator was based on the motion equation. Description of hydraulic subsystems was based of one-dimensional, compressible flow model. After full system identification basic parameters of this drive (like supply oil pressure or valve lift) will be calculated and analyzed for better load exchange in internal combustion engines.
