The efficiency of mobile hydraulic system with diesel engine and axial piston pump analysis

الملخص EN

Hydraulic systems are used in a wide variety of applications, stationary as well as mobile.

hydraulic pumps and motors are used in many cases for both propulsion and various work functions and are thus often a significant user of energy.

efficiency performance of mobile hydraulic systems over a wide range of pressure and speed conditions is crucially important for power unit to save energy.

in this study, the efficiency of a mobile hydraulic system is studied.

mobile hydraulic systems are equipped with diesel engine as power unit and axial piston pumps used for hydraulic power.

the relationships between the efficiency of the axial piston pump and the power loss and the efficiency of diesel engine and the output power were explained by graphics.

the average power loss of axial piston pump has changed from 0.1 kW to 2.5 kW.

losses of an axial piston pump have been determined; thus, fuel consumption and CO2 emission caused by these losses were shown by graph.

the CO2 emission was affected by the increase in pressure and speed; it reached from 5.231 kg/h to 5.61 kg/h.

the research focused on analysis for axial piston pump in mobile applications, with emphasis on pump losses, fuel consumption, and CO2 emission.
