A research staff from the Department of Mechanical Engineering at the University of Technology, namely, Dr. Laith Jaafar Habib, Assis.Dr. Ahmed Abdel Rahman Al-Bayrouti, and Assis.Dr. Muwafaq Ali Tawfiq, published a scientific research on the thermal effects on the piston loading chair Axial diffraction of diesel machine).

The results of the dynamic loading, axial diffraction and axial position, as well as the state of the fixed rotation position, axial diffraction and axial position, showed that by increasing the temperature, the maximum pressure and load capacity would decrease. It was also found that for special conditions of the work of the load chair for the dynamic load and axial diffraction mode, the pressure increases when the temperature or temperature increases. The results show that the axial diffraction will decrease as the temperature or temperature increases. Finally, For axial rotation and for different temperature conditions, the maximum pressure values, axial diffraction and load absorption capacity will increase but the load absorption capacity decreases at a few axial diffraction degrees and then begins to increase at the high degree of axial diffraction.
