Latest Patents

Qiang Liu holds a patent for a "Method and system for controlling engine speed and boom-type engineering machine." This patent, which is particularly relevant to boom-type engineering machinery, outlines a method for controlling the output speed of an engine during boom actions. The process involves detecting the load pressure of a hydraulic system and the moving speed of the boom. A central control unit determines the target speed of the engine based on these parameters and communicates this to the engine control unit. The engine control unit then performs a speed closed-loop adjustment to ensure that the current engine speed aligns with the target speed. This innovation not only improves operational efficiency but also enhances the overall functionality of boom-type engineering machines.
