AI Technical Summary
Current BEV technology lacks energy density comparable to traditional fuels, limiting its range and practicality for heavy-duty applications, and hydrogen fuel delivery systems face challenges in maintaining consistent pressure for internal combustion engines, leading to inefficiencies and parasitic losses.
A compressor system with a hydraulic drive pump and buffer tank maintains consistent gas pressure for hydrogen fuel delivery by controlling the hydraulic drive pump and spool valve, ensuring efficient operation and separation from the engine, using a closed-loop hydraulic circuit and heat exchanger to regulate temperature and pressure.
The system ensures reliable and efficient delivery of hydrogen gas at consistent pressures, reducing parasitic losses and enhancing engine performance, while allowing for compact packaging and safety by separating the compressor from the engine bay.
