In boom up mode, only the engine drove the hydraulic pump, with the speed and torque of the engine illustrated in Fig. 5 (b) and (c), respectively. As there is no electric motor/generator to provide additional energy, the working points of the engine differ from those of EHCVP and are depicted in Fig. 6. During boom down mode, the ...

As there is no electric motor/generator to provide additional energy, the working points of the engine differ from those of EHCVP and are depicted in Fig. 6. During boom down mode, the cylinder moved down without any energy regeneration. Fig. 6 illustrates the working points of the engine for EHCVP II, EHCVP, and ...
