Investigation of pressure drop in hydro-pneumatic driveline propulsion system for dual hybrid passenger vehicle

The study focused on investigating the pressure drop/loss of the hydro-pneumatic driveline propulsion system. Previous research has shown that there is a very high power loss in the hydro-pneumatic propulsion system. Therefore, this research is carried out to identify the behaviour, cause and strate...
