| Abstract: | A hydraulic free piston engine (HFPE) integrates one hydraulic pump and diesel engine into one compact assembly. As a compound engine used for nonstiff transmission of power, its internal energy conversion and external energy recuperation process were analyzed. The great advantages such as high fuel economy, low energy conversion loss, flexible power combination, multi substitute fuel and energy recapture were described. Last but not the least, HFPE makes multi load control easy through serving as power central station and using hydraulic transformer as interface between hydraulic motors and common pressure rail. HFPE has a promising potential in mobile machinery that starts and stops frequently. |
