Structural Principle and Performance of Three Cylinder Hydraulic Confined Piston Engine
Three cylinder HCPE integrates the advantages of HFPE and engine driving plunger pump system, whose structure is compact, energy transforming and transmitting route is short. The structural principle of three cylinder HCPE was described. The dynamical simulation model of HCPE was constructed. Through simulation, volumetric efficiency ranges between 27% and 97%, is slightly influenced by output pressure and more practical rotational speed should be 1 600～1 800 r/min; the universal characteristic of fuel consumption rate ranges between 228.23 g/(kW • h) and 984.11 g/(kW • h), output pressure between 1.01 MPa and 4.27 MPa, output flow between 3.80 m3/h and 16.91 m3/h, effective thermal efficiency between 12.06% and 37.67%, and effective power between 1.12 kW and 19.93 kW, which are evidently better than engine driving lunger system, but slightly worse than HFPE.
