| Abstract: | To develop a free-piston engine-alternator power system for hybrid electric vehicles, key design parameters, such as reciprocating mass of the piston assembly, compression ratio, ignition timing, engine specific fuel consumption(SFC) and power output, were optimized based on simulation. The results confirm that rated power of the free-piston engine reaches 7.42 kW and its min. SFC decreases to 313.4 g/(kW·h), improved by 1.17 kW and 34 % respectively than the original. |
