Fully-controlled, free-piston engine |
摘要 |
A free-piston engine includes at least one dual piston assembly, each of which has a pair of axially opposed combustion cylinders and free-floating combustion pistons respectively mounted in the combustion cylinders for reciprocating linear motion responsive to successive combustions. A pumping piston extends from and is fixed to each of the combustion pistons and reciprocates within a hydraulic cylinder located between paired combustion cylinders. The paired combustion cylinders are rigidly connected by a cage for reciprocating movement in tandem. |
