FIELD: power-plant engineering.
SUBSTANCE: invention refers to the power-plant engineering. A piston line synchronization technique in a coupled double-cylinder free-piston engine, activating the management system and two single-cycle free-piston engines with the opposed pistons rotation; at that the coupled engine management system traces the single-cycle engines pistons speed values and, provided the pistons speed differs, the management system snaps the gas distribution valve of a single-cycle engine, pistons speed of which exceeds the pistons speed of the other single-cycle engine, into an inverse position. As a result, such a single-cycle engine ceases transforming the combustion product energy into a pistons rotation mechanical energy for a period of time, providing a simultaneous arrival of both single-cycle engine pistons to the points of convergence or points of divergence, whereupon the management system snaps the gas distribution valve into the initial position.
EFFECT: invention ensures the pistons vibration neutralization and their synchronous rotation in phase opposition.
