FIELD: machine building.
SUBSTANCE: blowing method of combustion chamber of free-piston two-cylinder power module with common external combustion chamber and linear electric generator, which includes a power module control system, a common external combustion chamber, two piston expansion machines and a linear electric generator. Stator magnet of linear generator consists of two individual parts with remagnetisation coil on one part of stator magnet and coil of generator on its other part. Magnetic poles of two individual parts of stator magnet on some ends are connected to each other, and enclose the bodies of armatures of linear electric generator on opposite ends. For blowing of combustion chamber, power module control transmits electric current of such force and such direction through remagnetisation coil, at which similar magnetic poles are induced on connected ends of individual parts of stator magnet and on their opposite ends enclosing the armatures. As a result, armatures are pushed off each other and pistons of piston groups of power modules connected to armatures at the corresponding position of valves displace the air from compressor cavities of pistons of piston groups through combustion chamber.
EFFECT: improving power module initiation reliability.
