TWO-STROKE DETONATION ENGINE Russian patent published in 2013 - IPC F02B75/26 F02B75/04 

FIELD: engines and pumps.

SUBSTANCE: two-stroke detonation engine comprises a vessel (1), at least two cylinders (10), a bent shaft (3), a hinged joint of unequal angular speeds, an inclined shaft (6), pistons (11), installed in cylinders (10), and hingedly joined to connecting rod heads (12). Other heads of connecting rods (12) are hingedly connected to a crosspiece (8) of the hinged joint of unequal angular speeds. The elbow of the bent shaft (3) is made in the form of a slant sleeve (4), installed on it with the help of a movable splint joint. The slant sleeve (4) and the connected inclined shaft (6) have working surfaces at both sides from the axis of rocking of the crosspiece (8) of the hinged joint of unequal angular speeds. The connection of the inclined shaft (6) with the slant sleeve (4) and the crosspiece (8) of the hinged joint of unequal angular speeds is realised by means of self-centring inserts. Oppositely and in the counterphase to the available pistons, connecting rods, the crosspiece of the hinged joint of unequal angular speeds, the inclined shaft, slant sleeve. there are the same connected in the same manner pistons (13), connecting rods (14), a crosspiece (15) of the hinged joint of unequal angular speeds, an inclined shaft (16) and a slant sleeve (17). The engine comprises a mechanism to limit pressure in combustion chambers and a device to control extent of compression. A supercharge is represented by underside piston cavities, in which windows are arranged. On the bent shaft (3) there is a slot and a circular bore. Inlet windows are made in two rows in each cylinder and accordingly are separately connected with underside piston cavities of this cylinder by means of tracts. Inlet windows connected to the tract, where fuel is supplied, are arranged as the last from the top dead centre and are inclined. The engine has forward-slot blowing.

EFFECT: increased engine resource due to reduced speed and pressure in friction vapours.
