FIELD: engine devices and pumps.
SUBSTANCE: engine has two pairs of blades on two hollow shafts, dividing the chamber into four variable-volume working chambers, gas exchange channels and windows, a blade coupling mechanism made by fixed connection of carriers of two planet crank-and-rod mechanisms mounted from the chamber ends, a prechamber rendered out of chamber limits, a nozzle installed in the prechamber, a channel connecting the prechamber with the working chamber and divided by a partition into the inlet and outlet section. The engine has a glow plug with a filament element. The prechamber is made heat-insulated in the form of an arc enveloping the partition. The locking element of air valve is made the farthest from the blade rotation axis of the blade working surface with the possibility of overlapping the gas exchange windows. The distance between gas exchange windows of prechamber is designed to overlap these windows.
EFFECT: increasing resource, fuel combustion efficiency, simplifying the creation of compression, reducing the thermal strength of blade and ensuring the operation of engine on fuel with low detonation resistance.
