HOUSING OF ROTARY-PISTON INTERNAL COMBUSTION ENGINE Russian patent published in 2020 - IPC F01C21/06 F02B55/08 

FIELD: engine building.

SUBSTANCE: invention relates to engine building, particularly, to rotary-piston internal combustion engines, and can be used for engine body heat insulation. Engine housing with inlet and outlet channels includes heat-insulating coating applied on inner surface of engine housing and inner surface of outlet channel of engine housing. Coating of the housing is made of inter-ceramic-matrix composite material based on reaction-sintered silicon SiC, zirconium diboride ZrB₂, zirconium disilicide ZrSi₂, ultradispersed carbon C and vanadium V at specified ratio of components in wt% with formation of Nowotny phase with composition Zr₅Si₃C. Coating of inner surface of outlet channel of housing is made of material based on porous silicon carbide SiC, modified with fibers of silicon nitride Si₃N₄ at certain ratio of components in wt%.

EFFECT: invention is aimed at improving heat-shielding, adhesion and strength properties of coating of inner surface of housing of rotary-piston engine and inner surface of outlet channel of housing of rotary-piston engine.
