DEVICE FOR EXHAUST SYSTEM OF INTERNAL COMBUSTION ENGINE, WHICH OPTIMISES ITS OPERATION Russian patent published in 2012 - IPC F02B27/04 

FIELD: engines and pumps.

SUBSTANCE: device includes housing 1 having inner cavity equipped with inlet 2 and outlet for gas flow, and gas flow swirler 5 located in inner cavity of housing 1. Inner cavity of housing 1 is made in the form of conical part 3 and cylindrical part 4, which are adjacent to each other. Conical part 3 has the shape of flattened cone diverging in the direction of movement from inlet 2 to outlet. Cylindrical part 4 is located after conical part 3 and includes gas flow swirler 5. Swirler 5 is made in the form of cylindrical shell 6 the outer diameter of which is less than inner diameter of cylindrical part 4 of housing 1 cavity. At the bottom 7 of shell 6 there is central cylindrical hole 8, and in its wall 9 there are slots 10 located tangentially to the circle of the above central hole 8. Inside shell 6 and coaxially to it there located is conical nozzle 11 converging in the gas flow movement direction.

EFFECT: creating effective device for exhaust system of internal combustion engine, which is capable of optimising its operation, reducing the fuel consumption and improving operating flexibility.
