DEVICE AND SYSTEM FOR DISTRIBUTION OF ADDITIVE INTO EXHAUST Russian patent published in 2020 - IPC F01N13/18 F01N13/08 F01N3/20 

FIELD: engine building.

SUBSTANCE: present invention relates to device for distribution of additive to exhaust, intended for exhaust system of internal combustion engine (2). Device for distribution of additive to exhaust comprises outlet tubular element (14), device (20) for injection of additive into exhaust and main evaporating element (16), at that, the main evaporating element (16) is a tubular element located in the inner space of the outlet tubular element (14), has a predetermined gap between the inner surface of the outlet tubular element (14) and the outer surface of the main evaporating element (16) and protrudes from outlet tubular element (14) at outlet end, and device (20) for injection of additive into exhaust is configured to inject liquid additive into exhaust from point on inner surface of outlet tubular member (14) towards inner surface of main evaporation element (16), and the device for distributing the additive to the exhaust is characterized in that device (20) for injecting an additive into the exhaust is a device for injecting liquid only, and in that the main evaporating element (16) has a length which is sufficiently low, to allow injection of injected liquid additive into exhaust from main evaporator (16) outlet end. Present invention also relates to a system for distributing an additive to an exhaust and to vehicle (1) comprising a device for distributing an additive to the exhaust.

EFFECT: proposed device for distribution of additive into exhaust.
