CONSTRUCTION CHAMBER ASSEMBLY FOR VEHICLE HEATING DEVICE DRIVEN BY VEHICLE COMBUSTIBLE MATERIAL Russian patent published in 2018 - IPC F23R3/40 F23R3/26 

FIELD: fuel combustion devices.

SUBSTANCE: combustion chamber assembly for the vehicle heating device driven by the combustible material includes combustion chamber housing (12) with combustion chamber (18) next to longitudinal axis (L) of body behind peripheral wall (14), which is bounded by peripheral wall (14) and bottom zone (16) and space (32) for the exhaust gas flow open in the direction of longitudinal axis (L) of the body, flame tube (30) and flap (34) from the flame with through hole (60). Between flame tube (30) and surrounding body (38), space (46) is formed for the backflow of the exhaust gases. In first axial end region (48) of space (46) for the return flow of the exhaust gases, space (32) for the exhaust gas flow is open in the direction of space (46) for the backflow of the exhaust gases. In space (46) for the return flow of the exhaust gases, catalyst system (54) adapted to pass through it exhaust gases passing through exhaust gas return space (46) is provided.

EFFECT: invention is aimed at reducing emissions of harmful substances.
