FIELD: machine building.
SUBSTANCE: group of inventions relates to a combustion chamber structural unit, a vehicle heating device, as well as to a method of actuating a vehicle heating device equipped with such a structural unit of a combustion chamber. A combustion chamber structural assembly for a vehicle heating device driven by combustible material, comprising: combustion chamber housing (14) with combustion chamber bottom (18) and housing lengthwise longitudinal axis (L) and peripheral wall (16) of combustion chamber surrounding longitudinal axis (L) of housing, wherein combustion chamber bottom (18) and peripheral wall (16) of combustion chamber delimit combustion chamber (20), porous evaporating medium (60) on inner side (which is directed to combustion chamber (20)) of peripheral wall (16) of combustion chamber and / or bottom (18) of combustion chamber, supply pipeline (62) for combustible material for supply of liquid combustible material into porous evaporating medium (60), first combustion zone (50) with first combustion air supply device (68), connected to combustion chamber bottom (18) for primary air supply (VP) of combustion chamber (20) combustion, wherein the porous evaporating medium (60) is located in the first combustion zone (50); following in the direction of longitudinal axis (L) of the first combustion zone (50), the second combustion zone (52) with the second combustion air supply device (70), connected to peripheral wall (16) of combustion chamber for supply of secondary air (VS) for combustion with axial clearance relative to first combustion zone (50) into combustion chamber (20).
EFFECT: invention enables to reduce content of hazardous substances, particularly nitrogen oxide and carbon oxide, in exhaust gas generated during combustion.
