COMBUSTION CHAMBER ASSEMBLY FOR FUEL-FIRED VEHICLE HEATER Russian patent published in 2021 - IPC B60H1/22 

FIELD: vehicle heaters.

SUBSTANCE: invention relates to vehicle heaters. The combustion chamber assembly contains a mixing chamber (20) extending in the direction of the longitudinal axis (L) of the combustion chamber assembly for forming a fuel-air mixture, a fuel supply device (38) for supplying fuel (B) to the mixing chamber (20), an air supply device (V) for combustion into the mixing chamber (20), a diffuser (22) located in the direction of the longitudinal axis (L) of the combustion chamber assembly downstream of the mixing chamber (20). The fuel supply device (38) contains an evaporating device (36), and the device (18) for supplying combustion air - a device (14) for creating a vortex flow. The vortex flow generating device (14) is located in the direction of the longitudinal axis (L) of the combustion chamber assembly upstream in front of the mixing chamber (20) with the evaporation device (36).

EFFECT: reduced emission of nitrogen oxide in combustion mode.
