FIELD: engines and pumps.
SUBSTANCE: set of invention relates to ICE exhaust gas flow heaters. Claimed device comprises the case to make the inner space and the inlet for communication with exhaust gas pipe to feed said gas into the casing, and outlet for communication with exhaust gas discharge pipe. Burner assembly is arranged the casing to combust the fuel in said inner space. Besides, it comprises turbine with inlet for used gases to drive the turbine and outlet communicated with the casing for used gas discharge. Compressor drive by the turbine and provided with ambient air inlet and outlet to feed compressed air into burner. Also, invention discloses the option of engine exhaust gas heater.
EFFECT: isolation of heater from diesel particle filter, decreased length of the latter, separate control over fuel combustion in heater and over engine operation, simplified control and diagnostics.
