FIELD: engines.
SUBSTANCE: invention relates to exhaust gas heat exchangers for internal combustion engines. Disclosed is an exhaust gas heat exchanger 11 for connection to flow of exhaust gases from a vehicle engine 5 having a plurality of channels 30 for redirecting exhaust gases and several coolant channels 32 for transferring heat from exhaust gases passing through exhaust gas heat exchanger 11 to coolant, which is used to supply heat to a vehicle cab. Exhaust gas heat exchanger 11 comprises an outlet 55, which enables to use cooled exhaust gases in a low-pressure exhaust gas recycling system 50. Exhaust gas heat exchanger 11 thus performs two functions - recovering heat energy for use in heater 2 of cab and cooling exhaust gases for use in low-pressure exhaust gas recycling system 50.
EFFECT: invention enables recovery of residual heat of exhaust gases for heating a vehicle cab, allowing use of cooled exhaust gases in a low-pressure exhaust gas recycling system 50.
