Abstract

An exhaust gas heat exchange system of an automobile engine is used for realizing reutilization of exhaust gas energy of the engine and achieving the purposes of energy conservation, emission reduction and improvement on vehicle comfort. The system comprises an automobile warm air blower circulation pipeline, an engine gas exhaust pipeline and an engine gas inlet pipeline, wherein the automobile warm air blower circulation pipeline is filled with a circulation water medium and connected with a water inlet and a water outlet of an automobile warm air blower. The system is characterized in that a first heat exchange water sleeve which is in parallel connection with the engine gas exhaust pipeline and a second heat exchange water sleeve which is in parallel connection with the engine gas inlet pipeline are arranged on the automobile warm air blower circulation pipeline. According to the system, exhaust energy of the engine is fully used, so that the heat efficiency of the engine is improved, the economy and the emission performance of the engine are improved, and the requirement for the vehicle driving comfort is met.

Description

technical field [0001] The invention relates to a heat exchange system, in particular to an automobile engine exhaust gas heat exchange system, which belongs to the technical field of internal combustion engines.
