Abstract

A two-stage linkage type automobile tail gas thermoelectric power generation system comprises an engine (1), an engine cooling water circulating controller (3), a turbocharger (2) and a turbine bypass gas circuit (5), wherein a turbine motor outlet in the turbocharger (2) is connected with a gas exhausting pipe (7) through a connecting pipeline II (27); the connecting pipeline II (27) is provided with a thermoelectric power generation device I (6); the turbine bypass gas circuit (5) is provided with a pressure release valve (4); the turbine bypass gas circuit (5) is provided with a thermoelectric power generation device II (10); a gas inlet and a gas outlet of the thermoelectric power generation device II (10) are respectively connected with the turbine bypass gas circuit (5); and a cooling liquid inlet and a cooling liquid outlet of the thermoelectric power generation device II (10) are respectively connected with a water feeding pipeline and a water draining pipeline of the engine cooling water circulating controller (3). The two-stage linkage type automobile tail gas thermoelectric power generation system has a two-stage linkage function; and the total generation power is obviously increased.

Description

technical field [0001] The invention relates to a power generation system of temperature difference of automobile exhaust, more specifically relates to a two-stage linkage type power generation system of temperature difference of vehicle tail gas. Background technique [0002] When an internal combustion engine vehicle is working, the energy generated by fuel combustion cannot be completely converted into kinetic energy. According to relevant statistics, if the total energy consumption of a vehicle’s fuel consumption is set to 100%, only about 30% is used to actually drive the vehicle; the remaining about 70% Energy is wasted in various forms. If this part of waste heat is recovered for power generation, the fuel utilization efficiency of the internal combustion engine will be greatly improved, the fuel consumption of the vehicle will be effectively reduced, the pollution to the environment will be reduced, and good social benefits and considerable economic benefits will be b...
