Abstract

The invention relates to an engine exhaust waste heat recovery system. The system comprises an engine, a fan heater, an automobile exhaust catalyst, a thermostat, a three-way joint and a heat exchangepart; an engine water inlet and an engine water outlet are formed in the engine; the heat exchange part is arranged at the periphery of the automobile exhaust catalyst, and the heat exchange part isprovided with a heat exchange part water inlet and a heat exchange part water outlet; the engine water outlet communicates with a thermostat water inlet through a pipeline, and a thermostat water outlet communicates with a heat exchange part water inlet through the pipeline; and the three joints of the three-way joint correspondingly communicate with the other thermostat water outlet, the heat exchange part water outlet and a fan heater water inlet through the pipeline, and a fan heater water outlet communicates with an engine water inlet through the pipeline. The system has the advantages that the water temperature of the engine can be rapidly improved, and the requirement of customers on rapid temperature rise of warm air of an air conditioner can be met; and meanwhile, a heat insulationstructure of the automobile exhaust catalyst is formed through the heat exchange part, so that the cost is reduced, and the lightweight of an automobile is facilitated.

Description

technical field [0001] The invention relates to an automobile engine assembly, in particular to an engine exhaust waste heat recovery system. Background technique [0002] With the popularity of automobile products, automobiles have been widely used in various regions of the world, whether in tropical or frigid regions. The temperature in frigid regions is generally low, even reaching minus 40-50 degrees Celsius. Frequent short-distance driving will make it difficult for the engine to reach the ideal operating temperature. Diluted and emulsified engine oil may occur, affecting the normal operation of the engine lubrication system. In severe cases, the engine may be scrapped due to poor lubrication. The high speed and slow speed make it impossible to quickly meet the customer's demand for air conditioning and heating. [0003] The three-way catalytic converter is the most important external purification device installed in the automobile exhaust system. It can convert some h...
