Abstract

The invention provides an automobile waste heat recovering and reusing system applied to the technical field of automobile engines. An exhaust pipe (3) of the automobile waste heat recovering and reusing system comprises an exhaust pipe branch pipeline I (4) and an exhaust pipe branch pipeline II (5). A heat exchanger (6) is arranged on the exhaust pipe branch pipeline II (5). A bypass valve actuator (7) and a bypass valve (8) are arranged on the exhaust pipe (3). A spiral heat-exchange pipe part (10) is arranged on the portion, located in the heat exchanger (6), of a cooling liquid pipeline (9). A heat exchanger outlet cooling liquid temperature sensor (11) is arranged on the portion, stretching out of the heat exchanger (6), of the cooling liquid pipeline (9). According to the automobilewaste heat recovering and reusing system, the structure is simple; during cold starting of an automobile, part of heat in automobile exhaust can be recovered to be used for heating cooling liquid inan automobile engine cooling system, so that an engine is heated rapidly and reliably, the heat efficiency during cold starting of the engine is improved, and combustion in a cylinder is made more sufficient.

Description

technical field [0001] The invention belongs to the technical field of automobile engines, and more specifically relates to an automobile waste heat recovery and reuse system. Background technique [0002] With the global energy situation becoming more and more tense, environmental protection becoming more and more urgent, and the number of cars in various countries in the world continues to rise, traditional fuel vehicles and hybrid vehicles are facing huge pressure on energy conservation and emission reduction. For traditional automobile engines, the water temperature in the engine water jacket is low during cold start. At this time, the lubrication effect of the various parts of the engine is poor, the friction force is large, and the thermal efficiency is low. At this time, the combustion in the cylinder is relatively insufficient, so The production and emission of harmful gases are relatively high. At present, there is no good way to improve the thermal efficiency of th...
