Problems solved by technology

[0002] In the related technology, the exhaust gas discharged from the engine of a traditional vehicle is cooled by the cooler and directly enters the engine for secondary combustion, but the temperature of the exhaust gas after cooling by the cooler may still have a high temperature, making it difficult for the exhaust gas to enter the engine. Meet the requirements of the engine, resulting in insufficient combustion of exhaust gas, reducing the utilization efficiency of exhaust gas

Abstract

The invention discloses an exhaust gas circulation system for a vehicle, a control method and the vehicle, the exhaust gas circulation system for the vehicle comprises an engine, a heat exchanger and a cooler, the heat exchanger is provided with a heat exchanger inlet and a heat exchanger outlet, and the heat exchanger outlet is connected with an air inlet of the engine; the cooler is provided with a cooler inlet and a cooler outlet, the cooler inlet is connected with an exhaust port of the engine, and the cooler outlet is connected with the air inlet of the engine and the inlet of the heat exchanger. According to the exhaust gas circulation system, the cooler is arranged in the waste gas circulation system, the outlet of the cooler is connected with the inlet of the heat exchanger and the gas inlet of the engine, part of waste gas at the outlet of the cooler can enter the heat exchanger to be cooled twice, and the actual temperature of the waste gas entering the engine is effectively reduced; the waste gas can be fully combusted in the engine, and the lean combustion of the engine is better achieved.

Description

technical field [0001] The invention relates to the field of vehicle exhaust gas treatment, in particular to an exhaust gas circulation system for a vehicle, a control method and the vehicle. Background technique [0002] In the related technology, the exhaust gas discharged from the engine of a traditional vehicle is cooled by the cooler and directly enters the engine for secondary combustion, but the temperature of the exhaust gas after cooling by the cooler may still have a high temperature, making it difficult for the exhaust gas to enter the engine. Meet the requirements of the engine, resulting in insufficient combustion of exhaust gas, reducing the utilization efficiency of exhaust gas. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, it is an object of the invention to propose an exhaust gas recirculation system for a vehicle. The exhaust gas circulation system is...
