Problems solved by technology

[0007] In this case, we have found that impurities are attached to the cooling path of the exhaust gas (the cooling path has a smaller cross-sectional area in order to improve the cooling efficiency of the exhaust gas), and therefore, there is a blockage of the cooling path by the impurities. greater likelihood of

Abstract

The present application discloses an exhaust system for a vehicle and a control method thereof. An exhaust system for a vehicle includes: a first passage including a plurality of first unit flow paths formed by stacking a plurality of heat exchange plates provided with heat exchange fins; a second passage provided in parallel with the first passage, and comprising a plurality of heat exchange tubes respectively forming a plurality of second unit flow paths having a cross-sectional area larger than that of the first unit flow path; opening and closing the unit, arranged to selectively blocking the first passage and the second passage; and a controller configured to control the opening and closing of the unit according to driving conditions of the vehicle so as to control the flow of the exhaust gas to the first passage and the second passage.

Description

technical field [0001] The present disclosure relates to an exhaust system (exhaust system) for a vehicle and a control method thereof in order to effectively cool exhaust gas (exhaust gas). Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] Exhaust gas generated due to combustion of fuel during running of the vehicle includes emission regulated substances that may be harmful to humans or pollute the atmosphere or the like depending on driving conditions of the vehicle. Emission restricted substances include carbon oxides, nitrogen oxides, and the like. [0004] In order to reduce the discharge amount of such emission-restricted substances, vehicles may be provided with various exhaust purification systems. An Exhaust Gas Recirculation (EGR) system corresponds to one of these exhaust gas purification systems, which recirculates a part of the exhaust ...
