Abstract

An exhaust gas recirculation (EGR) device includes a cylinder head in which an EGR passage that recirculates EGR gas from an exhaust side to an intake side is formed; a coolant chamber formed inside the cylinder head and at a circumference of the EGR passage, through which coolant cooling the EGR gas passing through the EGR passage passes; and a swirl generator disposed at one side of the EGR passage to form swirl at the EGR gas passing through the EGR passage.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority from Korean Patent Application No. 10-2017-0114573 filed in the Korean Intellectual Property Office on September 7, 2017, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to an engine, and more particularly, to an exhaust gas recirculation device that recirculates a part of the exhaust gas from the exhaust side to the intake side to lower the temperature of the combustion chamber, thereby reducing the generation of nitrogen oxides and reducing fuel consumption. Background technique [0004] Generally, an EGR (Exhaust Gas Recirculation) device recirculates part of the exhaust gas (hereinafter referred to as "EGR gas") from the exhaust side of the engine to the intake side, and the EGR gas is mixed with external air to be supplied to the combustion chamber. room. [0005] Specifically, when the exhaust gas i...
