PROBLEM TO BE SOLVED: To provide an engine EGR device capable of reducing a manufacturing cost of an engine.SOLUTION: In an engine EGR device where an exhaust route 1 is communicated with an intake route 3 through an EGR route 2, the EGR route 2 has an EGR gas lead-out hole 6 extended from an exhaust port 5 of a cylinder head 4 and an EGR gas lead-out pipe 7 connected to the EGR gas lead-out hole 6 with an intake end section 7a thereof inserted into the EGR gas lead-out hole 6. An exhaust end section 7b of the EGR gas lead-out pipe 7 is connected to an intake inlet pipe 11. The EGR gas lead-out pipe 7 is configured to radiate heat of EGR gas 8 into the atmosphere through a peripheral wall thereof to form the EGR route 2 having no water cooling type EGR cooler. |
