Abstract: An engine EGR system is provided. An EGR passage includes an EGR cooler, an EGR internal passage passing through a cylinder head on an upstream side of the EGR cooler, and a relay passage extending outside the cylinder head and connecting the EGR internal passage to the EGR cooler. The EGR cooler formed in a columnar shape is arranged above an intake manifold so as to locate a gas inflow port on a first end surface side and a gas outflow port on a second end surface side, and the relay passage communicates with the EGR internal passage on an external side of the engine compared to a head EGR gas exit. The EGR cooler inclines downward from the gas outflow port toward the gas inflow port, and the relay passage is connected to the gas inflow port while being bent downward toward the upstream side.

Abstract: An engine EGR system is provided, which includes an engine body, an intake passage, an exhaust passage and an EGR passage configured to recirculate exhaust gas as EGR gas to the intake passage. The EGR passage includes an EGR cooler and an EGR internal passage constituting the EGR passage upstream of the EGR cooler, and including a passage passing through a cylinder head. The EGR internal passage has a bent pipe part including a first bent portion at which an upstream portion of the EGR internal passage is bent away from a gas inflow port of the EGR cooler, a second bent portion located downstream of the first bent portion and bending the EGR internal passage toward the gas inflow port, and an intermediate portion connecting the first and the second bent portions by being disposed therebetween. The water-cooling passage is disposed around the bent pipe part.

Abstract: [Problem to be Solved]
It is to provide an EGR device for an internal combustion engine capable of inhibiting coolant flowing through coolant piping from being affected by heat of an exhaust passage portion to thereby avoid cooling performance of an EGR cooler from deteriorating.
[Solution]
An EGR device 11 for an engine 1 includes: an EGR cooler 13 provided so as to be adjacent to an exhaust cleaning device 9 on a side where an exhaust side wall 1B is located, constituting a part of an EGR passage portion 12, 13, 26, 15; and a coolant introduction pipe 52 and a coolant discharge pipe 53 both to circulate a coolant into an engine body 2 through the EGR cooler 13 to thereby cool a EGR gas flowing through the EGR cooler 13. The coolant introduction pipe 52 and the coolant discharge pipe 53 are installed on an opposite side of the EGR cooler 13 from the exhaust cleaning device 9.
