Patent number: 11035327Abstract: An engine device including: an EGR device configured to circulate, as EGR gas, a portion of exhaust gas exhausted from an exhaust manifold manifold to an intake manifold; and an EGR cooler configured to cool EGR gas and supply the EGR gas to the EGR device. The EGR cooler includes a heat exchanger and a pair of flange portions. The heat exchanger has a coolant passage and an EGR gas fluid passage alternately stacked. The flange portions are disposed on the heat exchanger. An outlet of the coolant is disposed in one of the flange portions, while an inlet of the coolant is disposed in the other flange portion. An inlet of the EGR gas is disposed in one of the flange portions, while an outlet of the EGR gas is disposed in the other flange portion.Type: GrantFiled: April 14, 2020Date of Patent: June 15, 2021Assignee: YANMAR POWER TECHNOLOGY CO., LTD.Inventors: Masataka Uchibori, Masahiro Akei
