An EGR cooler includes a tube assembly formed by stacking a plurality of tubes in which exhaust gas flows and a cover plate having a mounting portion formed concavely to mount the tube assembly thereon. A baffle is mounted at the tube assembly and adjusts flow of coolant inflow from a cylinder block. An inlet cover is installed on a first side of an outer surface of the cover plate to supply the exhaust gas to each tube and an outlet cover is installed on a second side of outer surface of the cover plate to exhaust the exhaust gas from each tube. At least one coolant passage in which the coolant flows is formed between the plurality of tubes.

An exhaust system device (1) for a vehicle (100) comprises an exhaust purification device (18) and a first exhaust gas recirculation (EGR) cooler (24). The exhaust purification device (18) is disposed with a central axis of a downstream-side end inclined downwardly toward a rear side of the vehicle (100). The EGR cooler (24) is provided so as to introduce exhaust from a downstream side of the exhaust purification device (18), is adjacent to the exhaust purification device (18) and fixed to the exhaust purification device (18), and is disposed such that a central axis of the EGR cooler (24) is inclined downwardly toward the rear side of the vehicle.

An attaching structure for a motor vehicle includes a cylinder head; an EGR valve arranged adjacent to the cylinder head; a bracket including a first portion attached to the cylinder head, a second portion attached to the EGR valve, and a low rigidity portion arranged between the first portion and the second portion, the low rigidity portion having a rigidity less than remaining portions of the bracket; and a vehicle component arranged adjacent to the EGR valve. The low rigidity portion is formed to break when the EGR valve receives a shock load from the vehicle component.

An exhaust gas cooler comprises at least one exhaust gas pipe for exhaust gas being cooled and is characterized in that at least one gap is provided between the wall of the exhaust gas pipe and laterally adjacent components at the inlet of at least one exhaust gas pipe in the direction of extension of at least one wall perpendicular to the flow direction of the exhaust gas.

An engine (1) of a vehicle powertrain unit (P) includes: an electric exhaust S-VT (27) that is mounted on one end of an exhaust camshaft (26) and changes a rotational phase of the exhaust camshaft; and an EGR device (60) that is provided outside an engine body (10) and connects an intake passage (30) and an exhaust passage (50) together. The EGR device is located closer to a cylinder block (13) than the electric exhaust S-VT in a direction from a cylinder head (14) to the cylinder block, and is arranged so that at least a part of the EGR device and the electric exhaust S-VT overlap with each other when viewed in the direction from the cylinder head to the cylinder block.

Systems are provided for aligning and assembling an exhaust gas recirculation (EGR) assembly with an engine intake housing. In one example, an intake system may include an EGR port housing for coupling the EGR assembly on an intake housing. The EGR port housing may include one or more alignment tabs on at least one side of the EGR port housing for aligning and guiding the EGR assembly during installation onto the intake housing.
