摘要： An exhaust gas recirculation (EGR) cooler for mounting to a coolant collector bracket may include a cooler body having a top, a bottom, a length extending in a longitudinal direction, and a width extending in a lateral direction perpendicular to the longitudinal direction, and at least one mount coupled to the bottom of the cooler body. An interior of the mount may be in fluid communication with an interior of the cooler body. A width of the at least one mount in the lateral direction of the cooler body may be equal to or less than the width of the cooler body. The at least one mount may be positioned such that the mount does not extend beyond the width of the cooler body.

摘要： A bed liner system for use in a bed floor of a material hauling machine includes a lower panel that is attachable to the bed floor. The lower panel includes a first plate having a first flange, a first central opening and two first central slots disposed, one each, on either side of the first central opening. The bed liner system further includes an upper panel that is attachable to the lower panel. The upper panel includes a top plate having a second flange having a second central opening and two second central slots disposed that are aligned with corresponding features of the first flange such that a block having a top flange and a bottom flange connected by a web is insertable through the first and second central openings and slidable through one each of the two first and second central slots.

摘要： A coolant collector bracket including a front side, a back side, and a top side is provided. The back side is opposite the front side and includes a plurality of coolant inlets for receiving coolant from a cylinder head. The top side includes an exhaust gas recirculation (EGR) cooler inlet and an EGR coolant outlet. The EGR coolant inlet and the EGR coolant outlet are substantially orthogonal to the plurality of coolant inlets.

摘要： An internal combustion engine system including a cylinder block, a cylinder head attached to the cylinder block, an EGR cooler, and a coolant collector bracket configured to vertically support the EGR cooler is provided. The cylinder head includes a lateral surface including a plurality of fasteners positioned along a bottom edge of the lateral surface. The cylinder head also includes a plurality of coolant passages. The coolant collector bracket is horizontally coupled to the cylinder head and perpendicularly coupled to the EGR cooler. The coolant collector bracket includes a plurality of mounting legs directly coupled to the lateral surface of the cylinder head. The plurality of mounting legs include a plurality of slots. The plurality of mounting legs are slidably inserted onto the plurality of fasteners of the cylinder head via the plurality of slots.
