DETAILED DESCRIPTION
(15) Both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the features, as claimed. As used herein, the terms “comprises,” “comprising,” “having,” including,” or other variations thereof, are intended to cover a non-exclusive inclusion such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements, but may include other elements not expressly listed or inherent to such a process, method, article, or apparatus. Moreover, in this disclosure, relative terms, such as, for example, “about,” “substantially,” “generally,” and “approximately” are used to indicate a possible variation of ±10% in the stated value.

(18) The EGR cooler 16 forms a portion of the EGR flow path and includes a generally cylindrical-shaped heat exchanger having an EGR inlet end 17 and outlet end 19. EGR cooler 16 may be of any appropriate type, such as a parallel tube or parallel flow heat exchanger having a coolant inlet at one end, and a coolant exit at an opposite end. In some embodiments, EGR cooler 16 may have a rectangular, oval, and/or asymmetrical shape. As will be explained in more detail below, EGR cooler 16 may include a plurality of mounting posts 30 for connecting the EGR cooler 16 to a top portion of the coolant collector bracket 18. The EGR cooler 16 may include four mounting posts 30, only two of which can be seen in

(21) EGR coolant outlet 36 may be located along the longitudinal axis of front mount 87, and generally centrally positioned between the fastener connectors 50 of front mount 87. EGR coolant inlet 38 of coolant collector bracket 18 may similarly be located along the longitudinal axis of rear mount 89, and generally centrally positioned between the fastener connectors 50 of the rear mount 89. Further, EGR coolant outlet 36 and EGR coolant inlet 38 generally align with each other along the longitudinal direction of the body portion 80. EGR coolant outlet 36 and EGR coolant inlet 38 are also located to align with a coolant inlet and coolant outlet, respectively, of EGR cooler 16 (not shown).
(22) Appropriate fluid sealing systems may be provided at one or both of EGR coolant outlet 36 and EGR coolant inlet 38 of coolant collector bracket 18 to sealingly connect to the coolant inlet and exit of the EGR cooler 16. For example, EGR coolant outlet 36 and EGR coolant inlet 38 may include O-ring and/or other appropriate seals. In one arrangement, such as that shown in

(33) After positioning the coolant collector bracket 18 near the cylinder head 14, force is vertically applied onto the seat 54 to securely couple the jumper tube 56 of the coolant collector bracket 18 to the cylinder block 12. For example, a hammer may be used to apply force to the seat 54 to secure the jumper tube 56 to the cylinder block 12. The jumper tube 56 assists in the alignment of the distal end 45 of the exit leg. After securing the jumper tube 56 to the cylinder block 12, the cylinder head fasteners 52 associated with the top fastener connector 53 of the mounting legs 31 can be received by the bracket connection openings 70 of the cylinder head 14 to securely fasten the coolant collector bracket 18 to the cylinder head 14.
(34) Thus, the coolant collector bracket 18 described herein provides a number of features for facilitating assembly to the engine system 10. For example, the jumper tube 56 of the coolant collector bracket 18 facilitates alignment of the distal end 45 of the exit leg 39. The slots 65 (and corresponding slot openings 64) as described above, allow for the coolant collector bracket 18 to be slidably inserted onto the corresponding bottom fasteners 66 of the cylinder head 14. Further, the gaskets 58 of the coolant collector bracket 18 facilitate assembly by securely snapping in place on the mounting legs 31. Additionally, the vertical orientation of the EGR cooler 16 coupling to the coolant collector bracket 18 allows for the EGR cooler 16 to rest on top of the coolant collector bracket 18 during coupling. Specifically, as opposed to horizontally mounting the coolant collector bracket 18 from the side (which would require holding the EGR cooler 16 during coupling), the vertical orientation of the fastener connectors 50 of mounts 86 (
