Abstract

A compound bracket system (400) for an internal combustion engine (100) includes a first bracket (112) that is rigidly connected to a crankcase (102) of the internal combustion engine (100). The first bracket (112) forms at least one mounting pad (310) that is arranged to connect to and support a first engine component (114). A second bracket (120) is connected to the crankcase (102) through at least one additional engine component (110). The second bracket (120) forms a component cavity (208) that is arranged to accept and support a second engine component (118). The first bracket (112) forms an interconnection pad (314), and the second component forms a strut (216) having a mounting tab (218). The mounting tab (218) is advantageously connected to the interconnection tab (314) with a fastener (422), thus increasing the rigidity of the second bracket (120) as mounted on the engine (100).

Claims

1. An internal combustion engine comprising:

a crankcase having a cylinder head connected thereto;

a turbocharger support bracket connected to a valley portion of the crankcase through a mounting flange that is formed on the turbocharger support bracket, wherein the turbocharger support bracket forms at least one mounting pad and at least one interconnection pad;

a turbocharger that includes a turbine that is operably associated with a compressor, wherein the turbine is connected to the turbocharger support bracket at the at least one mounting pad;

an intake manifold connected to the cylinder head;

an exhaust gas recirculation (EGR) cooler support bracket connected to the intake manifold, wherein the EGR cooler support bracket is connected to an EGR cooler;

an interconnection tab disposed on a strut, wherein the strut is connected to the EGR cooler support bracket, and wherein the tab is connected to the interconnection pad of the turbocharger support bracket.

2. The internal combustion engine of claim 1, wherein the EGR cooler support bracket comprises a first bracket portion having the strut integrally formed therewith, and a second bracket portion that is connected to the intake manifold, further comprising a band clamp disposed around at least a portion of the first bracket portion and the second bracket portion, wherein the clamp is capable of connecting the first bracket portion and the second bracket portion such that the EGR cooler is retained therebetween.

3. The internal combustion engine of claim 1, wherein the interconnection tab is connected to the interconnection pad with a fastener, wherein the fastener passes through a fastener opening in the interconnection tab, and wherein the fastener is threadably engaged with the turbocharger support bracket.

4. The internal combustion engine of claim 3, wherein a portion of a flange formed on the turbine is disposed between the interconnection tab and the interconnection pad.
