In an internal combustion engine that includes a cylinder block and a cylinder head, and has a cam chain chamber on a side of the cylinder block, a beam member that traverses the cam chain chamber is disposed in the cam chain chamber.
First claim
Opening claim text (preview).
The invention claimed is: 1. An internal combustion engine comprising comprising: a cylinder head; a cylinder block including a cylinder chamber and a cam chain chamber each integrally formed in the cylinder block; and a beam member mounted in the cam chain chamber so as to traverse the cam chain chamber, wherein the beam member is arranged on an inner wall of the cam chain chamber at a portion in which a wall thickness between the cam chain chamber and the cylinder chamber is thinnest. 2. The internal combustion engine according to claim 1 , wherein the beam member is detachably mounted in the cam chain chamber. 3. The internal combustion engine according to claim 1 , wherein the beam member overlaps with extends laterally away from the cylinder chamber. 4. The internal combustion engine according to claim 1 , wherein the beam member includes a plurality of the beam members disposed in the cam chain chamber. 5. The internal combustion engine according to claim 1 , further comprising a cam chain arranged in the cam chain chamber, wherein the beam member is disposed within a winding of the cam chain. 6. The internal combustion engine according to claim 5 , wherein the cam chain defines two cam chain lines extending within the cam chain chamber along a rotation path of the cam chain, and wherein the beam member is disposed closer to a first cam chain line of the two cam chain lines. 7. The internal combustion engine according to claim 6 , wherein the first cam chain line is arranged on a side of the cam chain chamber that is opposite to a tensioner. 8. The internal combustion engine according to claim 1 , wherein the beam member is disposed adjacent to a mating surface between the cylinder block and the cylinder head.
