Abstract
A cylinder block for an internal combustion engine is provided which includes a plurality of relatively spaced free-standing cylinder tubes disposed within a cooling jacket formed in the block. The cylinder tubes are connectedly supported by, and extend upwardly from, the floor section of the cooling jacket. The jacket floor section is reinforced by at least one elongated rib-like member which is integral with and depends from the underside of the floor section and is located between adjacent cylinder tubes. Each rib-like member substantially spans the distance between opposing walls that form, in part, the cooling jacket, and is remote from a cavity within the jacket through which a coolant is caused to circulate during operation of the engine. Bolt receiving means of the cylinder block are positioned so that, when restraining bolts are introduced and tightened to secure a cylinder head to the block, substantially uniform support of the cylinder tubes from their lower portion is achieved. Lateral movement of the upper ends of the cylinder tubes is restricted by struts extending radially from the cylinder tubes and connected to the walls of the cooling jacket.
