Abstract
In a fluid passage structure of an internal combustion engine wherein oil flows from an in-block flow passage formed in a cylinder block to an in-head flow passage formed in a cylinder head, a groove that is generally rectangular in cross section is so formed in a top face of the cylinder block as to extend from a position corresponding to an opening of the in-block flow passage formed in the top face to a position corresponding to an opening of the in-head flow passage formed in a bottom face of the cylinder head, by machining or the like. Thus, a flow passage arrangement in which the openings of the flow passages are offset from each other is allowed. As a result, the degree of freedom in designing the fluid passage structure is enhanced.
