Abstract
A connecting rod of an internal combustion engine, formed from a light alloy such as aluminum, has a rod portion which is selectively and locally reinforced with bundle of inorganic fibers such as stainless steel fibers. The fiber-reinforced part of the connecting rod is suitably selected in accordance with the shape and function of the connecting rod. Assuming that the axis parallel to the axis of piston pin is represented by Y and the axis orthogonal to the axis Y by X, the second moment of inertia around the Y axis is smaller than that around the X axis at any cross-section of the rod portion. At the same time, in the fiber-concentrated part of the rod portion, the second moment of inertia around the Y-axis is selected to be equal to or greater than that around the X axis.
