A camshaft for an automobile engine is generally made of chilled case iron. But, because of increased demand for higher performance engines, a camshaft with many cam-faces has been expected. The cam intervals were necessarily narrow. So it was difficult to manufacture the conventional chilled cast iron camshaft at a moderate price. In the case of a rocker-arm type valve mechanism, higher wear resistance was necessary. After due consideration to solve these problems, development of surface remelted chilled layer camshafts by Toyota's unique manufacturing method has been accomplished. In this paper, the excellent wear resistance, the low manufacturing cost and the characteristic manufacturing method are described.
