For the sake of solving the problem of great rotary inertia and forged steel rockerarms bad wear-resisting property in the engine of Xia Li cars with modelTJ370Q TJ376Q, we utilize the assembly theory of creative engineeringmethodology to respectively make the aluminum alloy materials and siliconnitride engineering ceramics as base stock of rocker arm and cabochon glut. Inthis way, the goodness of these two kinds of materials are fully strengthened. Forthe new rocker arms, their comprehensive property are enhanced and the cost ofmanufacture is lower than before.

为了解决夏利轿车发动机TJ370Q和TJ376Q中所装配的锻钢镀硬铬气门摇臂所存在的转动惯量大、圆弧面耐磨性差的问题，项目研制中运用创造性方法学中的"组合"原理，有针对性地选用铝合金和氮化硅陶瓷这两种具有不同性能特点的材料分别作为摇臂基体和工作圆弧面镶块，充分发挥两种材料各自不同的性能优势，从而达到提高产品综合性能，降低制造成本的目的。
