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.
