摘要: Over the years rocker arms have been optimized in its design and material for better performance. Durability, toughness, high dimension stability, wear resistance, strength cost of materials as well economic factors are reasons optimization arm. This paper reviews various types arms, based on published sources from last 40 order to understand arm problem identification further optimization. present what is, where it is used why used, History related working described. Various vehicles different making studied this paper. Reasons Failure also discussed
