摘要

For automobile engines, low fuel consumption and low emission technologies have been pursued while overcoming the difficulties such as two "oil-shocks", emission gas and CAFE regulations on Japanese automobiles. In addition, low noise and highperformance requirements are increasing recently. In this paper, it is introduced that the high strength and light-weighted Connecting Rod development and usage status in Toyota, along with the selection between Powder Forging and Forging.
