In order to meet expectations for higher-powered compact engines for automobiles, a new titanium alloy (Ti-6Al-4V, ti-6Al-6V-2Sn) connceting rod whose specific strength is greater than that of steel has been manufactured on a trial basis. A great weight saving can be achieved. The weight ratio of this titantium connecting rod compared to steel is from 65% to 80%. A full size fatigue test and engine test were conducted to evaluate the durability of this titanium connecting rod. As a result, its was verified that this titanium connecting rod has sufficient fatigue strength for automobile usage.
