Litens Automotive’s heavy-duty overrunning alternator decoupler (OAD), which is based on proprietary technology installed in over 13 million light vehicles per year, is a new alternator pulley concept for heavy-duty and off-highway truck engines. Providing both overrunning and damping functionality through the use of a one-way clutch and spring, Litens’ OAD can result in significant improvements in vehicle fuel economy and FEAD system durability, the company claims. Litens’ analytical tools can be used to predict and simulate potential opportunities for a lean system approach. According to Litens, current applications have resulted with an up to 10x durability improvement and 30% reduction in belt tension when compared to the incumbent technology.
