Low-friction crankshaft seal

  • 19-Mar-2010 03:05 EDT

Federal-Mogul’s MicroTorq low-friction crankshaft seals can directly replace existing seals to provide improvement in fuel economy and CO2 emissions, according to the company. The seals reduce friction by up to 70% vs. conventional lip-type seals. The MicroTorq can provide an improvement in vehicle fuel economy of up to 0.49% and a reduction in CO2 emissions of 1-2 gal/km (1-2 gal/mi) compared to traditional seal designs, the company claims. The seals are also easier to install, more accommodating of shaft misalignment or eccentricity, and require less package space. Benefits can be achieved relatively simply, even on existing engines, as the MicroTorq seal can be used without changing the design of adjacent components.
