The European Union has set the goal of reducing overall CO2 emissions for newly registered cars to 95 g of CO2/km by the year 2020. Among other things, frictional losses in the engine and drive train must be reduced to achieve this objective. With the new Levitex seal, the loss of performance for a crankshaft seal is up to 95 percent less than for a standard PTFE seal. The remaining friction is solely due to air shear. This results in less fuel consumption, less wear and a longer service life. The CO2 emissions at the sealing point decline to less than 0.1 gram/km from 0.5 to 1 g under the NEDC (New European Driving Cycle).
