鉴于CO_2排放目标不断加严,有必要进一步降低动力总成的摩擦损失。为此,不仅要降低发动机本身的摩擦损失,例如活塞组或轴承所引起的摩擦,而且还要降低辅助设备所消耗的摩擦损失。Mahle公司将摆杆滑盘式机油泵与真空泵组合成1个模块,使得机油泵具有高效和耐磨的特性曲线场调节优点,此外,还获得了减轻质量和改善结构空间方面的潜力。 In view of the increasing CO2 emission targets, it is necessary to further reduce the powertrain friction loss. For this reason, it is necessary to not only reduce the frictional losses of the engine itself, such as the friction caused by piston packs or bearings, but also reduce the frictional losses consumed by auxiliary equipment. Mahle combines a pendulum slide pump with a vacuum pump into a single module, which allows the pump to have the advantages of an efficient and wear-resistant characteristic curve field adjustment and the potential to reduce quality and improve structural space.
