Industrias Dolz, with nearly 90 years of experience in the Aftermarket industry, continues developing its strategy of auxiliary drive kits for the automotive aftermarket. The full range includes all the necessary components for a professional assembly: poly-V belt, the auxiliary drive belt<\/a> tensioner and deflection pulleys necessary for each application.<\/p>\n

Dolz has launched the Auxiliary Drive Kit SKD250A<\/strong> suitable for hybrid vehicles equipped with a DW10 HY Hybrid engine and a BSG<\/strong> (belt start generator) system.<\/p>\n

In this article, we focus on the operation of the auxiliary drive belt tensioner of this kit and its features. Keep on reading to find out more.<\/p>\n

Auxiliary drive belt tensioner<\/h2>\n

 <\/p>\n

As mentioned earlier, the drive belt tensioner is a high precision element designed, as its name suggests, to optimize the tension of the accessories belt and prevent future breakdowns in the other elements such as the alternator or the water pump. It also dampens vibrations caused by changes<\/strong> in engine load or auxiliary drives.<\/p>\n

This new DOLZ tensioner allows the accessories belt to be maintained with the correct tension in both BSG system operating modes,<\/strong> both in its standard function where the poly-V\/serpentine belt drives the alternator, and in the starting mode of the engine.<\/p>\n

 <\/p>\n

BSG (Belt Starter Generator) System<\/h2>\n

 <\/p>\n

The BSG (belt-starter generator) system is designed to enable alternator torque to be transmitted alternately, in different directions. Through the poly-V belt, enables start-stop functionality, energy recovery when coasting or braking, and allows reducing\u00a0fuel consumption and\u00a0emission\u00a0of\u00a0CO2 by\u00a0improving the alternator efficiency.<\/p>\n

Thanks to its design, can take advantage of the different acceleration phases. So, when the vehicle is in energy recovery, the BSG operates as a generator that provides reverse power flow back to the battery.<\/strong><\/p>\n

SKD250A Kit: Advantages of Drive Belt Tensioner<\/h2>\n

 <\/p>\n

This poly-V belt tensioner is characterized by its dynamism, since it can optimize and adapt the tension based on the demands of the engine. As engines have grown more powerful, their energy requirements have increased as well. That’s why more complex components are required, capable of responding to current demands. Therefore, among the main advantages offered by the new DOLZ auxiliary belt tensioner we find:<\/p>\n
