    The INA chain drive – will the chain last the entire life of the car?

    The market share of engines with timing chains is set to increase significantly in the future. Currently, the ratio is about 50:50 (belts to chains). Industry experts predict that the chain will achieve around 80% share in 2030. Based on the assumption that around 30% of new registrations will be electric and the proportion of …

    Camshaft is not equal to camshaft

    Camshafts are manufactured in three different procedures. The design used most frequently is a camshaft manufactured from cast iron. The steel camshaft is another popular design. It is used when specific material is required. Here the camshaft is milled from a steel billet and then honed. The third design is known as the assembled camshaft. …

    The small dual-mass flywheel in the auxiliary drive

    The PYD decouples the belt drive from the rotational irregularities of the internal combustion engine, with a specifically designed arc spring isolating the belt pulley from the crankshaft. The PYD is mounted directly on the crankshaft. It usually also contains a torsional vibration damper, which is needed to limit the natural vibrations of the crankshaft …
