The world of mobility is changing. For the two-degree target specified by the Paris Agreement to be achieved, a mix of all-electric drives, hybridised drives, and eco-friendly drives based on internal combustion engines is absolutely essential. <\/p>\n\n\n\n

Schaeffler<\/a><\/strong> predicts that the internal combustion engine will also continue to play a decisive role in the future. In the year 2030, internal combustion engines will still be installed in around 70% of vehicles \u2013 of which 30% will rely solely on the internal combustion engine and 40% will be hybrids. It is therefore essential for the further development of conventional drives to continue.\u00a0<\/p>\n\n\n\n

\u201cThe solutions that we will be presenting at the IAA make fuel savings of up to 15% possible depending on the engine and vehicle class,\u201d explains Matthias Zink, CEO Automotive OEM at Schaeffler. \u201cWe are giving our customers a lot of leverage with which to fulfill the strict legal requirements and reduce CO2 emissions during real operation as well.\u201d<\/p>\n\n\n\n

Valve train variability<\/strong><\/p>\n\n\n\n

At the IAA, Schaeffler will be presenting the latest version of its fully variable UniAir valve train system. As well as being more compact, this system is also 30% lighter than the previous version, and it allows the air path in the engine to be fully optimised and maximum dynamics achieved when load and speed changes occur. <\/p>\n\n\n\n

The system comprises a module that is installed between the camshaft and the valve stem, together with the relevant software. <\/p>\n\n\n\n

As a strong partner to the automotive industry, Schaeffler uses its comprehensive expertise in thermodynamics to help its customers optimally match the system to the relevant engine and select the corresponding operating strategies.<\/p>\n\n\n\n

Schaeffler\u2019s eRocker solution is designed for the exhaust side. The system\u2019s electromechanical actuation makes it independent of the engine\u2019s oil circuit, and it can also be applied with relative ease.<\/p>\n\n\n\n

Schaeffler will be presenting a further highlight with its electric cam phasing (ECP) unit. This system makes rapid adjustments based on the speed and temperature and allows the valve timing to be optimised throughout the entire operating and temperature range, which plays an increasingly important role when it comes to hybridisation since internal combustion engines in hybrid vehicles have to be started with significantly greater frequency than those installed as the sole drive source. <\/p>\n\n\n\n

The electric camshaft phasing unit ensures that this start process takes place quickly, efficiently, and most importantly, with low vibration levels.<\/p>\n\n\n\n

48V hybridisation makes fuel savings of up to seven per cent possible<\/p>\n\n\n\n

Hybridisation supports the internal combustion engine while reducing its workload and, in conjunction with braking energy recuperation, improves the overall efficiency of the system. <\/p>\n\n\n\n

At the IAA, Schaeffler will be demonstrating 48V hybridisation using a belt-driven starter generator, which allows a significant reduction in fuel consumption and emissions of 5 to 7% to be achieved. This type of solution enables comfortable and efficient start-stop operation of the engine and can also be configured for boost operation.<\/p>\n\n\n\n

Thermal management module<\/strong><\/p>\n\n\n\n

Thermal management is another key element when it comes to increasing efficiency. Schaeffler\u2019s individually adjustable thermal management module (TMM) for internal combustion engines and hybrid and electric drives provides enhanced control of the operating temperature throughout the entire powertrain, including the engine, transmission, and electrical components such as the battery, power electronics, and electric motor. <\/p>\n\n\n\n

The module allows precise regulation of volume flows using electromechanically powered rotary slide units that are controlled by position sensors. <\/p>\n\n\n\n

Alongside reduced CO2 emissions, the shorter warm-up phase also has another positive side effect: passenger comfort is increased.<\/p>\n\n\n\n

Less friction inside the engine<\/strong><\/p>\n\n\n\n

Even conventional bearing solutions still improve drives based on internal combustion engines: innovative solutions for rolling bearing supports in balancer shafts, camshafts, and crankshafts offer considerable potential for reducing power losses in the engine and thus for improving fuel economy and lowering emissions. <\/p>\n\n\n\n

Balancer shafts with rolling bearing supports generate approximately 50% less friction compared with shafts supported by plain bearings, for example. <\/p>\n\n\n\n

Schaeffler has also succeeded in developing an optimised design for balancer shafts that is up to 40% lighter without any loss of function.<\/p>\n","protected":false},"excerpt":{"rendered":"
