POLYTEC PASSION CREATES INNOVATION

Powertrain Solutions

POLYTEC PRODUCTS MEAN CLEANLINESS AND EFFICIENCY IN THE ENGINE COMPARTMENT

The Powertrain Solutions product series incorporates comprehensive competences for car and commercial vehicle engine compartments. Irrespective of whether cylinder head covers, oil separators, oil pans, air intakes, crankcase ventilation, covers, or fuel cell applications are involved, POLYTEC offers solutions that set new standards with regard to both the use of materials and engineering.

FUNCTIONAL INTEGRATION

WE REDUCE THE NUMBER OF PRODUCTION STEPS AND THUS SAVE COSTS

POLYTEC has established an excellent reputation through its innovative solutions for functional integration and the fact that considerable potential still lays dormant in the engine compartment is demonstrated by the oil pan of the Porsche 911 Carrera. In this case, by combining the functions of the air-oil separator, the switch box and the oil lines, POLYTEC not only reduced the complexity of the component, but also its weight.

 


Highlights:

  • A weight reduction of 36% as compared to the aluminium predecessor model

  • Cost reductions as a result of design freedom, functional integration, process reliability and reworking elimination

SYSTEM INTEGRATION

THE LINKAGE OF VARIOUS FUNCTIONAL ELEMENTS TO FORM A COMPONENT SYSTEM

Maximum precision and integrated design are of special importance in the engine compartment, in order to ensure that every available inch of space is used to optimum effect. For example, POLYTEC employs the advantages offered by hot gas welding to both integrate all the functional elements involved in crankcase ventilation and join highly complex geometries. System integration thus combines 55 individual parts, which include non-return valves, lines, gaskets and separation systems, to form a single, ready-to-install product.

 


​​​​​​​Highlights:​​​​​​​

  • Implementation of highly complex, three-dimensional welds

  • Prevention of the formation of loose particles or dust

  • Economic integration of all functional elements in a single, ready-to-install product

OIL SEPARATION

HIGHER CLEANING LEVEL AND LOWER COSTS

POLYTEC also sets benchmarks with regard to the cleaning of crankcase ventilation gases. In combination with a multi-level, suction jet pump, the group’s in-house developed, differential pressure controlled oil separator facilitates higher blow-by gas purity in both the idling and full load modes. As a result, our customers profit from simplified and more efficient combustion gas cleaning, the protection of the turbocharger against soot and reduced engine oil consumption, which permits longer intervals between servicing.

 


​​​​​​​Highlights:

Separator

  • Freely scalable and higher oil separation performance at lower cost as compared to disk separators

  • Clean combustion gases owing to extremely efficient oil mist separation

  • Universal plug & play separator (Otto and diesel engines)

Pump

  • Customisation possible

  • Electrical elements and drives are unnecessary

  • Universal applications: tank and crankcase ventilation, fuel cells ​​​​​​​

ACOUSTICS

STYLISH SILENCE

POLYTEC numbers among the innovators of PUR foam acoustic elements. In particular, with its patented one-shot process, the group has established a new industrial standard in the case of engine covers, which not only have to possess high levels of noise absorption, but also a perfect surface. Moreover, numerous additional customer demands relating to acoustic components for (battery driven) e-vehicles have already been realised through the ongoing further development of the PUR foam process.

 


​​​​​​​Highlights:​​​​​​​

  • Improved acoustic performance at lower cost as compared to conventional engine covers

  • Optimised head-impact performance

  • Attractive design possibilities

  • Noise optimisation in e-vehicles
