Summary

Higher vehicle riding comfort demands have caused increasing production volume of balancer units in engines for middle and premium class vehicles. MAGNA Powertrain developing and producing mass balancer systems is permanently improving this mechanical engine component. The main advantage of balancing systems the reduction of vibrations is in direct conflict with high frequency acoustic phenomena. Extensive research programs have been founded to improve the noise behaviour. New simulation tools and material investigations have been carried out. A new dynamic simulation to analyse gear rattle noise will be introduced to evaluate the gear contact noise emission. The usage of materials like powder metal or plastics instead of steel has been investigated. Mass balancer unit as integral part in conjunction with oil pump, windage tray or ladder frame will be seen more often in the future. MAGNA Powertrain is introducing a new high speed oil pump for diesel as well as for gasoline engines. Based on the continuous improvement of the above mentioned engine components we can offer high end products globally to our customers.
