Adaptive Oil Separation for Efficient Crankcase Ventilation

Dipl.-Ing. (FH) Francesco Zitarosa is Director of the Global Crankcase Ventilation Application Technology Department at the Reinz-DichtungsGmbH in Neu-Ulm (Germany). Philipp Zedelmair, B. Eng. works on Oil Separation Development at the Plastics Systems Division of the Reinz-DichtungsGmbH in Neu-Ulm (Germany). Dipl.-Ing. (FH) Christoph Erdmann is Development Director at the Plastics Systems Division of the Reinz-Dichtungs-GmbH in Neu-Ulm (Germany). Dr. Jürgen Schneider is the Director of the Product Development Europe Department at the Reinz-Dichtungs-GmbH in Neu-Ulm (Germany). The trend towards combustion engines with increasing mean pressures results in oil particles in the blow-by gas which are finer and finer. Oil separation systems separate these fine oil particles out of the blow-by gas, thus fulfilling an important function in the crankcase ventilation. With its new Multitwister technology, Reinz has expanded the oil separator by adding an adaptive solution which actively influences the pressure curve and increases its efficiency even further.
