The new Porex CCV filter for closed crankcase ventilation systems offers automotive manufacturers a filtration technology that improves engine life and complies with environmental legislation limiting greenhouse gas emissions.

The Porex CCV filter effectively removes oil mist and particulates from crankcase blow-by gases, prevents clogging and allows for lower pressure drops to improve vehicle efficiency. It helps lower vehicle emissions of nitrogen oxides (NOx), hydrocarbons and other harmful gases so that manufacturers conform more easily to EURO VI, China VI-a and VI-b, LEV III, Tier IV Final and BS VI emission standards.

Automotive manufacturers utilise closed crankcase ventilation systems to relieve pressure in engine crankcases caused by blow-by gases. These systems remove airborne dust, particles, hydrocarbons and other problem gases and prevent them from being leaked into the atmosphere. A CCV system also captures usable gases and oils to be reused within the combustion process, improving an engine’s performance. The Porex CCV filter is engineered from direct-formed bound fibres that offer greater filtration efficiency and resilience compared to competitive fiberglass filters. It effectively removes 96.4% of oil mist and particulates >0.3µm from hot crankcase blow-by gases.
