Automotive Filter Technology from Porex Reduces Vehicle Emissions and Optimizes Engine Performance

Porex to share new filtration technology at SAE International’s WCX Digital Summit on April 13

(Atlanta, GA – April 12, 2021) Porex, a global leader in porous polymers, offers automotive manufacturers a unique filtration technology that improves engine life and compliance with environmental legislation limiting greenhouse gas emissions. The POREX® CCV Filter for closed crankcase ventilation (CCV) systems effectively removes oil mist and particulates from crankcase blow-by gases, prevents clogging and allows for lower pressure drops to improve vehicle efficiency. Offering superior aerosol filtration, the POREX CCV filter 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 utilize closed crankcase ventilation systems to relieve pressure in engine crankcases caused by so-called 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 fibers 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.

“A closed crankcase ventilation system is a critical tool in reducing harmful gas emissions and helps automotive manufacturers comply with new and more stringent environmental legislation,” said Judith Sebastian, Sr. Market Development Manager at Porex. “The POREX CCV filter is the secret weapon that optimizes these ventilation systems by offering a cost-effective solution for lowering emissions while improving engine efficiency, performance and longevity.”

Sebastian will discuss the impact materials can have on CCV systems with regards to safety, sustainability and performance at SAE International’s upcoming WCX Digital Summit Technical Program from April 13 to 15. Her presentation, “Crankcase Ventilation Systems: Are your materials limiting your safety, sustainability and performance?” will be part of the April 13 On-Demand Technical Session: Advances in Particulate Filter Substrates (Session Code: PFL423).

As manufacturers endeavor to comply with new emission standards, more sophisticated closed crankcase filtration technologies are needed to capture, filter and coalesce finer particles and return them to engine intake systems. The POREX CCV filter offers optimized pore size filtration that is compatible with higher-viscosity fuels commonly used in today’s automobiles. Porex’s low pressure filter design enhances vehicle efficiency because it facilitates even and consistent oil pressure regardless of a vehicle’s varying speeds and driving conditions. This consistency also improves performance and extends the life of the filter. Using Porex’s higher quality filtration media will also help reduce costly engine maintenance repairs and downtime.

Automotive designers can also take advantage of the POREX CCV filter’s small footprint which enhances design flexibility, reduces filter housing costs and increases engine cavity space. Porex delivers its filters pre-treated and fully formed, saving manufacturers time and effort compared to the assembly and treatment requirements for sheet-supplied filtration media. The design reduces part-to-part variability to ensure consistency in operation. POREX CCV filters can be customized to specific requirements for dimensions and performance needs, including oleophobic treatment options to extend filter life.
