Tech Brief
Crankcase ventilation (CCV) systems:
Are your materials limiting your safety and sustainability performance?

What you will learn in this tech brief:

Audience: design engineers, automotive manufacturers

Summary: The automotive industry is facing stricter regulations to clean up global pollution levels by reducing vehicle emissions. In fact, new emission performance standards are requiring auto manufacturers in China and the EU to use more advanced filtering and venting systems for particulate matters and for trapping exhaust gases to minimize the carbon footprint of vehicles using diesel, CNG, LGN and hydrogen engines. In addition to having negative effects on human health and the environment, ineffective filtration of blowby gases in the crankcase can lead to engine failure and premature degradation of components. As a result, auto manufacturers will need to look for innovative solutions that keep vehicles running with greater efficiency, safety and sustainability. In this tech brief you will learn how high-performing porous polymer media used in closed crankcase ventilation (CCV) system filtration can help manage critical fluids and gases, ultimately enhancing vehicle performance, driver safety and sustainability metrics—and as a result, manufacturer reputation.

What registrants will learn in this tech brief:

  • Understand the challenges and risks associated with poor material performance in CCV systems that are contributing to air pollution
  • Discover how a functional CCV system can relieve pressure in a crankcase, preventing airborne dust, particles, hydrocarbons and problematic gases from being released into the atmosphere while recycling oil within the combustion process
  • Learn why proper CCV system filtration can help maintain oil levels that protect engine components, maintain high engine performance and promote engine life
