How does the crankcase ventilation filter improve the engine?
• Tier 4 Interim requires that crankcase emissions, also known as blowby gasses, be included in the overall regulated engine emissions. To control blowby gas emissions, Cummins engines incorporate a highly efficient coalescing filter. The filter returns the oil to the crankcase and provides the added benefit of removing oil mist and tiny oil droplets, ensuring that the engine and powertrain remain cleaner than at Tier 3. The crankcase filter requires a simple filter element change at 2,500 hour intervals.
