Successful application of crankcase ventilation (CV) systems to diesel engines is critical for engine manufacturers to meet future emission requirements. This paper discusses the challenges associated with filtering crankcase blow-by and explains the technical considerations for designing a CV system for specific engine platforms. The paper also compares the performance of CV systems from various filter manufacturers using common performance metrics and presents our approach for optimizing CV system design to support diesel engine manufacturers' efforts to meet emission requirements of 2007 and beyond.
