블로바이 가스 내 오일입자들을 제거하기 위한 필터의 유동특성 수치해석

Numerical Analysis of Flow Characteristics of the Filter for Separating Oil Mist from Blow-by Gas

초록

This research was performed to determine the oil separation characteristics of the specially designed oil filter installed in a PCV cylinder head passage. The oil filter was specially designed with fleece for separating oil mist from blow-by gas. The fleece, made of fiber fabric material, is placed in the oil filter case to absorb oil mist with a small pressure drop during blow-by gas through the filter. To do this, 3-D CFD analysis was simulated for the simplified PCV system with the oil filter using the commercial code, Ansys CFX. Results showed that the oil filter’s efficiency with fleece sharply increased as oil droplet size increased.
