Abrasive particles entering an engine because of inadequate air filtration can cause excessive wear, which may lead to premature engine failure. Despite the importance of filtration in engine systems, there is little understanding of the dynamics of the filtration process. Often, limited space is available for an engine air induction system. Therefore, filters are designed in smaller packages, resulting in higher aerosol velocities through the primary filter material. High aerosol velocities may cause dust reentrainment and increase the amount of dust penetrating the filter. Our experiments with cellulose and synthetic-type filter media show examples of dust reentrainment for fine and coarse dust. Conditions for dust particle reentrainment are discussed. In addition to dynamic filter performance associated with dust loading, reentrainment and seepage of dust particles, this paper reviews vehicle operating environments as they pertain to engine wear and filter performance.
