Recent Development in Heavy Duty Engine Air Filtration and the Role of Nanofiber Filter Media

The development of an engine air filter is based on filter performance requirements, vehicle’s operational environment, available space, filter media properties, and production technology. The design process includes analyses of theoretical and empirical models describing filter media performance and aerosol flow in filter housings and through filter elements. Filter media are carefully selected based upon these models and simplified laboratory tests. The filter element design is evaluated in great detail through a series of laboratory and field experiments.

Nanofiber Media Performance in Application to Motor Vehicle Air Filtration

The function of air filtration systems in motor vehicles is to improve air quality and cleanliness in car interior, control the respirable particle concentration in the operator’s cabin, and reduce the dust concentration in the engine intake air to an acceptable level. In these applications, limited space is available for the air filtration systems. Therefore, filters are designed in smaller packages, resulting in higher aerosol velocities through the filters. Such high aerosol velocities may cause dust reentrainment leading to an increase in the amount of dust penetrating the filter. Moreover, motor vehicle environments are extremely varied and these environmental and operational conditions influence filter performance.

Overview of Nanofibers Applications for Air Cleaning

The Need for Air Cleaning Air filtration intake systems perform a number of functions including reducing intake noise and removing moisture. Clean air is needed to prevent wear of moving parts and prevent workers in high dust environments from developing respiratory problems. All of air contaminants entering equipment can and will lead to unnecessary wear, shorter machine life, and increased maintenance costs.
