“…Reducing the pressure drop through the air filter element, and thus improving engine performance, was the subject of macroscopic optimization and geometric parameter studies of the fibrous pleated filter element. According to the conducted studies, a pleated filter bed with fixed geometric parameters (pleat height and width, pleat spacing) is characterized by the optimal number of pleats at which the minimum pressure drop was recorded [ 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 ].…”

“…In the paper [ 60 ], the results of a numerical study of cellulose filter beds with different shapes (flat, W-shape and sinuous shape) were presented. It was shown that the filter element with a sinusoidal shape has a lower pressure drop, a more uniform distribution of the flow field and a smaller space size, which is the optimal solution.…”

The material most commonly used to filter and clean the intake air of vehicle internal combustion engines is pleated filter paper, which in most cases is shaped in the form of a cylinder or panel. The production technology has a low cost and is not complicated. In addition to high separation efficiency and filtration performance, pleated filter media are required to have low initial pressure drop, which depends on the geometry of the bed. Much research has been conducted in this area. Dust accumulated in the filter bed causes an increase in pressure drop, which is the cause of deformation and sticking of pleats. The lack of stability of the pleats, the need to strengthen them, and the need to obtain small sizes while achieving high efficiency and accuracy of filtration of engine intake air was the reason for the development of a different design and a new technology for making filter cartridges called PowerCore. The distinctive feature of these filters is axial flow in one direction of the air stream, which avoids turbulence and thus minimizes pressure drop. This paper presents a comparative analysis of a standard PowerCore and PowerCore G2 filter bed and two cylindrical filters with a pleated filter bed made of cellulose and polyester. The conditions and methodology of experimental testing of filters with test dust are presented. During the tests, the characteristics of separation efficiency and filtration performance, as well as pressure drop as a function of the mass of dust retained on the filter of two PowerCore filters and two cylindrical filters were performed. Three specimens of test filters with the same filtration area were made from each sample of filter bed. The results showed that in each test of the filter bed, there is an initial filtration period characterized by low (96–98%) initial separation efficiency and the presence of large (dpmax) dust grains. As the dust loading of the bed increases, the separation efficiency and filtration performance obtain higher and higher values. The initial period of filtration ends when the conventional value (99.9%) of separation efficiency is reached. The duration of this period depends on the type of filter bed and for the PowerCore G2 filter ends for a dust loading of km = 33.1 g/m2, and for the cellulose filter for km = 117.3 g/m2. During the initial period, the air behind the PowerCore G2 filter contains grains with sizes in the range of dpmax = 9–16 µm. Behind the cellulose filter, dust grains are much larger, dpmax = 17–35 µm. The total operating time of the PowerCore G2 filter, limited by the achievement of the permittivity resistance Δpwdop = 3 kPa, is twice that of the other filter compositions tested.

Filter materials with structural stability and high-temperature resistance are urgently needed in the field of industrial exhaust gas filtration. Here, an Al 2 O 3 porous ceramic with a biomass porous structure and thermal stability (above 1500 °C) was developed using a cost-effective and a readily available feedstock sacrificial biomass template method and subsequent calcination. Al 2 O 3 porous ceramics from the sacrificial biomass template method exhibit better filtration capacity for air than general porous alumina ceramics; this can be attributed to the porous structure of Al 2 O 3 -PCBT, which increases the contact area and the number of contact points between the PM particles and the pores. In addition, the Al 2 O 3 -PCBT filter cartridge specimens showed high filtration efficiencies (up to 95.20 %) and a low-pressure drop (down to 400 Pa) for the ultrafine CaCO 3 particles at an air velocity of 4.5 -10 m•s -1 . We envision that the Al 2 O 3 -PCBT filter will provide a solution for the removal of the particulate matter from industrial high-temperature exhaust gases.
