An air filter element for an air filter may include a first end plate and a second end plate spaced apart from each other in an axial direction and configured to bound the filter element in the axial direction. The first filter body may be arranged axially between the first and second end plates. A second filter body may be arranged axially between the first and second end plates. An intermediate plate may be arranged axially between the first and second filter bodies and have an intermediate plate area enclosed by an intermediate outer contour and a first end plate area enclosed by a first outer contour.

Air filter element

A filter element may include a first end disc, a second end disc, a filter medium arranged between the first and second end discs, wherein the first and second end discs are spaced by a filter medium. A third end disc may connect the first and second end discs and be arranged obliquely to at least one of the first end disc and the second end disc. The third end disc may include at least one of an inlet and outlet.

Filter element, in particular air filter element

A catch box may include two air intake sections of an air intake system, wherein the catch box is embodied as water separator at the same time.

Catch box

The invention relates to a device () for ventilating a crankcase of an internal combustion engine, comprising a ventilation line leading from the crankcase to the suction line of the internal combustion engine, an oil-mist separator () for separating the oil parts from the blow-by-gases containing the oil-mist from the crankcase is arranged in the path thereof. Also, said device () comprises a pump () which is arranged upstream of the oil-mist separator () and which is used to produce a negative pressure. The invention is characterized in that the oil-mist separator () and the pump () are embodied as connected modules thus providing a particularly compact structure.

Device for ventilating a crankcase

A positive crankcase ventilation oil mist separator system has a first separator unit, wherein the first separator unit includes at least one filter body arranged in a blow-by gas path such that blow by gas flows through the filter body; a second separator unit, wherein the second separator is an impactor separator arranged in a bypass path that bypasses the first separator unit; and a bypass valve, which opens the bypass path as soon as a differential pressure at the first separator unit exceeds a predefined value, wherein the second separator unit comprises an impact wall formed by a section of the filter body of the first separator unit, and a flow directing element which directs the blow-by gas flow against the impact wall when the blow-by gas path is open.

Oil mist separator

The invention relates to a device for separating a gas-liquid mixture, in which the liquid portion exists in the form of small particles, especially for ventilating a crankcase of an internal combustion engine, by separating and coagulating the liquid particles on a target area. The liquid mixture, after acceleration in acceleration openings provided for this purpose, impacts the target area at an approximately right angle. The aim of the invention is to improve the aforementioned device in such a manner that it allows as high a degree of separation as possible for different sized volume flows of mixtures. For this purpose, the number and/or the cross-sections of the acceleration openings is varied, depending on the volume flow of mixtures, between a small complete cross-section for a low volume flow and a large complete cross-section for a large volume flow.

Device for separating a gas-liquid mixture

A centrifugal oil mist separator device integrated into an axially hollow camshaft of an internal combustion engine should permit a good separation effect. To this end, a device is provided whereby
