A filter element for a filter device may include a support structure extending along an axial direction, on which on a circumference side an annular filter medium consisting of filter material may be arranged, and an annular first end disc having a passage opening through which a first pin element may be passed, so that the first pin element may project out of the passage opening along the axial direction, wherein a second pin element may axially project from the first end disc laterally spaced apart from the first pin element.

The lubrication mechanism comprises a vertically disposed crank shaft, a laterally movable piston, a connecting rod connecting the crank shaft and the piston, a cylinder barrel housing the crank shaft and the piston, a crank case containing the crank shaft together with the cylinder barrel, a cylinder head forming a combustion chamber, the combustion chamber connecting to a piston movable part end face of the cylinder barrel, an oil filter, and an oil filter installation member in which the oil filter is vertically installed, and the oil filter installation member includes a lubricant detour structure.

An engine oil receiving structure comprises a vertically disposed crank shaft, a laterally movable piston, a connecting rod connecting the crank shaft and the piston, a cylinder barrel housing the crank shaft and the piston, a crank case containing the crank shaft together with the cylinder barrel, a cylinder head forming a combustion chamber, the combustion chamber connecting to a piston movable part end face of the cylinder barrel, an oil filter filtering engine lubricant, and an oil case storing oil flowing out when the oil filter is removed from a mounted position, and the oil case is fixed to an engine under the oil filter, and comprises a discharge path to discharge the stored oil.

One or more techniques and/or systems are disclosed for a vehicle fluid filter head. The filter head can be attached to two or more filters to filter vehicle fluid, and provide a variety of optional arrangements for coupling inlet and outlet hoses. A plurality of inlets and outlets can be disposed on the filter head at different sides of the filter head. A pair of filter headers can be disposed on a first side to receive filter. A first inlet and outlet can be disposed on a second side, and a second inlet and outlet can be disposed on a third side. Respective inlet are fluidly coupled with an inlet passage in the head, which is fluidly coupled with an intake portion of the filter headers. Respective outlets are fluidly coupled with an outlet passage in the head, which is fluidly coupled with an outflow portion of the filter headers.

An exchangeable filter system is provided with an exchangeable filter module that has at least one fluid inlet, at least one fluid outlet, and a fluid path connecting the at least one fluid inlet and the at least one fluid outlet with each other. The exchangeable filter module is provided with at least one filter element for filtering a fluid. A flange element and a counter flange element are provided. The flange element is provided to releasably engage the exchangeable filter module and to releasably engage the counter flange element. A valve device is arranged in the flange element. The valve device blocks the fluid path when the flange element is in engagement with the exchangeable filter module and is disengaged from the counter flange element. An internal combustion engine is provided with such an exchangeable filter system to filter fuel, lubricant or urea.

An easily serviceable liquid filter assembly having a housing with a drain to provide draining of fluid (e.g., liquid) from the housing. The filter assembly has a fluid inlet to receive dirty fluid into the housing, a fluid outlet to expel filtered fluid from the housing, and a drain, when open, to expel unfiltered (dirty) fluid from the housing. By removing a cover from the housing, the filter element opens the drain so that all fluid in the housing can be directly collected or can flow into the oil pan to be collected with the fluid present in the pan. All fluid, now in the drain pan, can be drained and collected in a disposable container such as a plastic pouch, which can be recycled. The filter element can be removed from the housing via the removed cover.

The invention relates to an aerosol separator for separating aerosols in a blow-by gas, which comprises at least one feed opening for feeding a blow-by gas provided with aerosols, an outlet opening for discharging a blow-by gas cleaned of aerosols, at least one outflow opening for releasing aerosols removed from the blow-by gas, and which is arranged between a flow path of the at least one feed opening and the outlet opening, and a plurality of projections for configuring the flow path running from the at least one feed opening to the outflow opening in a meandering manner, in order to decelerate the blow-by gas which enters the feed opening and which is provided with aerosols, in terms of its flow rate. The separator is characterized in that the projections in their end region, around which blow-by gas flows, have a portion with increasing projection width.

There is provided an installation structure for an oil pressure sensor, including: a crankcase in which a main gallery that extends in one direction is formed; and the oil pressure sensor detachably installed on an outer surface of the crankcase. The oil pressure sensor is configured to detect an oil pressure of a branch passage branching from one end of the main gallery. In a bottom view of a vehicle, a connector of the oil pressure sensor is oriented to an outside of the vehicle, and the connector of the oil pressure sensor overlaps with the crankcase.

An oil filter arrangement for filtering oil of a vehicle can comprise: at least one filter unit for filtering the oil, and at least one connection unit comprising at least one inlet tube configured to be connected with an outlet tube of a separate oil pump, wherein the oil filter arrangement is configured to be housed in an oil filter arrangement housing of the vehicle.

Various methods and systems are provided for an oil filter system for a vehicle system. In one example, an oil filter system comprises a housing within which a plurality of oil filter elements are disposed and a frame supporting the housing, the frame including one or more mountings configured to support one or more vehicle sub-assemblies.
