An internal combustion engine includes: at least one magnet (10) inserted into at least one immersion container (8) present in the fuel tank (3), at least one magnet (20) applied on the cooling duct; at least one pair of magnets (30) arranged on the fuel duct, the fuel duct defining a coil; at least one pair of magnets (40) applied on the air suction pipe; and at least one pair of magnets (50) applied on the fuel filter, the magnets (10), (20), (30), (40) and (50) being permanent magnets including rare earth elements. The internal combustion engine includes at least one metal sheet (1) including paramagnetic and/or ferromagnetic elements applied on at least one portion of at least one internal surface (2) of the tank (3).

Disclosed are systems, methods, and algorithms for monitoring and indicating filter life. In particular, the disclosed systems, methods, and algorithms may be utilized for monitoring and indicating the useful life of a filter in an internal combustion engine.

A cleaning module (10) for cleaning a media flow of a first medium contaminated with a second medium that has a housing (12) having an inlet (18) and an outlet (20, 21) and a replaceable filter element (30) arranged within the housing (12). In this arrangement, a flow direction (32) of the media flow is directed through the filter element (30) in the specified installed state against the force of gravity. The filter element (30) has an absorptive and/or adsorptive material (34) for picking up at least a portion of the second medium in the first medium. A filter element for the cleaning module (10) and a filter system (100) having the cleaning module (10) are disclosed.

The invention relates to a device for reducing pollutant gas emissions by means of catalyst management in the combustion process, characterised in that it comprises: a hollow cylindrical body with a fuel inlet hole in one side of said cylindrical body and a fuel outlet hole in the other side of said cylindrical body; a perforated cylindrical separator inside said body; and a sheet formed by at least one magnetic element and which is situated between the perforated separator and the inner wall of the hollow cylindrical body, such that when the fuel flows inside the device, part of the components of the hydrocarbon magnetise.

A fuel supply system includes a fuel pump having an inlet configured to pick up fuel and an outlet configured to discharge fuel. A pressure vessel is in fluid communication with the outlet of the fuel pump such that fuel is directed from the fuel pump into the pressure vessel, the pressure vessel having an outlet port. A pressure regulation valve subassembly is detachably coupled with the outlet port via a male-female interface that positively locks against axial separation upon axial coupling in a first orientation and relative rotation of less than 360 degrees to a second orientation. A reservoir defines an internal space at least partially receiving the fuel pump, the pressure vessel, and the pressure regulation valve subassembly. The reservoir includes an interior wall that obstructs rotation of the pressure regulation valve subassembly from the second orientation to the first orientation.

The invention relates to a filter unit, a filter system (44b) with at least two filter units, and to a motor vehicle with a filter system (44b). A filter bowl (12d-e) of the filter unit is formed by a base and a cover. Embodied in a side wall of the base are at least two access openings to an antechamber or collection chamber (34a-b) in the filter bowl (12d-e). Embodied integrally with the cover is a collection line segment or supply segment (26d-e) that leads from a clean chamber or an unfiltered side antechamber in the filter bowl (12d-e) to at least two open ends (28l). The inventive filter system (44b) has at least two inventive filter units, and fluid may flow through their filter elements (30, 30a-d), which are switched in parallel. The invention facilitates the space-saving arrangement of filter units and filter systems (44b) in constricted and/or complexly shaped installation spaces, especially in motor vehicles.

A filter assembly for a fluid to be filtered, in particular fuel or oil, has a filter housing having a housing lower part that is configured as a single piece and has at least one fluid inlet for the fluid to be filtered and a plurality of filter pots that are arranged next to one another side by side in a shared plane and are fluidically connected to one another via side wall passages An upper housing part closes the filter pots and has a fluid manifold that has at least one fluid outlet for the filtered fluid flowing out from the filter pots. At least two filter elements, one being arranged in each of the filter pots of the filter housing. The filter assembly is a more inexpensively-manufactured and as configured for installation even in confined installation spaces, so as to accommodate a sufficiently large filter surface for a predetermined volume flow of a fluid to be filtered.

An engine operable in a premixed combustion system and a diffusion combustion system. The engine includes a main fuel injection valve, a pilot fuel injection valve, a liquid fuel tank, a main fuel supply path, a pilot fuel supply path, a pilot fuel filter, a pilot fuel high-pressure pump, a pilot fuel tank, and a pilot fuel supply pump. The pilot fuel tank stores pilot fuel sent from the pilot fuel high-pressure pump and not injected by the pilot fuel injection valve. This pilot fuel is sent to an automatic backwash filter and a pilot fuel filter while not passing through the liquid fuel tank.
