The invention relates to a tank assembly (5) having a tank container (10), a swirl pot (20) and an eductor pump (30), wherein a nozzle (32) of the eductor pump (30) is arranged on an upper side (16) of the tank container (10) at a distance above a swirl pot opening (22) of the swirl pot (20).

A mixing apparatus for producing a fuel/water mixture for an internal combustion engine includes a fuel line, where via the fuel line a combustion chamber of the internal combustion engine is suppliable with fuel, a connecting region, a water line which opens into the fuel line in the connecting region where via the water line water is introducible via the connecting region into the fuel line and is mixable with the fuel, and a valve arrangement which is disposed on the water line. The valve arrangement prevents an entry of the fuel from the fuel line into the water line when a pressure of the fuel in fuel line is higher than a pressure of the water in the water line.

A hydrogen intake assembly for a hydrogen internal combustion engine characterized in that the hydrogen intake assembly includes at least one air intake manifold comprising an air intake pipe comprising at least one air inlet and air outlets, air intake runners comprising air inlets and air outlets, a spacer having a wall defining an inner chamber receiving a mixture of air, water and hydrogen and comprising air inlets and mixture outlets delivering said mixture, a water rail comprising at least one water inlet and water outlets, said water outlets being embedded in the wall of the spacer and a hydrogen rail comprising at least a hydrogen inlet and hydrogen outlets.

An internal combustion engine includes a crankcase and a cylinder head. The cylinder head and the crankcase delimit at least one cylinder in which a translationally moving piston is arranged. A water injection device injects water into the at least one cylinder. A crankcase ventilation device is fluidically connected to the crankcase. A blow-by mixture containing injection water can flow through the crankcase ventilation device. The crankcase ventilation device has an activated charcoal filter. The blow-by mixture containing the injection water can flow through the activated charcoal filter.

A component, which can be in the form of a fuel line or fuel distributor, is used for a fuel injection system, which is used for injecting fuel or a mixture of fuel and water having a variable water content. The component has a main body on which is provided a high-pressure inlet and at least one high-pressure outlet, the fuel, respectively the mixture being passable from the high-pressure inlet through an inner space of the main body to the least one high-pressure outlet, and an insertion member being configured in the inner space. The insertion member is at least partially made of at least a material having a modulus of compression specified to at least substantially correspond to or be lower than that of the fuel, respectively the mixture and/or lower than 30 GPa.

A device for injecting water into a combustion chamber or into an intake tract of an internal combustion engine includes a rail and at least one injection valve connected to the rail. The connection is produced by means of a rail cup, which surrounds the injection valve at the rail-side end of the injection valve. The injection valve has a feed channel open toward the rail, in which feed channel at least some portions of an insert are received in order to reduce the feed cross-section.

A vehicle including an engine; a turbocharger, an intake air flow path of the vehicle defined from air entering the vehicle, passing through the compressor, and flowing into the engine air inlet; a coolant container assembly; a temperature sensor configured for determining a temperature in the intake air flow path; and a controller configured to selectively cause cooling liquid to flow from the coolant container into the intake air flow path. A method for managing engine air intake temperature or piston temperature of a turbocharged vehicle including: sensing a temperature of fluid within the air intake flow path, determining an estimated piston temperature; and in response to the estimated piston temperature and/or the temperature of the fluid being above threshold temperatures, causing an amount of cooling liquid to flow from a coolant container to the air intake flow path.

A method for determining an air mass in an air separator of a water direct injection system for injecting a water/fuel mixture into a combustion chamber of an engine of a motor vehicle. The air separator is disposed between a water pump for delivering water of the water/fuel mixture and a high-pressure pump for feeding the water/fuel mixture to a high-pressure injector for injecting the water/fuel mixture into the combustion chamber. The method includes increasing a pressure of the water from a first pressure value to a second pressure value by the water pump, determining a water volume delivered by the water pump during the increasing of the pressure of the water by the water pump, and determining the air mass in the air separator on a basis of the determined water volume delivered by the water pump.

The insertion member is at least partially made of at least a material having a modulus of compression specified to at least substantially correspond to or be lower than that of the fuel, respectively the mixture and/or lower than 30 GPa.

A water-conveying module for injecting water into a combustion chamber of an internal combustion engine, having a conveying unit, which has a pump for conveying the water from a tank. The water can be conveyed by the pump to an injection point along a dosing line. The conveying unit has a water outlet through which water is conveyed out of the conveying unit. The water outlet is formed by a connection plug onto which the dosing line can be plugged, Water can be conveyed from the conveying unit into the dosing line along the connection plug that has a section which can be flowed through by the water and which is part of the fluid line from the conveying unit to the dosing line.
