A fuel pump for a liquid fuel water injection system of a motor vehicle is provided. The fuel pump includes a low-pressure pump that mixes water from a water tank of the motor vehicle with liquid fuel from a fuel tank of the motor vehicle to a liquid fuel water emulsion and provides the liquid fuel water emulsion at a low pressure. A high-pressure pump is in fluid communication with the low-pressure pump and compresses the liquid fuel water emulsion from the low pressure to a high pressure for injecting the liquid fuel water emulsion into an internal combustion engine of the motor vehicle via an injection rail of the motor vehicle. A pump drive drives the low-pressure pump and the high-pressure pump synchronously with a pump frequency independently from an engine speed of the internal combustion engine of the motor vehicle.

The water tank (100) is connected to the first inlet (104) via the first fluid line (103). The fuel tank (101) is connected to the second inlet (104) via the second fluid line (103). The emulsion mixer is configured to output an emulsion that comprises the fuel and the water via the outlet (105). A settable mixer is in the mixing chamber (102) and is configured to set a mixture ratio between the water and the fuel in the emulsion.

The hydrogen production system for internal combustion engines includes an intake air scoop, a vacuum block having an air input port system for receiving air from the intake air scoop, a water reservoir connected to the vacuum block for providing water to be mixed with the air in the vacuum block, at least one primary generator assembly with an inlet port for receiving the air/water vapor mixture from the vacuum block and producing a mixture of hydrogen, produced oxygen, and fine hydrogen production vapor from a partially oxidized water fog, and a plurality of secondary hydrogen generator assemblies connected to the primary generator assembly for receiving this mixture. The engine vacuum draws this mixture into the intake manifold to provide an ideal fuel mixture for the engine.

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.

The invention includes methods and devices for preventing excessive NOx formation during the combustion event of a compression-ignition engine with any combustible fuel (diesel, Jet-A, JP8, bio fuel, etc).

A motor vehicle including a water provision unit for providing water to at least one water consumer. Here, a water collection tank, a primary water tank and at least one secondary water tank are provided. The water collection tank is or can be fluidically connected to a water source and the primary water tank, bypassing the water collection tank and the secondary water tank, is fluidically connected to the at least one water consumer. The water collection tank is fluidically connected both directly and indirectly via the at least one secondary water tank to the primary water tank, and the water provision unit includes a water conveying unit which is provided and designed for conveying the water out of the water collection tank in direction of the primary water tank by a gaseous conveying medium.

A fuel pump for a liquid fuel water injection system of a motor vehicle is provided. The fuel pump includes a low-pressure pump that mixes water from a water tank of the motor vehicle with liquid fuel from a fuel tank of the motor vehicle to a liquid fuel water emulsion and provides the liquid fuel water emulsion at a low pressure. A high-pressure pump is in fluid communication with the low-pressure pump and compresses the liquid fuel water emulsion from the low pressure to a high pressure for injecting the liquid fuel water emulsion into an internal combustion engine of the motor vehicle via an injection rail of the motor vehicle.

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.
