A device for supplying injection water capable of stably supplying the water to a water injection system of a vehicle. The device for supplying injection water includes a storage unit configured to store water, a management unit mounted on the storage unit and configured to detect a state of the water stored in the storage unit and manage the water, a transport unit connected to the storage unit through the management unit and configured to outwardly move the water, and an integrated controller configured to control operations of the management unit and the storage unit.

An electrolysis system includes an injector with a conical tapered resonant capacitor wave-guide forming two voltage zones of polarity. An anode probe establishes a positive charge reaction of a capacitive voltage region. An anode exciter component has a conically tapered tip with a tapering diameter that diminishes toward a tip end and determines a guide path through the injector for a dielectric medium. A cathode probe is retained within the anode probe for establishing a negative charge reaction of the capacitive voltage region. A cathode exciter component includes a cathode tapered tip conically parallel with the anode conically tapered tip. The anode and cathode end portions form a compression exiting nozzle port. The compression exiting nozzle port receives a mixture of water mist and fuel gases to focus the mixture into a trigger zone of fuel gas combustion, which triggers an electrolysis reaction in the water mist.

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.

Described is a liquid heater having a housing, in which a flow channel runs from an inlet to an outlet, a heating resistor arranged within the housing for heating liquid flowing through the flow channel, control electronics which are arranged in an interior space of the housing, the interior space being sealed off from the flow channel, and a plug connector attached to the housing. Provided according to this disclosure, the plug connector has a vent duct which is closed by a membrane and which leads to the interior space sealed against the ingress of liquid, in which interior space the control electronics are arranged.

The present invention relates to a heater for a vehicle system for injecting anaqueous solution in an air intake line upstream of a combustion chamber of aninternal combustion engine, or in the combustion chamber of the internal combustion engine, said heater comprising at least one flexible part which comprises at least one metallic resistive track embedded in an insulating material, said insulating material comprising at least one antimicrobial compound and/or being coated by at least one layer containing at least one antimicrobial compound. The invention relates also to a vehicle system for injecting an aqueous solution in an air intake line upstream of a combustion chamber of an internal combustion engine, or in the combustion chamber of the internal combustion engine comprising said heater.

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.

A liquid filter for water separation and/or particle filtration of a fuel and/or aqueous solution, in particular a urea solution, and/or water, in particular in a motor vehicle, is described. The liquid filter has at least one filter and/or coalescer medium that is made of a non-woven fabric that has fibers and/or threads having elementary silver.

An exchangeable filter of a treatment device has a housing with a housing pot and a housing cover connected to the open side of the housing pot. The exchangeable filter is connectable to a connecting head of the treatment device with a bayonet-type connecting device. The connecting device has a housing connecting part on the housing interacting with a head connecting part of the connecting head for connecting the connecting device. The housing has an inlet for a fluid to be treated connectable to a supply conduit of the treatment head and an outlet for the treated fluid connectable to a discharge conduit of the treatment head. The housing pot has a rim at the open side of the housing pot. The rim radially outwardly surrounds the housing connecting part and axially projects past the housing connecting part in a direction away from the housing bottom.

The present invention provides systems, methods and apparatus to overcome limitations of liquid fuel engine combustion. Liquid fuel is mixed with superheated water which vaporizes, mixes with air and ignites within the injector nozzle. The injector nozzles then accelerate the mixture into the engine combustion chamber where unburned fuel vapor mixes and burns. Combustion begins the instant of injection and increases uniformly. Combustion pressure builds progressively. Combustion of fuel vapor is more ideal, and better controlled. As part of the system and apparatus, the present disclosure also includes a low-cost high-speed solenoid valve which produces shorter injection pulses. It also includes a high-speed, high-air-volume solenoid fuel valve. In addition, the present invention and its disclosure create tools to develop and optimize this new method of fuel vapor injection.
