摘要:
An atomization system for fuels, particularly for charging a chemical reformer for obtaining hydrogen, features at least one metering device, accommodated in a supporting device, for metering fuel into a temperature-adjusted substance stream, which introduces the fuel directly into the temperature-adjusted substance stream without the interpolation of a supply line.
摘要:
A dosing mechanism for fuels, particularly for the input into a chemical reformer to obtain hydrogen, has a metering-in device for metering fuel into a supply line, which opens out at at least one dosing aperture into a transporting line transporting a tempered material flow. A holding device for accommodating the metering-in device has an insulating body which thermally insulates the metering-in device from the transporting line that transports the tempered material flow.

摘要:
A metering unit for metering liquid and/or gaseous educts by means of a feed pump for a fuel cell system, including at least one lead line for delivering an educt flow, at least one control piston, and a differential pressure valve for regulating the educt flow; the differential pressure valve has a regulatable throttling cross section, which is variable automatically, as a function of a flow pressure dictated by the control piston, in order to regulate the educt flow. The lead line leads to the control piston, and between the control piston and the differential pressure valve a first and a second connecting line are provided.

摘要:
The invention relates to a device and a method for producing an operating medium for a motor vehicle, especially for use in the exhaust gas post-treatment of the motor vehicle. According to said method, an operating medium is produced from an initial product and air using a catalyst device. Said initial product is heated and mixed with air and the heated mixture of initial product/air is fed to the catalyst device. A part of the initial product is converted to the gaseous phase by means of a preheating element and is entrained by a stream of air when leaving the preheating element, said stream of air leading to a combustion chamber. The method allows to efficiently produce an operating medium, especially a reducing agent for regenerating NOx storage catalysts.
