摘要:
The present invention relates to an internal combustion engine which is used in particular in motor vehicle having a reformer for generating hydrogen, whereby the reformer has a single operating mode in which it generates as much reformate as needed or even more for purification of the maximum quantity of exhaust gas generated, whereby a distributor apparatus is situated at the output end of the reformer and the distributor apparatus is connected at the output end to an intake train of the internal combustion engine and to an ammonia generator, whereby the ammonia generator is connected at the output end upstream from an SCR catalyst to an exhaust train of the internal combustion engine, whereby the distributor apparatus allocates the reformate between the intake train and the ammonia generator as a function of the operating state of the internal combustion engine.

A fuel cell system includes a fuel cell (12), a burner (34), which can be operated with fuel or/and fuel cell waste gas as desired. A heat exchanger arrangement (32) is provided to transfer heat generated in the burner (34) to air to be fed into the fuel cell (12) or/and to hydrogen-containing gas to be fed into the fuel cell (12).
摘要:
A fuel cell system for a vehicle including at least one reformer, at least one fuel cell and at least one reformer-reformate burner arrangement. The at least one reformer is configured for the production of a reformate as a fuel gas. The at least one fuel cell receives the reformate from the at least one reformer. The at least one reformer-reformate burner arrangement is connected to the fuel cell, where either prior to reaching an anti-condensation temperature of residual hydrocarbons and water vapor the combustion gases, which are produced in the reformer-reformate burner arrangement, are immediately directed into the fuel cell or after reaching the anti-condensation temperature the reformate is immediately directed into the fuel cell.
摘要:
A device for producing an air/hydrocarbon mixture has an atomizing arrangement (10) with a hydrocarbon feed means (14) and with an air feed means (16, 18, 20) for producing the air/hydrocarbon mixture by atomizing liquid hydrocarbon. A heating arrangement (37), with which hydrocarbon (28) applied to the surface (26) of the first air flow guiding element (22) can be heated, is provided in a first air flow guiding element (22). The heated and consequently less viscous hydrocarbon (28) is moved to an atomizing lip (30) by corresponding air flows, which are generated by the air flow space areas (18, 20), and is atomized there, so that an air/hydrocarbon mixture suitable for combustion or reforming is formed.
摘要:
A conditioning system for a vehicle comprises an evaporator, positioned in an air conducting channel means, of an air conditioning unit, by means of which evaporator heat and/or moisture can be removed from the air to be introduced into a vehicle interior, a heating means being provided at the evaporator for at least local heating of the same.
摘要:
A heating system for a vehicle includes a heater (12) with a first electric heating device (24), which can be operated to ignite an air/fuel mixture present in a combustion chamber (16), and with a second electric heating device (22), which can be operated to support the evaporation of the fuel into the combustion chamber (16). An actuating device (26) is provided for the heater (12), which actuating device puts the heater (12) into operation after a start command has been generated. A first start command generating device (30, 36, 26), which can be actuated by a user to generate a start command is provided along with a second start command generating device (32, 38, 26), which generates a start command according to an operating program. The actuating device (26) is designed to operate the second electric heating device (22) at a lower heat output after a start command has been generated by means of the second start command generating device (32, 38, 26) than after the generation of a start command by means of the first start command generating device (30, 36, 26).
