Patent
Enthone Gmbh and Volkswagen AG | Date: 2017-03-29

The invention relates to a corrosion protection layer system for metal surfaces, said layer system comprising as the two top most layers: a) a discontinuous nickel-phosphorous layer and b) a chromium layer plated from a trivalent chromium electrolyte solution, as well as to a method of producing such a layer system. The inventive layer system is capable to combine the good corrosion resistance of the nickel-phosphorous layer against sodium chloride with the protective power of the chromium layer from the trivalent plating process against magnesium and calcium salts, especially without the need for any post-treatment.

The invention relates to a motor vehicle lighting device (1) comprising at least one first optical waveguide (10) having at least one light coupling-in surface (LE1) and at least one light exit surface (LA1) assigned thereto, and at least one second optical waveguide (20) having at least one light coupling-in surface (LE2) and at least one light exit surface (LA2) assigned thereto. At least one first light source (11) for feeding in light is assigned to the first optical waveguide (10) and at least one second light source (21) for feeding in light is assigned to the second optical waveguide (20). Furthermore, the optical waveguides (10, 20) are optically coupled to one another in such a way that the light from the second light source (21) can pass at least partly to the light exit surface (LA1) of the first optical waveguide (10) but the light from the first light source (11) cannot pass to the light exit surface (LA2) of the second optical waveguide (20). The invention proposes that the light coupling-in surfaces (LE1 and respectively LE2) are arranged in each case with respect to the light exit surfaces (LA1 and respectively LA2) in such a way that an imaginary surface normal (N1 and respectively N2) to a light coupling-in surface (LE1 and respectively LE2) falls within the light exit surface (LA1 and respectively LA2) assigned to the latter (LE1 and respectively LE2). A very compact construction of the motor vehicle lighting device (1) is possible in this way.


The invention relates to an SCR catalysts system and to a method for operating a reducing agent dosing of an SCR catalyst system (14) of an internal combustion engine (10), wherein the SCR catalyst system (14) has a first SCR exhaust gas purification device (16) and an SCR catalyst (18) downstream thereof, as well as a reducing agent dosing device (20) for dosing a reducing agent into the exhaust gas flow, downstream of the first SCR exhaust gas purification device (16). According to the invention, if an exhaust gas mass flow (m_Abgas) is greater than a predetermined exhaust gas mass flow threshold (m_max), and a temperature (T_SCR) of the downstream SCR catalyst (18) is greater than a predetermined minimum temperature (T_SCR_min), the reducing agent dosing changes into a high-load operating mode (III), in which a desired reducing agent filling level (NH3_SPF_soll) of the first SCR exhaust gas purification device (16) is reduced or lowered to zero.


The invention relates to a rotor (1) of an electric machine, the rotor having a circumferential surface (13) and a permanent magnet structure (2) on the circumferential surface (13). A contour (20) of the permanent magnet structure (2) has a stepped section (21) comprising multiple steps (22a-22d), each step (22a-22d) having a first extent (23a-23d) oriented substantially perpendicularly to a circumferential direction (u) of the circumferential surface (13) and a second extent (24a-24d) oriented parallel to the circumferential direction (u) and connecting the first extent (23a-23d) to a first extent (23b-23e) of a neighbouring step (22b-22e). The first extent (23a) of a first step (22a) differs from the first extent (23b) of a second step (22b) neighbouring the first step (22a) and/or the second extent (24a) of a first step (22a) differs from the second extent (24b) of the second step (22b).
