    • A tank venting device for motor vehicles having an internal combustion engine supplied from a fuel tank. The device includes a filter housing, which is connectable to a venting stub of the fuel tank and includes an adsorption filter, whose air inlet is occupied by a shutoff valve and whose air outlet communicates with an intake tube of the engine, and an air feed pump and a diagnosis device. To improve the metering capability for the regeneration mixture aspirated from the filter to the intake tube of the engine, the air feed pump is disposed with a reversible feeding direction between the air outlet of the filter housing and the intake tube of the engine. The air feed pump is controlled in its feeding direction reversal via a multiposition control valve such that the filter housing is located on the intake side of the air feed pump for the duration of filter regeneration, and on the pressure side of the air feed pump for the duration of error diagnosis.
    • 一种用于机动车辆的罐式排气装置,具有从燃料箱供给的内燃机。 该装置包括可连接到燃料箱的排气柱的过滤器壳体,并且包括吸入过滤器,吸入过滤器的空气入口被截止阀占据,并且其空气出口与发动机的进气管连通, 泵和诊断装置。 为了提高从过滤器抽吸到发动机的进气管的再生混合物的计量能力,空气供给泵在过滤器壳体的空气出口和发动机的进气管之间以可逆的进给方向设置。 空气供给泵通过多位控制阀在其进给方向上被反向控制,使得过滤器壳体在过滤器再生期间位于供气泵的进气侧,并且在空气供给泵的压力侧 错误诊断的持续时间。

    • The invention relates to a connecting circuit for a potential-free oxygen probe having a low-potential line and a high-potential line and includes: an amplifier; an offset voltage source connected to the high-potential line forward of the amplifier for applying an offset potential to the high-potential line; the amplifier having an input connected across the high-potential and low-potential lines to receive the difference between the potentials on the lines as an input voltage; the amplifier being adapted to amplify the input voltage and having an output for supplying an output voltage equal to the difference between the offset voltage and the amplified input voltage; and, the offset voltage being selected so as to cause the output voltage to always be greater than zero but less than a pregiven threshold voltage. This connecting circuit makes it possible to determine faults for probe connections, for example, short circuits of the line to ground. The output voltage then drops to 0 V which is not possible for proper operation in view of the offset voltage used. The threshold voltage is exceeded for shorts to battery potential. A method for checking for a correct probe connection is also disclosed.
    • 本发明涉及一种具有低电位线和高电位线的无电位氧探针的连接电路,包括:放大器; 偏移电压源,连接到放大器前方的高电位线,用于向高电位线施加偏移电位; 所述放大器具有连接在所述高电位和低电位线两端的输入端以接收所述线路上的电位之间的差作为输入电压; 放大器适于放大输入电压并具有用于提供等于偏移电压和放大的输入电压之间的差的输出电压的输出; 并且,选择偏移电压以使得输出电压总是大于零但小于预定阈值电压。 该连接电路可以确定探头连接的故障,例如线对地短路。 然后输出电压下降到0 V,鉴于所使用的失调电压,无法正常工作。 超过电池电位时,超过阈值电压。 还公开了一种用于检查正确探针连接的方法。

    • A method and a device for operating an internal combustion engine and an internal combustion engine are described, the fuel being injectable directly into a combustion chamber in particular via at least one first injector and also being injectable into an intake manifold in particular via at least one second injector. For injection of fuel in a full-load operating state of the internal combustion engine, a first selection is made from the at least one first injector and the at least one second injector having a first metering range, including a full-load injection quantity required for the full-load operating state. For injection of fuel in a partial-load operating state of the internal combustion engine, a second selection is made from the at least one first injector and the at least one second injector having a second metering range, including the adjustment of a minimum fuel injection quantity required for operating the internal combustion engine. The first selection and the second selection are made differently, in such a way that only the metering range of the first selection includes the full-load injection quantity and/or that only the metering range of the second selection covers the minimum fuel injection quantity required for operating the internal combustion engine.
