    • A control unit (50) makes a single control signal available for driving the through-flow control valves (TEV1, TEV2) (51, 52). Through-flow valve (TEV2) has a larger maximum through flow than through-flow control valve (TEV1). A delay circuit is indicated by the phantom outline (52′) and is mounted at the valve stage TEV2 (52). The delay circuit includes an electric delay element (53) with the aid of which the original control signal is delayed in time by an amount &Dgr;t1 relative to the control signal of control valve (TEV1). The resulting delayed signal is supplied to an AND-gate (54) together with the original control signal. Accordingly, a control signal is present at the output of the AND-gate for the control valve (TEV2). The time delay makes possible the exclusive activation of the through-flow control valve (TEV1) (51) at low pulse duty factors. In this way, a high small quantity meterability is achieved. Starting at a specific pregivable switch-in time, the control valve (TEV2) (52) is switched in so that a very large through flow is possible. The invention thereby makes possible excellent meterability at low as well as at high through flows.
    • 控制单元(50)使单个控制信号可用于驱动通流控制阀(TEV1,TEV2)(51,52)。 通流阀(TEV2)通过流量比通流控制阀(TEV1)具有更大的最大流量。 延迟电路由幻影轮廓(52')表示,并安装在阀级TEV2(52)处。 延迟电路包括电延迟元件(53),借助于该延迟元件,原始控制信号相对于控制阀(TEV1)的控制信号在时间上延迟量DELTAt1。 所产生的延迟信号与原始控制信号一起提供给与门(54)。 因此,控制信号存在于用于控制阀的与门的输出端(TEV2)。 时间延迟使得在低脉冲占空因数下独占激活通流控制阀(TEV1)(51)成为可能。 以这种方式实现了高的小数量度量。 从特定的预先接通时间开始,控制阀(TEV2)(52)被切换,使得可以有非常大的通流。 因此,本发明使得在低流量和高通量流量下具有优异的可测量性。

    • An internal combustion engine (10) is operated in dependence upon operating characteristic variables such as rpm (nmot) of a crankshaft (18), temperature (Tmot) of the internal combustion engine (10) and/or temperature of the intake air (Taev). In the method, a temperature (Taevk) of the inducted air in the combustion chamber (16) is, at least in approximation, obtained from a detected or modeled temperature (Taev) of the inducted air in a region remote from the combustion chamber. To simplify the programming, it is suggested that the determination of the temperature (Taevk) of the inducted air in the combustion chamber (16) takes place under the assumption that the inducted air has a modeled or detected initial temperature (Taev) and that the intake air comes into thermal contact with a typical component (22) during a contact time (tcontact) which is typical for a type of the internal combustion engine (10) and for an operating state of the internal combustion engine (10) and the typical component has a modeled or detected temperature (Tev).
