    摘要： In a scalable driver device having a plurality of driver stages whose outputs are connected to a common terminal contact for providing a common output signal, drive parameters of the driver stages, individually or in groups, are so dimensioned that the difference of the edge rise times and/or fall times of the output signal from one active driver stage to the next driver stage to be activated is substantially equal to the difference of the edge rise times and/or fall times from a next activated driver stage to the one activated after that.

    摘要： The invention is directed to a method of metering fuel to the engine during warm-up operation which precedes normal operation of the engine during which a first amount of fuel is metered to the engine. The engine is equipped with a lambda control and a device for detecting a variable suitable for distinguishing warm-up operation and normal operation of the engine. A predetermined corrective factor (FWL) is provided in dependence upon the variable. A second amount of fuel is metered to the engine during the warm-up operation which is increased by the corrective factor (FWL) so that the second amount is greater than the first amount. Lambda control is engaged during the warm-up operation and provides a desired lambda value (.lambda..sub.des). A quantity is formed indicative of the mean deviation of the actual lambda value (.lambda..sub.act) from the desired lambda value (.lambda..sub.des) when the lambda control is engaged. The quantity is applied to increase the corrective factor (FWL) when the quantity indicates that the mean value of the actual lambda value (.lambda..sub.act) is greater than the desired lambda value (.lambda..sub.des) and decrease the corrective factor (FWL) when the quantity indicates that the mean value of the actual lambda value (.lambda..sub.act) is less than the desired lambda value (.lambda..sub.des).
