    • An injection-pressure setpoint value for the pressure accumulator of an accumulator injection system is specified as a function of the operating point of the engine. The setpoint is specified with the aid of respectively separate characteristic diagrams for the start, idling and load engine operating states. In load operation, the profile of the injection-pressure setpoint value is additionally adapted to the particular requirements of the transient engine operation with a first timing element whose timing characteristics depend on the engine speed. The profile may be briefly raised out of a low engine speed in the case of an acceleration. With the aid of a downstream, second timing element which is independent of the first timing element, sudden transitions in the specification of the setpoint values when the engine operating state changes are suitably smoothed out. Any jumps in the injection-pressure setpoint value are avoided. The gear which has been engaged or the driving style of the driver can be taken into account in the transfer characteristics of the second timing element.
    • 蓄能器注入系统的蓄压器的注射压力设定值被指定为发动机的工作点的函数。 通过分别启动,空转和负载发动机运行状态的独立特性图来指定设定值。 在负载操作中,喷射压力设定值的轮廓额外地适应于具有取决于发动机转速的定时特性的第一定时元件的瞬态发动机运行的特定要求。 在加速的情况下,轮廓可以从低发动机转速中短暂地升高。 借助于独立于第一定时元件的下游的第二定时元件,适当地平滑发动机操作状态改变时在设定值的规格中的突然转变。 避免了喷射压力设定值的任何跳跃。 可以在第二定时元件的传送特性中考虑已经接合的齿轮或驾驶员的驾驶风格。

    • A method of starting an internal combustion engine having an injection system and characteristic variables includes the steps of supplying an injection system with an operating parameter that is determined from characteristic variables, supplying a speed regulator with an initialization value as an initial starting variable, and regulating a speed of an internal combustion engine up to an idling speed with the speed regulator based upon the initialization value. The acceleration to idling speed is carried out with the aid of the speed regulator based on the initialization value. The injection system is supplied with a mass of fuel to be injected. Regulation is carried out with a speed regulator already present in an engine controller. The initialization value is stored in a characteristic curve as a function of coolant temperature. The initialization value is applied to a first injection operation of the internal combustion engine.
