    • The invention relates to a method for supplying current to a glow plug in a running diesel engine after reaching the operating temperature thereof by a series of current pulses, wherein a piston of the engine carries out a work cycle comprising several strokes and the glow plug is supplied with current as a function of the strokes of the work cycle such that the electric current supplied in each work cycle is mainly supplied at a predetermined, steady stroke of the piston, wherein control time intervals that follow each other are defined, during which up to two switching processes can be triggered by a control device, by which the glow plug can be connected to a voltage source for creating a current pulse or can be disconnected from the voltage source for ending a current pulse. According to the invention, the control time intervals have a duration that can be varied by the control device as a function of the rotational speed of the engine.
    • 本发明涉及一种在一系列电流脉冲达到其工作温度之后向运行中的柴油发动机中的电热塞提供电流的方法,其中发动机的活塞执行包括若干冲程的工作循环,并且电热塞是 根据工作循环的行程提供电流,使得在每个工作循环中提供的电流主要在活塞的预定的稳定行程下供应,其中定义了彼此之间的控制时间间隔,在此期间 两个切换过程可以由控制装置触发,通过该控制装置,电热塞可以连接到用于产生电流脉冲的电压源,或者可以与电压源断开以终止电流脉冲。 根据本发明,控制时间间隔具有可以通过控制装置作为发动机的转速的函数而改变的持续时间。
