  • Method of preheating injectors of internal combustion engines
    Patent number: 8096485
    Abstract: In a method and device for preheating an internal combustion engine injector (1) including at least one valve (3) to be activated by an electromagnet (21), in which the coil of the electromagnet (21) is energized before the engine is started, the coil of the electromagnet (21) is periodically powered with a preheating voltage (42), and the current characteristic (33) within the coil is monitored and subjected to an evaluation to detect local current minima (43) and/or maxima (44) caused by armature reactions.
    Type: Grant

  • Method and device for actuating an electromagnetic load
    Patent number: 5592921
    Abstract: A method and a device for actuating an electromagnetic load, in particular a solenoid valve, for influencing the metering of fuel in a diesel internal combustion engine. The load is connected in series with a switching means which is supplied with an actuation signal. In order to identify a switching time of the electromagnetic load, a parameter which characterizes the actuation signal is evaluated.
