Abstract (en)
[origin: WO2011144393A1] The invention relates to a method for reducing the temperature tolerance of glow plugs, in which method, in a first step, the glow plugs of an auto-ignition internal combustion engine are classified under at least two temperature classes, wherein at least one temperature class encompasses a temperature range above a setpoint temperature range, at least one temperature class encompasses a temperature range below the setpoint temperature range, and/or one temperature class encompasses the setpoint temperature range. In a second step, the actuation voltage of glow plugs which have been assigned to a temperature class which encompasses a temperature range above the setpoint temperature range is lowered and the actuation voltage of glow plugs which have been assigned to a temperature class which encompasses a temperature range below the setpoint temperature range is raised. The invention also relates to a device for carrying out the method.
