Abstract (en)
[origin: EP1311004A2] A multiplier (30) uses a temperature (16) for a piezoelectric element (10) to adjust a voltage set-point (14). An adjusted voltage set-point (28) to be calculated is formed from a voltage set-point (14) through multiplication with an adjustment value/multiplier (24) and/or through addition with an adjustment value/summand. The multiplier/summand are formed from specific data for the piezoelectric element and for tolerances in an injector.
