Abstract:
Method for calibrating the injection time (.alpha.) of a first fuel (6') in a diesel engine (2), comprising the following steps:feeding under pressure an adjustment fluid (6) to an injection adjuster (3) which includes an adjuster plunger (4);running the diesel engine (2) at a constant speed (r);adjusting the adjuster plunger with the aid of the pressure of the adjustment fluid (6), said adjuster plunger being coupled to a roller-bearing ring (15) for adjusting the injection time (.alpha.);measuring the fuel consumption of the diesel engine (2);recording the injection time (.alpha.), when the fuel consumption converts from varying to being constant, and/or vice versa;comparing the recorded injection time (.alpha.) with a predetermined injection time (.alpha..sub.1); andcalibrating the injection adjuster (3) by regulating the pressure of the adjustment fluid (6) so that the adjuster plunger (4) is set in a position which corresponds to an injection time (.alpha.) which accords with the predetermined injection time (.alpha..sub.1).
