Abstract (en)
The method involves opening the nozzles in a variable sequence. The total fuel quantity for a working cycle is injected via a single nozzle, esp. for partial engine loading. The injection valves are opened at different crankshaft angles and the sequence of opening is varied between successive operating cycles. The difference in crankshaft angles at which the valves are opened is at least 4 degrees. The injection process for all injection nozzles is terminated simultaneously. A sensor connected to a controller determines the crankshaft angle. Two controllable injection devices with nozzles or two directly driven nozzles can be used.
