摘要： A method for controlling an engine is disclosed. The method may include receiving a pressure data set of a combustion event. The pressure data set may correspond to a temporal development of a cylinder pressure during the combustion event in a cylinder. The method may also include determining using a controller that the received pressure data set indicates an actual ignition timing within a preset ignition timing window. Further, the method may include deriving an actual combustion duration (D1) of the combustion event from the received pressure data set. The method may also include determining whether the actual combustion duration (D1) is shorter than a preset combustion duration for the cylinder. In addition, the method may include providing a control signal to control an operation of the internal combustion engine when the actual combustion duration is shorter than the preset combustion duration.

摘要： A method of operating a gas or dual fuel engine having a plurality of cylinders, includes monitoring a characteristic of each of the plurality of cylinders during operation of the gas or dual fuel engine. The method also includes detecting a pre-ignition condition associated with one or more cylinders of the plurality of cylinders based on the monitored characteristic. The method further includes reducing fuel supply to the one or more cylinders having the pre-ignition condition. The fuel supply to remaining cylinders of the plurality of cylinders is increased, to maintain a constant power output of the gas or dual fuel engine. The method further includes adjusting an amount of air supplied to each of the plurality of cylinders based on the increased amount of fuel supplied to the remaining cylinders, to maintain an air-to-fuel ratio within a desired range.

摘要： A fuel injection system supplies fuel at high pressure to an internal combustion engine via at least two high-pressure fuel pumps and a high-pressure fuel distribution line. The high-pressure fuel pumps can operate in a first pump mode and a second pump mode, which differ in the amount of fuel that is pumped. A control unit alternately operates the high-pressure fuel pumps such that, during a first time period, at least one of the high-pressure fuel pumps is operated in the first pump mode and all other high-pressure fuel pumps are simultaneously operated in the second pump mode and such that, during a second time period, at least one of the high-pressure fuel pumps, which was operated in the second pump mode during the first time period, is operated in the first pump mode and the remaining high-pressure fuel pumps are simultaneously operated in the second pump mode.
