METHOD AND A CONTROL DEVICE FOR CONTROLLING AN ENGINE

A method for controlling an engine in either a first mode in which the engine is fuelled by a first fuel, or in a second mode in which the engine is fuelled by a mixture of the first fuel and a second fuel, the method comprising the steps of programming the engine to operate initially in the first m...

Beschreibung
Zusammenfassung:	A method for controlling an engine in either a first mode in which the engine is fuelled by a first fuel, or in a second mode in which the engine is fuelled by a mixture of the first fuel and a second fuel, the method comprising the steps of programming the engine to operate initially in the first mode, repeatedly sensing a plurality of first variables and obtaining a measured value for each sensed first variable, and emitting a first input signal dependent on the measured value of each sensed first variable, causing a first output signal, comprising a plurality of injector control signals, to be emitted in dependence on the first input signals for controlling the amount of the first fuel supplied to the engine, switching the mode of operation to the second mode, selecting one or more of the injector control signals to produce a first modified signal, which determines the amount of first fuel supplied to the engine and generating a second calculated signal, which determines the amount of second fuel supplied to the engine.
