Abstract
A method for controlling an internal combustion engine operated with direct fuel injection may include, during a transition phase after the end of an overrun cut-off with resumption of fuel injection and normal operation of the internal combustion engine, shifting an injection start time (SOI) by an adaptation value (ΔSOI) in relation to an injection start time (SOI) which lies later than an injection start time (SOI_Norm) determined during normal operation of the internal combustion engine.
Claims20
A method for controlling an internal combustion engine operated with direct fuel injection, the method comprising:
- during a transition phase after the end of an overrun cut-off with resumption of fuel injection and normal operation of the internal combustion engine, shifting an injection start time (SOI) by an adaptation value (ΔSOI) in relation to an injection start time (SOI) which lies later than an injection start time (SOI_Norm) determined during normal operation of the internal combustion engine.
An internal combustion engine operated with direct fuel injection, the device comprising:
- at least one combustion chamber;
- a fuel injector metering fuel into the at least one combustion chamber;
- and
- a controller operable to adjust the timing and amount of fuel metered by the fuel injector, wherein the controller is programmed to control a transition phase after the end of an overrun cut-off with resumption of fuel injection and normal operation of the internal combustion engine by shifting an injection start time (SOI) by an adaptation value (ΔSOI) in relation to an injection start time (SOI) which lies later than an injection start time (SOI Norm) determined during normal operation of the internal combustion engine.
