Abstract

Disclosed is a method of controlling an internal combustion engine 110 of an automotive system 100. The engine system comprises an exhaust system having at least one after-treatment device 280, an EGR valve 320, a throttle valve 330 and a turbocharger 230 comprising a variable geometry turbine 250 controlled by a VGT actuator 290. When the internal combustion engine 110 is in a cut-off phase, the engine speed is below a speed threshold THR_Spd and a diesel particulate filters 281 inlet temperature DPF_inl temp is lower than a temperature threshold THR_Trnp then the EGR valve 320 duty cycle is set equal to a first speed dependent array, the VGT actuator 290 duty cycle is set equal to a second speed dependent array and the throttle valve 330 duty cycle is set equal to a third speed dependent array. The arrangement is used to provide sufficient heat to regenerate the diesel particulate filter when the engine is in a cut-off or warm-up phase.
