Abstract

The invention relates to a method of controlling operation of an ICE arrangement (), comprising acquiring () a first signal indicative of a required torque; acquiring () a second signal indicative of a temperature (T) of an EATS (); and when the second signal indicates that the temperature (T) of the EATS () is lower than a predefined first threshold temperature (T): determining () an amount of second fuel () needed to deliver the required torque; supplying the amount of second fuel (); controlling () an inlet valve () to allow flow of a second fuel-air mix into the cylinder (); injecting first fuel () into the cylinder () when the second fuel-air mix is compressed by the piston (), resulting in flame propagation ignition of the second fuel-air mix; and controlling () and outlet valve () to allow flow of exhaust from the cylinder () during an exhaust stroke (ES) of the piston ().
