Abstract (en)

[origin: WO2018210819A1] The invention relates to a method for operating an internal combustion engine having a motor having a first number of cylinders and a second number of cylinders and a charger arrangement, wherein a charge air flow supplied to the motor is compressed by means of at least one compressor and an exhaust gas flow channeled from the motor is applied to at least one turbine. According to the invention, the method further comprises the step: in a main operating mode, operating the first number of cylinders in two-stroke mode and the second number of cylinders in four-stroke mode, wherein a flushing gradient is greater for the cylinders operated in two-stroke mode than for the cylinders operated in four-stroke mode.
