Abstract: A method of controlling a cylinder cut-out mode for an engine comprising the steps of: a) activating a cylinder cut-out mode in which one or more cylinders of the engine are deactivated; b) while the cylinder cut-out mode is active, monitoring one or more deactivation variables; the one or more deactivation variables comprising one or more of: an inlet manifold air temperature; an engine load factor; an engine speed; and an engine coolant temperature; and c) deactivating the cylinder cut-out mode in order to reactivate any deactivated cylinders when at least one of the deactivation variables exceeds its threshold value.
