Abstract
A method is provided for setting combustion parameters of an internal combustion engine operated with liquefied natural gas, the combustion parameters being sensed during operation of the internal combustion engine and being stored upon shutoff of the internal combustion engine. Also provided is a controller for carrying out the method. Provision is made that during a stoppage of the internal combustion engine, the duration of the stoppage, the ambient temperature and/or tank temperature, and the pressure in a liquefied gas tank are sensed; the influence thereof on a required adaptation of the combustion parameters that are to be set is identified from a characteristics diagram; and from the stored combustion parameters and the adaptation, initial combustion parameters are identified and are used upon startup of the internal combustion engine in order to control it.
