ABSTRACT:
A method of operating an internal combustion engine with an injection device, wherein the method includes the steps of feeding combustion air to a combustion chamber via an inlet port, injecting fuel into the combustion chamber using a fuel nozzle arranged in the combustion chamber, igniting a formed fuel/air mixture at a certain ignition point using a spark plug arranged in the combustion chamber, and, during the starting of the internal combustion engine, selecting a high-pressure or a low pressure start as a function of a minimum fuel pressure built up in the injection device within a defined number of cycles. The minimum fuel pressure and the number of cycles are selected as a function of a combustion-chamber temperature. The injection of the fuel into the combustion chamber takes place in a timed sequence during the starting operation.
