- it can also be ensured in internal combustion engines with fewer than four cylinders that the piston of at least one cylinder of the internal combustion engine is in an optimal position for carrying out the starting process according to the invention.
- An electromotive starter can be used to move the pistons in the cylinders, which acts on the crankshaft of the internal combustion engine and rotates it.
- the fuel compressed in a combustion chamber of a cylinder be ignited shortly before the top dead center of the piston of the respective cylinder is reached at the end of the compression phase.

Then 5 is ignited with the help of the spark plug 9, so that the piston 2 is driven in the now following working phase by the expansion of the ignited fuel.
- the homogeneous operation of the internal combustion engine 1 the fuel is injected from the injection valve 8 into the combustion chamber 4 during an induction phase caused by the piston 2. Due to the air sucked in at the same time, the injected fuel is swirled 5 and thus in the
- Combustion chamber 4 is distributed essentially uniformly (homogeneously). The fuel-air mixture is then compressed during the compression phase in order to then be ignited by the spark plug 9. The piston 2 is driven by the expansion of the ignited fuel.
- the driven piston 2 sets a crankshaft 10 into a rotary movement, via which the wheels of the motor vehicle are ultimately driven.

- the phases of all cylinders 3 can be inverted in a simple manner, i.e. it is switched between the compression phase and the discharge phase and between the work phase and the suction phase.
- An unsuccessful first attempt to start is, for example, if the
- each compression phase that has passed through can be suitably shortened by belatedly or prematurely closing the corresponding inlet valves 5 - these are open during the intake phase that takes place before the compression phase.
