käynnistystoimenpide
Käynnistystoimenpide refers to the initial phase of starting an engine or a system. In the context of internal combustion engines, it involves the sequence of actions required to bring the engine from a stationary state to a running condition. This typically includes supplying fuel, air, and an ignition source to the combustion chambers. For a petrol engine, this often means the starter motor engaging with the flywheel to crank the engine, the fuel pump delivering fuel, and the ignition system providing a spark. Diesel engines, on the other hand, rely on compression ignition, where the heat generated by high compression ignites the fuel.
In a broader sense, käynnistystoimenpide can also apply to the startup sequence of electronic systems or complex
