tulitusjärjestelmän

The term "tulitusjärjestelmän" is Finnish and translates to "firing system" or "ignition system" in English. It refers to the mechanism responsible for initiating combustion in various devices, most commonly in firearms. A firing system in a firearm is designed to strike a primer, which in turn ignites the propellant charge, causing the projectile to be expelled.

There are several types of firing systems found in firearms. Percussion cap systems, historically significant, use a small metal cap containing a sensitive explosive compound that is struck by a hammer. Modern firearms predominantly utilize self-contained cartridges, where the primer is integrated into the base of the cartridge. The firing pin, driven by a spring, strikes this primer upon trigger activation.

In some contexts, "tulitusjärjestelmän" might also refer to the ignition systems in engines, such as internal combustion engines. Here, it involves a spark plug that generates an electrical spark at the precise moment to ignite the fuel-air mixture within the cylinder. The overall function remains consistent: to reliably initiate a controlled explosion or rapid combustion. The design and components of a firing system are crucial for the safe and effective operation of the device it serves.
