ryhmäsuuttimet

Ryhmäsuuttimet, a Finnish term, translates to "group nozzles" or "gang nozzles" in English. This term refers to a type of fuel injector system used in internal combustion engines, particularly in older gasoline engines. Instead of individual injectors for each cylinder, a group injector system employs a single unit that houses multiple injectors, typically one for each cylinder in a bank or manifold.

This design simplifies the fuel delivery system by consolidating the injectors into one component. The control unit then actuates the individual injectors within the group as needed. While historically used, group injector systems have largely been superseded by individual port fuel injection or direct injection systems in modern vehicles due to advantages in precise fuel delivery, atomization, and diagnostic capabilities offered by individual injectors. However, the concept of consolidating multiple injection points within a single housing can still be found in some specialized industrial or high-performance applications where specific flow characteristics or packaging constraints are paramount.
