Commonrailruiskutusta
Commonrailruiskutusta, or common rail injection, is a diesel engine fuel-injection technology in which fuel is pumped to a single high-pressure rail and delivered to multiple electronically controlled injectors. The high-pressure rail is supplied by a pump and its pressure is regulated by an electronic control system to maintain a consistent, variable pressure independent of the pump’s output. Each injector is controlled by the engine control unit (ECU), allowing precise timing and duration of injection events.
The key idea is decoupling fuel delivery from the engine’s mechanical pump. This enables highly accurate control
Typical components include a high-pressure pump, the common rail, fuel injectors, a rail pressure sensor, a pressure
Common rail systems have become standard in many modern diesel engines since the late 1990s and are
