Common Rail Fuel System
With a common rail fuel system, an extremely high fuel pressure is created in the supply pump and this is fed directly to the common rail which is located on the engine and is connected to the injectors.

Compared to previous diesel engines, the Common-rail system supplies
highly pressurized fuel injection even at low engine speeds. As the
highly pressurized fuel exits the injector’s very small holes (which are
about the same diameter as a human hair), the fuel is sent to the
combustion chamber as an extremely fine spray (particle of fuel is
small).
Fuel Injection
Fuel injection is controlled electronically by an ECU (Electrical control unit).
The ECU detects the driving conditions through the signals from various sensors and calculates the correct injection volume and timing. Then, the ECU sends a signal to the injector to operate for precise and accurate control in the same way electronic fuel injection functions on petrol engines.
