The main advantages of the common rail direct fuel injection can be summarized in reduction of exhaust and noise emissions, better fuel efficiency and improved overall engine performance. The system consists of a high-pressure pump, injectors, a rail, and an electronic control unit.
The common rail is a long metal cylinder. It receives the fuel from the pump and distributes it to the injectors under extremely high pressure. The increase in the fuel pressure is a result of the latest engines’ design. Both, diesel and gasoline engines tend to become smaller and lighter for better fuel efficiency and improved performance which increases the fuel pressure and sets entirely new standards for the manufacturing of a high-quality common rail.
