COMMON RAIL DIRECT INJECTION/ CDRi
COMMON RAIL DIRECT INJECTION/ CDRi: COMPONENTS, WORKING PRINCIPLE, FUNCTION AND ADVANTAGE/DISADVANTAGE Bosch launched the first common rail system in 1997. The system is named after the shared high-pressure reservoir (common rail) that supplies all the cylinders with fuel. With conventional diesel injection systems, the fuel pressure has to be generated individually for each injection. With the common rail system, however, pressure generation and injection are separate, meaning that the fuel is constantly available at the required pressure for injection. Common rail systems have a modular design. Each system consists of a high-pressure pump, injectors, a rail, and an electronic control unit. A common rail is one of the most important components in a diesel and gasoline direct injection system. The main difference between a direct and a standard injection is the delivery of fuel and the way how this one mixes with incoming air. In the direct injection system, the fuel is directly inj
