Common Rail Injector Nozzles and Parts

Common rail now dominates the market. Consequently, demand for this type of repair is constantly increasing, and VERTEX AUTOMOTIVE SYSTEMS has invested heavily in this sector. And developed any parts for the repair of CR Injectors like Nozzles , Control Valves, Shims etc.

WHAT IS COMMON RAIL

Common rail refers to a small accumulation tank called Rail where the pressure of the fuel remains almost constant and always available in order to supply the electronic injectors and therefore for an optimum injection. The protection of the he need to reduce the consumption of fuel and to make the diesel engines more silent and better performing are the key factors that determined the study and development of the common rail system. The first vehicles with Common Rail installation were introduced into the market in 1997.

SYSTEM FUNCTION

A pump inhales the fuel from the tank continuously sends the quantity of requested fuel towards a second pump "HIGH

PRESSURE PUMP" by making it pass from any impurity which would cause a premature wear of its components. The

high-pressure pump compresses the fuel at a pressure of 1350 bar and transfers it through a connection pipe to the high

develops the function of mitigating the pressure oscillations caused by the opening and closing of the injectors and by the continuous discharges of the pump. The fuel is then transferred from the Rail through some connection injectors, which - instructed by an electromagnetic valve of fuel directly into the combustion chamber of the engine. The fuel in excess, required for the opening of the nozzles, is sent back to the tan along with the leakages of fuel coming from the pressure regulation valve and from the high pressure pump itself. In this type of system, the quantity of injection is being established by the driver through the accelerator pedal while the initial stage and the pressure of injection are calculated and controlled by the electronic control unit "EDC". Through the accelerator pedal’s sensor, the electronic control unit registers the driver’s intention while, thanks to other sensors, it registers the exercising conditions of the engine and vehicle and

acquired – it carries out the intervention for the engine regulation.
