Common Rail is a next generation fuel injection system that uses a Nozzle Head Rotor that is under constant to inject pressurized fuel into the vehicle engine. The pressure ensures that the fuel breaks down while governing the injection that helps to mix with air. The harmful emission from the vehicle is reduced when the mixture of air and the fuel takes place. This is the highlight point for the outcome of engine's invention. It gives engine developers to further reduce exhaust emissions and reduce engine noise significantly.
The principle of conventional engine and the CRDi are almost same. The only difference is, the CRDi is controlled by an electronic control unit while the other was controlled mechanically. This unit regulates the amount of fuel injected and also the pressure used and required for both injection and combustion.
In a conventional engine system, the fuel pump of high pressure stores a pool of fuel at a pressure of about 29,00 pound force per square inch or psi in a common rail which a tube. Actually this tube divides into a fuel injector valve and controlled by computer and consists of precision machined nozzle and a Diesel Plunger Element, driven by solenoid valve. The fuel quantity and the pressure is regulated by the engine with the help of an on board computer.
It follows the injection time and at the same time increases the pressure at which the fuel is injected which results in the improved combustion and atomization. This helps in lower emission, lower consumption of fuel and increased fuel efficiency. The common rail deliverers 25% more power and torque compared to conventional engines though it has its own pros and cons like any other new technology. Since diesel is cheaper than petrol most people prefers this, however the engine cost is costlier than a conventional engine. Come to cnboqiang to browse more details.
