ADVANTAGES OF MOTOR COMMON RAIL | DCI

The following video was suggested through the mail blog (high1energy@gmail.com) by Diego Arredondo de Bolivia. The video shows the operation of a motor or Common-Rail DCI initially introduced by Bosch and is being spread in today’s automotive systems.

The common-rail system or common duct system is an electronic fuel injection for diesel engines where the oil is drawn directly from the fuel tank to a high pressure pump which in turn sends it to a common conduit all injectors and high pressure cylinder. Source: Wikipedia.

Advantages of the Common Rail Injection Systems

The first important reason why the Common Rail Injection Systems (CRI) are a better choice than traditional engine technologies are superior technical properties.

For starters, the new common rail technology provides better performance. One reason for this is that performance is independent of engine speed and load variations. The new CRI injection system eliminates the connection between filling pressure and the camshaft to allow the nozzles to be loaded with fuel from a fuel tank under high pressure, resulting in the independence of speed and load variations. Given the above information, we can say that high performance can be achieved even with lower properties and operating conditions.

One can also say that the new system eliminates the mechanical part of the mechanism and makes the injection is an electronic process, with high efficiency and performance offered by advances in electronic control of injection.

In addition to the expected performance, CRI systems also offer better handling. First, produce more energy (which optimizes handling) due to the aerosol spray and the improved accuracy resulting from the injection technology that provides the injection needle in a direct movement, better driving characteristics with 10 percent more power and torque are achieved. Furthermore, the proper functioning of the motor also means greater driving dynamics, and therefore better handling. Delphi Corporation also reports that an accelerometer is used by observing the engine operating conditions and combustion control. This allows the engine to run on a cleaner, quieter and more smoothly.

The second main superiority provided by the common rail injection systems is the development of the economy. First, the new HR systems require low amounts of fuel in the combustion chamber. Because CRI systems take technology to improve spray atomization most successful and accurate.

In addition to its low fuel consumption, the second major economic advantage CRI system is to save costs in different parts. For example, the new HR systems work with a battery voltage lower than other traditional systems. As highlighted Delphi Corporation, working with low battery voltage, less energy is spent on the injection process, which also simplifies the design of the engine electronics. This makes it clear that thanks to new technologies, offer significant cost savings in the design, production and use of vehicles. Furthermore, elimination of feedback mechanism makes cold fuel injection systems are less expensive new generation that any injection system.

The final feature of the common rail injection systems is that they operate with lower production of pollution of any motor system, making them more environmentally friendly. CRI Ls engines produce less emission of nitrogen oxides (NOx). As pointed out by Delphi Corporation, a small injection of fuel stable and accurate manifests itself in the combustion chamber in reducing emissions.

In summary, these are the main advantages of a Common-Rail system:

* Increased performance with increased torque at low engine speeds
* Lower fuel consumption
* Lower emissions of soot from the use of diesel particulate filter (DPF) in the exhaust system.
* Noise Reduction
* Closed Loop Control
* Programmable features that allow the efficient use of biofuels
* Electronic Diagnostics
* Reduction of NOx emissions
