Dci 1 1 engine common rail system

This electronically controlled fuel injection technology uses * * * rail technology to optimize the fuel supply of each nozzle. Technical data from a series of pressure, temperature and speed sensors are processed by V-MAC electronic control system to control fuel flow, oil pressure and injection timing. The application of the system has brought excellent performance of high performance, low fuel consumption, flexible driving and low noise.

"* * * rail" fuel injection system is a patent of Renault truck, which was first equipped on Premium 420 in 2000. Since then, the efficiency of the system has been verified many times.

Fuel injection is divided into pre-injection, main injection and post-injection, which effectively ensures the high accuracy of the system. Compared with the traditional injection system, the fuel combustion efficiency is improved and the power is stronger.

* * The main advantages of the track system can be summarized as follows:

Low fuel consumption, low noise at full speed and high reliability, minimizing visible and invisible emission pollution.

* * * Rail engine adopts high-pressure fuel injection (1, 500 Pa), and at any engine speed and load, a large-capacity fuel injection pump provides it with constant-pressure fuel.
