"* * * 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.
