Common Rail Cummins Injectors

The common rail injection oil supply system is composed of high pressure oil pump, common oil supply pipe, injector, electronic control unit (ECU) and some pipeline pressure sensors. Each injector in the system is connected with the common oil supply pipe through its own high pressure oil pipe, which plays a role of hydraulic pressure storage for the injector. During operation, the high-pressure oil pump delivers fuel to the common oil supply pipe with high pressure, and the high-pressure oil pump, pressure sensor and ECU form a closed-loop operation to realize accurate control of the oil pressure in the common oil supply pipe, completely changing the phenomenon that the oil supply pressure changes with the engine speed. Its main features are as follows:

1. The injection timing and fuel metering are completely separated, and the injection pressure and injection process are timely controlled by ECU.

2. According to the working condition of the engine, the injection pressure, injection start point and duration of each cylinder can be adjusted, so as to pursue the best control point of injection.

3. It can achieve high injection pressure and pre injection of diesel oil.

Compared with gasoline engine, diesel engine has lower fuel consumption rate (30% lower than gasoline engine on average), and lower diesel price, so the fuel economy is better.

Common rail cummins injectors play an important role in the common rail injection system. At the same time, common rail cummins injectors are a good choice for fuel saving and low price.

Maintenance of Common Rail Cummins Injectors

In order to avoid abnormal damage to common rail cummins injectors, it is necessary to change the fuel according to the season and maintain the diesel filter regularly. Avoid the use of poor fuel and poor filters, in addition to the need to avoid long-term high load operation of the engine. At the same time, it should be pointed out that the common rail system belongs to the high-pressure system. Do not disassemble it without permission to avoid injury. Common rail Cummins injectors belong to the precision parts. Please select a professional equipment supplier for after-sales service and repair. Do not disassemble without permission to avoid secondary damage to the injector.
