4, high-pressure pipeline

High-pressure tubing is connected electronically controlled common rail fuel injection tube and with the access, it should have sufficient fuel flow, fuel flow decreases the pressure drop, high pressure piping systems and pressure fluctuations in the smaller, can withstand the high pressure fuel impact, and at the start the pressure in the common rail can be quickly established. The high-pressure cylinder the length of the pipeline should be equal to a diesel injector each have the same injection pressure, thereby reducing engine cylinder of the deviation between the injector. The high-pressure pipeline should be as short as possible so that the nozzle from the common rail to the minimum pressure loss. BOSCH's foreign economic relations for the high-pressure pipeline of 6 mm diameter was 2.4 mm, Japan, the company installed the high-pressure pipeline foreign economic relations of 8 mm, 3 mm diameter.

3. CONCLUDING REMARKS

As High Pressure Common Rail fuel injection system with the injection timing can be, and the duration of injection, injection pressure, injection of a flexible regulation, the system will enable the use of the diesel engine of the economy, power and emissions performance will have further raised. This requires that we intensify the High Pressure Common Rail System of intensity, the level of China's diesel engine enter a new stage.
