Title: Fuel injection unit
Inventor: TANABE YOSHIKI
IPC: F02D41/38
Filed: 2001-11-16
Abstract: PROBLEM TO BE SOLVED: To improve fuel economy by reducing return fuel and leak fuel while keeping a shape of injection rate waveform. SOLUTION: High pressure fuel supplied from a high pressure fuel supply pump 1 is retained in a high pressure common rail 3. Fuel is supplied from a fuel passage 5 side to a low pressure common rail 10 and the pressure of the low pressure common rail 10 is adjusted by a pressure control valve 13 to retain low pressure fuel. The opening timing of a pressure switching solenoid valve 8 is shifted from that of an injection drive solenoid valve 7 so that the injection rate waveform is in a shape of a boot or a square. The opening timing of the pressure switching solenoid valve 8 is set to be earlier than that of the injector drive solenoid valve 7 by a predetermined time. Therefore, a time where the high pressure fuel acts on an injector 6 or the low pressure common rail 10 becomes short, the leak fuel and return fuel are decreased, and a drive work amount of the high pressure fuel supply pump is decreased to lower an engine load, so that fuel economy is improved. The predetermined period is a time required for keeping a desired shape of the injection rate waveform to ensure the combustion of the desired injection rate waveform.
