Title:
燃料噴射システム
Document Type and Number:
Japanese Patent JP2008508470
Kind Code:
A
Abstract:
A common rail fuel injection system having a low-pressure region from which a high-pressure fuel pump acts on fuel with high pressure and delivers it to a high-pressure fuel accumulator from which fuel is supplied to injectors that inject the highly pressurized fuel into the combustion chamber of an internal combustion engine in which the high-pressure pump, the high-pressure fuel accumulator, and the injectors are associated with a high-pump, pressure region. In order to avoid undesirable delays in the starting of the internal combustion engine, a check valve device is connected between the low-pressure region and the high-pressure region so that when a negative pressure is generated in the high-pressure region, fuel flows from the low-pressure region into the high-pressure region.
