초록 ▼

The fuel injectors (4) of an internal combustion engine (2) are connected to a pump (10) by means of fuel supply lines (12) which open into the high-pressure part (34) of the injectors (4). The cross-sectional area of the fuel connection (12, 34) between the pump (10) and the injection orifices of the injectors (4) is substantially bigger than the total cross-sectional area of all of the injection orifices of an injector (4). An unrestricted flow path for the pressurized fuel is provided between the pump (10) and the area immediately upstream of the injection orifices. Due to the small pressurized volume of the system, the transient behaviour of the injection system is fast and can easily be matched to the needs of a particular engine application.

대표청구항 ▼

A fuel injection system for an internal combustion engine comprising: at least one electromagnetically operated fuel injector for injecting pressurized fuel into a combustion chamber of the internal combustion engine, said at least one fuel injector having a body portion with a valve seat, at least one discharge orifice and an injector valve member cooperating with said valve seat for closing said discharge orifice and being shiftable to be momentarily lifted from said valve seat for opening said discharge orifice and discharging pressurized fuel into a combustion chamber of the internal combustion engine; a high pressure fuel pump driven by the internal combustion engine; and at least one injection line leading from said pump to said at least one fuel injector and providing a fuel flow path from said pump to a region immediately upstream of said valve seat, the cross-sectional area of said fuel flow path leading from said pump to said region upstream of said valve seat being substantially larger than the total cross-sectional area of all injection orifices of said at least one fuel injector, said fuel flow path being substantially free of flow restrictions to allow a substantially unrestricted fuel communication between said pump and said region around and immediately upstream of said valve seat, the fuel pressure in said fuel flow path before, during and after an injection event as well as in the time interval between any two subsequent injection events being substantially equal to the fuel injection pressure.
