Fuel injection system for an internal combustion engine |
摘要 |
In a fuel injection system for an internal combustion engine with a high pressure pump for supplying pressurized fuel to fuel injection valves and a multi-way valve disposed in the high pressure fuel line to the fuel injector for controlling the fuel flow to the injector, the multi-way valve is a spool valve which includes an actuator for positioning the spool to provide selectively a flow connection between the high pressure pump and the injection valve or between the injection valve and a fuel return line and which further includes an inflow throttle structure forming a pressure control device. A pressure sensor is arranged between the spool valve and the fuel injector and supplies the sensed pressure value to a controller which compares the value with predetermined set values and provides a correction value to the multi-way valve actuator for the correction of the pressure of the fuel supplied to the fuel injection valve.
