摘要： A method for determining at least one rail pressure/closing current value pair for a pressure control valve of a common rail injection system of an internal combustion engine includes the following steps: operating the common rail injection system in an MU control mode; reducing the control current for the pressure control valve; detecting the pressure curve over time in the common rail and determining the rail pressure; determining the closing current based on the detected pressure curve; and associating the determined rail pressure and the determined closing current with a rail pressure/closing current value pair.

摘要： A device is provided for preventing the engine from stalling in a vehicle equipped with a diesel injection system, particularly a common-rail injection system. The device comprises a volume flow control valve, a high-pressure fuel pump, a pressure control valve, one or more injectors and a control unit. The control unit carries out a pressure control by controlling the volume pressure control valve in the idle state of the engine in a first operating mode, monitors whether a working point is present at which a release of air from the fuel is carried out and, in the event such a working point is detected, initiates a second operating mode in which a pressure control is carried out by controlling the pressure control valve.

摘要： Provided is a control apparatus for an internal combustion engine that can suppress blowback of in-cylinder residual gas to an intake passage when reverting from a fuel-cut operation accompanied by valve stopping control of an intake valve while suppressing an oil ascent during execution of the fuel-cut operation, and a control apparatus for a vehicle equipped with the internal combustion engine. When executing a fuel-cut operation accompanied by intake valve stopping control, advancement control of the opening/closing timing of an exhaust valve (32) is executed. If the advancement control is being executed in a case where a request to revert from the fuel-cut operation has been detected, an advance amount of the opening/closing timing of the exhaust valve (32) is retarded so as to become less than or equal to a predetermined value.

摘要： A pressure relief valve includes a valve body having a valve seat fluidly positioned between an inlet and an outlet. A valve member is movable among a first position, a second position, and a third position. The valve member is in contact with the valve seat and fluidly blocks the inlet from the outlet at the first position. At the second position of the valve member, the inlet is fluidly connected to the outlet via a small flow area. The inlet is fluidly connected to the outlet via a large flow area when the valve member is at the third position. An electrical actuator is attached to the valve body and is operably coupled to move the valve member when energized. The valve member includes an opening hydraulic surface exposed to fluid pressure in the inlet when at the first position. A spring is operably positioned to bias the valve member toward the second position when the valve member is at the third position.
