摘要： Methods and systems are provided for operating a lift pump of an engine fuel system. In one example, a method may comprise closed loop operating a lift pump of a fuel system based on a difference between a desired fuel rail pressure and an estimated fuel rail pressure, and open loop operating the lift pump to the desired fuel rail pressure in response to a fuel flow rate in a direction of a fuel rail through a check valve positioned between the lift pump and the fuel rail decreasing to a threshold. Thus, outputs from a fuel rail pressure sensor may not be used to adjust lift pump operation when an amount of fuel flowing to the fuel rail decreases to a threshold.

摘要： A fuel pump for a direct injection internal combustion engine having a housing defining a pump chamber. Driven and idler toothed gears are rotatably mounted within the pump chamber so that the driven and idler gears are in mesh with each other at a predetermined location in the pump chamber. A fluid inlet is formed through the housing and open to an inlet subchamber in the pump chamber. A fluid outlet is also formed through the housing and open to an outlet subchamber in the pump chamber. A pressure relief passageway fluidly connects the inlet subchamber to the outlet subchamber and a valve is disposed in series with the pressure relief passageway. A control circuit controls the actuation of the valve to control the pump pressure at the pump outlet.

摘要： An internal combustion engine has a pressure accumulator, a high-pressure pump, a controllable actuator, and camshaft. The high-pressure pump includes a pump piston movably arranged in a cylinder chamber. The pump piston is supported on the camshaft and thus influences an open volume of the cylinder chamber depending on a rotation of the camshaft. The cylinder chamber is hydraulically coupled to the pressure accumulator to pump the fluid into the pressure accumulator. The actuator drives the camshaft such that the camshaft rotates about the camshaft's longitudinal axis in a specified angular range. The high-pressure pump is controlled prior to an expected motor start such that the high-pressure pump is in a self-priming operating state and the actuator is controlled such that the camshaft rotates about the camshaft longitudinal axis in the specified angular range at least once in a first direction and at least once in an opposite second direction.

摘要： A method, comprising: operating an engine cylinder with fuel from a first injector and not a second injector and activating the second injector in response to a rail pressure increase of a fuel rail, the fuel rail coupled to the second injector. In this way, degradation of the second injector may be reduced by activating the second injector and allowing fuel flow through the second injector to reduce the pressure and temperature of the fuel rail.

摘要： A valve arrangement for a high pressure pump includes a pump housing with a depression, and a valve housing configured to be inserted in the depression, and a clamping disc. The valve housing has at least one radial projection with a first axial boundary surface and a second axial boundary surface arranged opposite the first axial boundary surface, wherein the clamping disc extends radially over the radial projection of the valve housing and has a third axial boundary surface that corresponds with the second axial boundary surface of the valve housing. On the circumferential side, the clamping disc has a thread that can be screwed into a thread on the inner side of the depression to brace the valve housing onto the first boundary surface.

摘要： A common rail fuel system includes a common rail supplied by an inlet metered high pressure pump and fluidly connected to a plurality of zero-leak fuel injectors. An electronic controller controls pressure in the common rail predominantly responsive to a rail pressure error when outside of an overshoot avoidance condition corresponding to the error being less than a first threshold and a time rate of change of the error being greater than a second threshold. Pressure in the common rail is controlled predominantly responsive to the time rate of change of the error during the overshoot avoidance condition.
