Abstract: A method for operating a common-rail fuel supply system of an internal combustion engine includes determining, dependent on an operating point of the engine, a set point rate of delivery of the high-pressure pumping device, and a set point pressure for the pressure storage system under high pressure, determining, dependent on a deviation between the set point pressure and an actual pressure in the pressure storage system, for a first part quantity of the throttle valves a closed-loop control portion for the position of the respective throttle valve, and activating the first part quantity of the throttle valves with the closed-loop control portion in addition to open-loop control for only the respective throttle valve of the first part quantity of the throttle valves. The, or each, throttle valve of a second part quantity of the throttle valves is exclusively activated with the open-loop control portion.

Abstract: A post injection is utilized in a more effective manner. In an internal combustion engine which is provided with a fuel injection valve for injecting fuel into a cylinder of the internal combustion engine, in cases where a post injection is carried out after a main injection of fuel from the fuel injection valve, when a rotation speed of the internal combustion engine is equal to or more than a first predetermined speed, a penetration force of fuel in the post injection is made larger than a penetration force of fuel in the main injection, whereas when the rotation speed of the internal combustion engine is less than a second predetermined speed which is equal to or less than the first predetermined speed, the penetration force of fuel in the post injection is made smaller than the penetration force of fuel in the main injection.

The fuel control system includes a fuel injector for directly injecting the fuel into the combustion chamber, a tumble flow generator for generating the tumble flow within the combustion chamber, and a fuel injector controlling module for causing the fuel injector to inject the fuel at a first injection timing and then inject a smaller amount of fuel than an amount injected at the first injection timing, in a direction opposing a positive direction of the tumble flow at a second injection timing, the first injection timing designed to be in an intake stroke of the cylinder, the second injection timing designed to be in a latter half of the compression stroke of the cylinder.

Abstract: A fuel management system that separates the three-dimensional functions of fuel injection pressure, volume and timing and thus eliminates co-dimensional dependencies. The system of the invention utilizes volumetric injection control and is based on displacement of a predetermined volume rather than volume generated by flow due to pressure with respect to time, as in prior art systems. In one of its simplest configurations, the fuel management system combines a pair of "sister" injectors and a volumetric injection control assembly comprised of a simple displacement piston which free floats a given distance to deliver fuel alternately to each injector. When one injector's solenoid valve operates to activate it's main injection, it simultaneously loads the adjacent injector with a predetermined volume of fuel for the adjacent injector's main volume injection. Throttling fuel volume is controlled by controlling the length of the cylinder's barrel containing the free floating piston.

The mechanism includes a main passage, a chamber, a primary valve connecting the main passage to the chamber, a piston disposed within the chamber, a spring biasing the piston toward the primary valve and an adjustment compartment. A wall separates the chamber from the adjustment compartment, and a removable cap encloses the adjustment compartment. Apparatus is provided for adjusting the biasing force of the spring and travel limits of the piston. Adjustment can be accomplished to vary fluid characteristics in the fuel delivered to the injector without the need to disassemble the mechanism or disconnect the mechanism from the fuel system.
