    摘要: A fuel injection system for multi-cylinder internal combustion engines, which has one injection unit per cylinder. Each injection unit includes one injection valve, one control valve, one flow limiting valve and one injection nozzle and is supplied with fuel via a fuel delivery line. Each injection unit also has a control unit which actuates the applicable control valve. This actuated control valve then actuates the associated injection valve, which in turn opens the fuel delivery line upstream of the injection nozzle. The flow limiting valve disposed upstream of the injection valve in the fuel delivery line blocks fuel flow when the fuel quantity flowing through the flow limiting valve attains a maximum fuel quantity, and the flow limiting valve does not open again until the fuel delivery line is blocked downstream of the flow limiting valve. To improve this system, each injection unit is assigned a sensor, with which a leak downstream of the flow limiting valve can be indicated; the control unit increases the injection duration, for the cylinder affected by a leak, enough though the correlated fuel quantity is greater than the maximum fuel quantity.

    摘要: A multi-cylinder internal combustion engine with an air intake system and an exhaust gas collection system has an exhaust gas recirculation apparatus for reducing toxic emissions. To operate the engine with a turbocharger and charge air cooler, the exhaust gas recirculation apparatus has an exhaust gas distributor, branching off from which is a number of end pipes corresponding to the number of cylinders of the engine. The exahust gas distributor is connected to the exhaust gas pipe of one cylinder, while the exhaust gas pipes of the other cylinders communicate with an exhaust gas manifold. The end pipes of the exhaust gas distributor each discharge into cylinder intake pipes immediately upstream of the inlet valve of the cylinders.

    摘要: To control the fuel injection pressure, in particular in high-pressure injection in self-igniting internal combustion engines, the pumping or supply phase of a cam-driven, intermittently operating pump piston of a fuel injection pump is determined by the closing time of a relief-metering valve and controlled in such a manner that the closing of the relief-metering valve for the supply onset (FB) is earlier, by the amount .DELTA..alpha., than the opening of control valves by way of which the fuel pumped by the pump piston is supplied to the individual injection locations. By means of the initial pumping amount or pre-stroke (.DELTA.h or .DELTA..alpha.), fuel is pumped into a closed system, and the injection pressure present at the injection valve at the instant of the opening (SB) is thus controlled.

    摘要: Device for injecting of fuel into internal combustion engines with an injection jet is provided with a stretched tension wire as a locking spring element for an outwardly opening valve locking member. The pretension of the tension wire is influenced by the current flow in an electrical current circuit which is fed to an electric resistor element being installed into the injection jet. The resistor element may be formed by the tension wire itself or by coil of an electromagnet, whose anchor is coupled with the tension wire. Thus, the opening pressure (P.sub.o) of the injection jet or the injection process can be controlled in a simple manner or may be formed accurately in accordance with a predetermined principle.
