    摘要： In a fuel injection system for injecting fuel into a combustion chamber of an internal combustion engine by means of a dual fluid injector which includes a nozzle with a nozzle needle normally closing the nozzle and which has formed around the nozzle needle an annular space which is in communication with a fluid source and a pressure chamber in communication with the annular space and the working space of a plunger disposed in the injector so as to be movable between upper and lower end positions but being biased to its upper end position, the plunger working space is in communication with a fuel source via a fuel supply line which includes a control valve and an electromagnetically controlled valve is provided for controlling the admission of a hydraulic operating fluid to the plunger for moving the plunger into the working space for the ejection of the fuel and the fluid from the pressure chamber and the annular space around the nozzle and the fuel supply line includes an electronically controllable valve adapted to close the fuel supply line for a controllable period of time while the plunger is returned to its upper end position to thereby create a vacuum in the working space for drawing an amount of the fluid into the annular space around the nozzle which depends on the time for which the fuel supply line is closed by the control valve.

    摘要： In a fuel injection system for an internal-combustion engine which includes a dual-fluid nozzle which is supplied with fuel by a high-pressure pump and with water by a feed pump providing a substantially lower pressure than the high-pressure pump and which has disposed in a nozzle body a nozzle needle which is spring biased into a closing position where one end of the needle is seated on a valve seat, a fuel supply passage extends to an annular space around the valve needle and a branch passage leads to a control chamber formed at the other end of the valve needle and includes a solenoid valve for controlling the application of pressurized fluid to, and the release thereof from, the other end of the nozzle needle, an additional fluid line extends from the feed pump to the annular space and includes a check valve for permitting flow of additional fluid only toward the annular space and a pressure relief line in communication with the fuel supply passage via a control valve, and a control device is provided for operating the solenoid valve for timed relief of fluid pressure from the control chamber for unseating the nozzle needle and for operating the control valve to either supply fuel under pressure to the annular chamber or releasing pressure from the annular space so as to permit feeding of water into the annular space for subsequent injection, together with the fuel, from the dual-fluid nozzle.

    摘要： In a fuel injection system for a Diesel engine with a high pressure fuel pump supplying fuel under pressure to a common high pressure fuel supply conduit from which the fuel is admitted to a number of fuel injectors having fuel injection control needles engaged by springs so as to be normally seated on a valve seat and a control needle actuator for lifting the control needle off the valve seat under the control of an electronic control unit, the needle includes a cylindrical needle body movable within a cylinder and has slot-shaped orifices formed in its outer surface which are fully covered when the control needle is seated but which are exposed to a degree controllable by the needle actuator for adjustment of the orifice sizes depending on engine operating parameters.

    摘要： An internal combustion engine has an exhaust gas turbocharger with an exhaust gas turbine and a compressor. In addition, an air-driven turbine is provided which is torsionally connected to the compressor and to which combustion air can be supplied via an adjustable shut-off element. For operation of the exhaust gas turbocharger over a wide operating spectrum, an additional duct is provided between compressor inlet and the air inlet of the air turbine, the air supply in the additional duct being adjustable by the shut-off element. In the lower load range, in the case where the required boost pressure falls below a threshold value, the additional duct is opened by means of the shut-off element and the air supply to the compressor inlet is reduced.
