    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 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 compression ignition, in which fuel is injected as a pre-injection and main injection directly into a working space by means of an injection nozzle having a plurality of injection holes, with the pre-jection taking place in a clocked manner. In order to minimize the moistening of the walls of the combustion chamber, a combustion chamber is provided, in which are arranged an injection nozzle in the region of a cylinder center axis in the cylinder head and a piston recess arranged in the piston head, with an approximately centrally situated piston recess projection being arranged in the piston recess. The stroke of a nozzle needle of the injection nozzle is set in such a manner that a restricting of the range of the injected fuel jets is obtained.
