    摘要: The invention relates to an injection valve, comprising a control chamber (15) with a control piston (16) that is functionally linked with a nozzle needle (35). The control chamber (15) is linked, via an inlet throttle (13), with pressurized fuel, and with an outlet throttle (14) with a valve chamber (9). A servo valve (5) is disposed in the valve chamber (9), said servo valve opening a connection between the valve chamber (9) and a return element (40) depending on its position. The inventive injection valve further comprises a bypass throttle (12) that is interposed between the fuel feed line and the valve chamber.

    摘要: A turbosupercharging system is provided having two turbosuperchargers of the same type and dimensions, connected in parallel. A cut-in valve is installed in an exhaust manifold in which the second turbine is installed. When the valve is closed, the entire exhaust blast coming from the engine is directed to the first turbine. In this manner, even at low engine speeds, the first turbine can deliver an effective amount of power to its compressor, thereby introducing a detectable supercharge into the cylinders of the internal combustion engine. This supercharge also holds a biased nonreturn valve which is built into the manifold pressure line of the second tubosupercharger is a closed position. When the cut-in valve is completely open the exhaust blast is divided between both turbines, thereby allowing a pressure build up in the manifold pressure line of the second turbosupercharger. This pressure builds up until the biased nonreturn valve is suddenly opened and compressed air from both compressors is delivered to the cylinders. A specially adapted control system is provided for the nonreturn valve in order to prevent power loss or pulsations due to the cutting in of the second turbosupercharger.
