  • Switchable air intake system for multi-cylinder internal combustion engine
    Patent number: 7252064
    Abstract: A switchable air intake system for a multicylinder internal combustion engine has at least one short and one long intake manifold whose cross sections are controllable by at least one regulating unit as a function of operating parameters (in particular the rotational speed of the internal combustion engine). The short intake manifold for a first cylinder bank row and the long intake manifold for a second cylinder bank row of the internal combustion engine, are controllable via a joint regulating unit (56, 58).

  • Arrangement for decoupling the torsional vibrations in a gear transmission
    Patent number: 4947707
    Abstract: A toothed springy decoupling gear set consisting of a center gear and of two coaxial split gears abutting on both sides thereof serve as arrangement for decoupling torsional vibrations in a gear transmission, for example, in a control transmission of a reciprocating piston engine. Drawsprings located tangentially in the center gear protrude with their two spring ends out of the center gear and are suspended at the left and at the right split gear.

  • Fuel supply device for internal combustion engines
    Patent number: 4556034
    Abstract: A fuel supply device includes a housing having at least one injection valve which is held at both ends by plug-in devices. At the end remote from the injection opening the injection valve cooperates with a holding element which includes fuel ducts and which has a head portion in a bore formed in the housing. The bore is connected to a fuel line. In addition, spaced apart sealing elements are provided on the head portion to define a fuel supply area between the holding element and the bore.
