    摘要: A device to investigate the flow movement in cylindrical components of reciprocating piston internal combustion engines, which flow movement is generated by a flow-guiding system located, as seen in the flow direction, upstream of the cylindrical component, has at least one rotatable measuring vane in the cylindrical component, the axis of rotation of which intersects the axis of the cylindrical component at an adjustable angle other than 0.degree.. A shaft supporting the measuring vane is connected to a device to evaluate the frequency of rotation and/or the position of the angle of the measuring vane in order to determine one or more parameters of the flow movement in the cylindrical component.

    摘要: An intake and fuel/air mixing system for multi-cylinder externally ignited internal combustion engines with at least two inlet valves per cylinder, at least two separate intake pipe arms per cylinder assigned to the inlet valves, and fuel injection. The first intake pipe arms per cylinder are combined into a first group and other intake pipe arms per cylinder are combined into at least one other group. Each group is assigned one throttling member. The first group comprises a common fuel injection, and one injection each is assigned to the intake pipe arms or inlet ports of the other group or other groups. The throttling members of the individual groups are controlled in such a manner that for the region of low air flow rates the first group opens first and the other group or other groups are opened as a function of the speed and load with higher air flow rates.

    摘要: A spark-ignition reciprocating piston engine has at least one piston cylinder, at least one inlet port arranged at an end of the cylinder, an inlet valve located at the inlet port and that is movable to open and close the inlet port, and an inlet conduit leading to the inlet port for feeding a fluid from a fuel feed to an inlet area of the inlet port. The engine includes a partition arranged within the inlet conduit which divides the inlet conduit into at least two partial conduits over at least a portion of a length of the inlet conduit between the fuel feed and the inlet area. At least one of the partial conduits is connected to the fuel feed. The partial conduits converge directly in front of the inlet port to form the inlet area. The partition is located within a plane that extends essentially transversely to an axis of the cylinder at least in the inlet area. The partition has an end edge facing the inlet area, and has at least one portion that is movable to deflect a flow of the fluid on blow-by from the inlet conduit, through the inlet port, and into the cylinder. A controllable actuation arrangement is connected to the portion for changing a distance from the end edge to the inlet port.
