Definitions

  • the present invention relates to a mechanically controllable valve lift adjustment (see EP-A-780 547).
  • the present invention further relates to an internal combustion engine with a mechanical adjustable valve stroke adjustment and a method for regulating the valve strokes in internal combustion engines.
  • a vacuum occurs when the load changes from full to partial load in the cylinders due to the more fuel than needed in the cylinders is sucked. This increases the fuel consumption of the internal combustion engine, and unburned fuel may leak into the environment.
  • the object is therefore to provide a device with which the fuel consumption of an internal combustion engine can be reduced.
  • This task is accomplished by providing a mechanically controllable valve lift adjustment according to claim 1 and claim 2 and solved by a method according to claim 10.
  • valve lift adjustment according to the invention additionally a roller rocker arm, which on the one hand matches the working curve of the Lever cooperates and is driven by this and on the other hand with the valve cooperates and moves it.
  • the valve lift adjustment has a means with which the lift lever is rotatable and slidably mounted in a backdrop. This is preferably Means a role.
  • the backdrop takes up the means and thus represents its leadership, within which the means and with it the lifting lever moves under pressure and / or tension.
  • the backdrop can have any shape that is chosen by the person skilled in the art that the lifting lever preferably along a certain straight line and / or curve is movable.
  • the backdrop preferably has a substantially rectangular shape, whereby the short sides of the rectangle are preferably designed in the form of a semicircle are. This shape of the backdrop is particularly suitable for holding roles.
  • This backdrop can be horizontal or vertical or at any angle Be arranged horizontally or vertically.
  • the backdrop is also preferably in the form of a circular arc, the shape of which preferably by the geometry of the roller finger follower, in particular by the Role of the roller finger follower is defined.
  • the backdrop is it e.g. possible to implement a so-called 0-stroke, in which the respective Valve remains completely closed.
  • the shape of the backdrop is that of the respective one Valve is assigned, preferably different, whereby different Have the stroke characteristics realized per valve.
  • the valve lift adjustment according to the invention has two means that interact with the lifting lever and this in the Move the backdrop or move it to a specific location in the backdrop for a fix certain time.
  • One means is preferably an eccentric shaft, the other A means is preferably a return spring, the return spring being the lifting lever presses against the eccentric shaft and against the camshaft.
  • the eccentric shaft is preferably driven by an electric motor, a stepper motor and / or driven by a worm or gear transmission.
  • the central axis of the means that is associated with the Camshaft interacts on a horizontal plane with the central axis of the Camshaft.
  • the means that cooperate with the camshaft is a roller.
  • valve control according to the invention is suitable for valves of any kind.
  • the valves are valves of internal combustion engines, particularly preferred Intake valves for internal combustion engines.
  • Another object of the present invention therefore relates to an internal combustion engine, which has at least one valve control according to the invention.
  • At least 4, particularly preferably 6, 8 or 12, are preferably according to the invention Valve controls are available in the internal combustion engine.
  • the lifting levers are preferably rotatable mounted on a shaft, the ends of which are guided in scenes that are in the cylinder head are located.
  • the cylinder head has a special bearing cap on.
  • Another object of the present invention is a method for control of the stroke of an intake valve of an internal combustion engine using the Valve control according to the invention, in which the lifting lever corresponding to the Performance requirement for the internal combustion engine is shifted in the backdrop.
  • the lifting lever is moved in this way and for a certain time Position held that the valve or the roller rocker arm with part of the Working curve of the lifting lever is in contact, which reduces the stroke of the valve causes.
  • the lifting lever At full load, the lifting lever is moved in this way and for a certain time Position held that the valve or the roller rocker arm with part of the Working curve of the lifting lever is in contact with the maximum stroke of the valve causes.
  • the present invention has the advantage that the valve lift depending on the performance requirement can be increased or decreased.
  • Valve stroke adjustment reduces the gas exchange work in Otto engines and it This results in fuel savings of up to 10% compared to valve control according to the state of the art.
  • the mechanical control is much easier and thus cheaper to produce than z.
  • the valve control according to the invention is very robust and not maintenance-prone.
  • a lifting lever 1 is slidably mounted with the roller 2 in a link 3 (only partially shown).
  • the roller can also be a shaft on which each lifting lever is rotatably mounted.
  • the lifting lever is moved by the eccentric shaft 5 and the return spring 5 in the backdrop.
  • the direction in which the lifting lever is moved in the link is shown by line 14.
  • the person skilled in the art understands that the lifting lever 1 can also be held in a specific position within the backdrop by the two means 5.
  • the eccentric shaft is driven by a stepper motor (not shown).
  • the lifting lever 1 has a further roller 9, which is connected to the camshaft 6 cooperates, and which drives the lifting lever 1.
  • the lifting lever 1 has a working curve 4, which approximately has the shape of a parabola. This working curve is in contact with the roller 15, the is attached to the roller rocker arm 7. The roller rocker arm 7 in turn moves the valve 8.
  • the central axis 13 of the roller 9 is below the Central axis 10 of the camshaft 6, or the central axis 13 of the roller 9 is as shown in dashed lines, in the same horizontal plane as the central axis 10 of the Camshaft 6 arranged.
