Definitions

  • the invention relates to a cover for the cylinder head of an internal combustion engine.
  • cover hoods only have the task of closing the cylinder head at the top, so that no oil can be thrown out, and to dampen the noise of the valve control.
  • a hood which may be lined with insulating material, is placed on the cylinder head and e.g. sealed with the help of a rubber ring.
  • DE-AS 11 45 436 shows a control housing in which the valve control is installed.
  • This control housing is placed on the cylinder head and closed at the top with a cover. With this arrangement, the cylinder head is, so to speak, divided so that the complete valve control can be manufactured as a single component.
  • a cylinder head cover with an attached fuel pump is known. Through an opening in the hood, a drive pin extends through the hood onto a rocker arm, from which the energy for the drive is drawn.
  • an ignition distributor was used, which was mounted on the cylinder head cover and the distributor shaft was passed through it.
  • FR-A-2 495 225 a cover is known which has an elastic stop.
  • the control parts are made in a separate room and not in connection with the cover.
  • the solution is to design a hood of an internal combustion engine in such a way that it additionally performs actively controlling functions for the injection of the internal combustion engine and controls the operation of the internal combustion engine. This enables easy access, adjustment and manufacture of the entire injection control and reduces the space required for injection and control.
  • Fig. 1 shows schematically a cylinder head (1), which covers several cylinders, with the cylinder head cover (2) raised.
  • This cylinder head has an overhead camshaft (3), shown here for simplicity without cams, which drives a parallel-mounted control shaft (5) at its rear end via a pair of wheels (4).
  • a rotatably mounted lever (6) is adjusted by the controller, which is not dealt with in more detail here, which in turn acts on an actuating rod (7) for controlling the injection, which is likewise accommodated in the cylinder head.
  • the injection quantity can be set to zero delivery by means of a shut-off lever (8).
  • the throttle lever (10) is pivotally mounted about an axis (11) which passes through the cover. On its inner side it has a claw (12) which, when the hood is put on, couples with the pin (13) on the lever (6).
  • the rod (15) controlled by an expansion element (14) forms a temperature-dependent stop for the lever (6) on its opposite side from the adjusting rod Page (16). This is used, for example, to increase idle speed in the cold.
  • the vacuum box (17) controls a pin (18), which acts on the rack (8).
  • a fuel pump (19) is flanged to the rear end of the hood, the drive axis of which, when the hood is in place, is aligned with the regulator axis (5). Since the driver pins (20) and (21) lie on the same pitch circle around this axis, automatic coupling is also ensured here after mounting.
  • the adjusting screw (22). enables a variable stop of the throttle lever (10).
  • Fig. 1 shows a selection of possibilities of coupling the functional parts: longitudinal-transverse movement, swiveling, turning.
  • the operation as by hand (10), automatic (14), auxiliary control (17) or power delivery (20, 21) is arbitrary. It therefore goes without saying that in this way additional functional parts such as boost pressure stop (function like 17), manual shutdown or increasing the starting quantity by hand (function like 10) or early adjustment of the start of delivery when the engine is cold (function like 14) are integrated into the hood can be.
  • boost pressure stop function like 17
  • manual shutdown or increasing the starting quantity by hand
  • function like 14 early adjustment of the start of delivery when the engine is cold
  • the advantages of the invention are retained, e.g. Accessibility of the parts when the hood is lifted off and automatic coupling after refitting.
