Definitions

• the invention relates to a cover for the cylinder head of a Brennkraf machine.
• cover hoods only have the task of closing the cylinder head upwards, so that no oil can be thrown out, and of dampening the noise of the valve control.
• a hood lined with insulation material is placed on the cylinder head and z. B. sealed with the help of a rubber ring.
• the hood there is an opening for topping up engine oil, which is closed with a lid made of metal or plastic.
• DE-AS 11 45 436 a control housing is shown 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 divided so to speak 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 engages through the hood onto a rocker arm, from which the energy for the drive is taken.
• an ignition distributor was used which was mounted on the cylinder head cover and whose distributor shaft was passed through it. It is the object of the invention to provide a cover for the cylinder head of an internal combustion engine, the S expensive parts for the injection of the internal combustion engine takes auf ⁇ and forms a unit with these parts. This applies in particular to engines in which the injection is integrated in the cylinder head. This results in advantages in terms of maintenance and assembly, space can also be saved and the space required by the unit is reduced considerably.
• Fig. 1 shows schematically a cylinder head (1), which covers several cylinders, with lifted cylinder head cover (2).
• This cylinder head has an overhead camshaft (3), shown here without cams for the sake of simplicity, which drives a parallel-mounted regulator 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 discussed in detail here, which in turn acts on an actuating rod (7) to control the injection, which is also 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 pivoted about an axis (11) which goes through the cover. On its inner side it has a claw (12) which, when the hood is put on, couples with the pin (13) to the lever (6).
• the rod (15) controlled by an expansion element (14) forms a temperature-dependent controlled stop for the lever (6) on its opposite to the actuating rod. overlying side (16). This is used, for example, to increase idling when it is cold.
• the vacuum unit (17) controls a pin (18) that acts on the holder (8).
• a fuel pump (19) is flanged to the rear end of the hood, the drive axis of which is aligned with the controller axis (5) when the hood is in place. Since the Mit Converse ⁇ pins (20) and (21) lie on the same pitch circle around this axis, an automatic coupling is also guaranteed here after touchdown.
• the adjusting screw (22) enables a variable stop of the throttle lever (10).
• FIG. 1 shows a selection of possibilities for coupling the functional parts: longitudinal / transverse movement, pivoting, rotating. It can also be operated manually (10), automatically (14), assisted (17) or with a force output (20, 21). It therefore goes without saying that further functional parts such as boost pressure stop (function such as 17), manual shutdown or increasing the starting quantity by hand (function such as 10) or early adjustment of the start of delivery when the engine is cold (function such as 14) can be used in the Hood can be integrated.
• boost pressure stop function such as 17
• manual shutdown or increasing the starting quantity by hand function such as 10) or early adjustment of the start of delivery when the engine is cold
• function such as 14 can be used in the Hood can be integrated.
• the advantages of the invention are retained, for. B. Accessibility of the parts when the hood is lifted and automatic coupling after putting it back on.
