Definitions
- the invention relates to an ignition system for an internal combustion engine with the Features of the preamble of claim 1.
- Such an ignition system is known in principle from DE 297 01 235 U. There is about the problem of sealing the spark plug to the outside when the inside Cylinder head located spark plug / ignition coil unit with a high voltage supply is provided through a mounting hole on the cylinder head fits on the cylinder head cover. In the known ignition system a sealing body is provided between the mounting opening and the unit.
- the invention has for its object an ignition system of the aforementioned Art to create, in a structurally simple manner, the risk of damage the electrical connection of the spark plug / ignition coil unit is eliminated.
- the molded body which is preferably made of elastic material, serves primarily Ignition coil rotation lock line. This eliminates a special mechanical Load on the electrical supply for the ignition coil. Somehow Rigid mechanical connection between the ignition coil and spark plug not mandatory.
- the correct rotational position of the ignition coil can be checked by appropriate Shape design of the molded body can be achieved. For example, one is sufficient simple marking, for example with a reference marking on the edge the mounting opening corresponds when the ignition coil is in the correct Rotational position sits.
- a constructive improvement of the invention consists in using the molded body to provide a boom that extends over the clear cross section of the mounting opening protrudes and engages in a recording. This can be done by shaping the ignition coil can be reached that the ignition coil when properly Assembly presses the molded body into the receptacle. The correct fit of the molded body and thus the ignition coil can be easily recognized.
- the molded body 1 shown in FIGS. 1 to 3 consists of elastic material, e.g. Silicone. He sits between a mounting opening, not shown Cylinder head of an internal combustion engine and also not shown Ignition coil, which is part of an ignition coil / spark plug unit (so-called single coil ignition system) is.
- the molded body 1 consists essentially of a tubular cylinder section 2 and is provided with a boom 3, which has a groove 4 in a receptacle engages on the edge of the spark plug shaft 6 (not shown).
- the molded body 1 also has a sealing labyrinth 5, which has the shape of a closed Has round channel 5 'and over the circumference of the cylinder section 2 circulates almost completely.
- the labyrinth 5 has a closely adjacent circumference Entry and exit opening. Air enters the through the inlet opening Sealing labyrinth 5, this air enters the interior of the Spark plug shaft 6. Airborne moisture droplets are in the Round channel 5 'separated and thus do not get into the interior of the candle shaft 6.
- the ignition coil is secured in the rotational position with respect to the molded body 1 for example a groove into which a corresponding, e.g. rib-shaped recess of the molded body 1 engages.
- the molded body 1 Due to the rotation of the molded body 1 with respect to the assembly opening / spark plug shaft 6 and the position of the ignition coil with respect to the Shaped body 1 is thus an arrangement of the ignition coil secured in the rotational position within the assembly opening 2 reached.
- the electrical leads of the ignition coil are subject therefore no special mechanical stress even in long-term operation.
- the ignition coil is only inserted and is promoted solely by friction supported by the elastic material of the molded body.
- the shaped body shown Due to its material and shape, height tolerances of up to approx Record 2mm while maintaining the labyrinth and sealing function. At the same time there is a vibration decoupling of the coil since there is no direct mechanical Connection exists between the coil and the cylinder head of the internal combustion engine.
